Low-cost AIS receiver

AIS doesn't have to be expensive. With dAISy all you need to start tracking ships are a VHF antenna, a Windows, Mac, Linux or Android device, and a clear view of the sea. This marine AIS receiver wor…

dAISy works great with OpenCPN and OpenPlotter

OpenCPN, an open source chart plotter and navigation software, can be used with devices like dAISy to track ships on a map. Any software running on a PC, Mac or small Linux computer that accepts AIS data from a serial input will work with dAISy.

Several of our customers built chart plotters based on Raspberry Pi 2, OpenCPN and dAISy. A detailed write-up can be found here. A similar project based on the UDOO Neo single board computer can be found here.

Disclaimer: WE DO NOT RECOMMEND to rely solely on dAISy for navigation and collision avoidance!

Reporting to MarineTraffic

dAISy is well suited to report nearby ship traffic to websites and services like MarineTraffic, FleetMon, AISHub or Pocket Mariner.

A user of an early prototype of dAISy documented how to configure a Linux system like Raspberry Pi to report directly to MarineTraffic here.

Recently he even did away with the Raspberry Pi and reports to MarineTraffic just with dAISy and an ESP8266 WiFi module running an Arduino sketch. This is based on the auxiliary serial output and definitely needs some tinkering, i.e. for advanced users only!

An alternative approach is to connect dAISy to a Linux computer (like the Raspberry Pi) running Kplex. Kplex is a NMEA-0183 Multiplexer which allows to feed the AIS data stream to multiple targets, including services like MarineTraffic and AISHub. Kplex also allows you to setup a NMEA server to distribute AIS to other devices on your network, like for example via WiFi to a navigation app running on an iPad. MUPLEX for Linux and NMEA Router for Windows are a similar tools.

NMEA 0183 option

With the NMEA 0183 option, the dAISy AIS Receiver can directly talk to chart plotters and other marine electronics. In addition, the integrated DC/DC converter allows to power it from your boat's 12-24V power system, removing the need for a USB power source.

For more information and detailed specification of this adapter see the NMEA 0183 / RS-422 Adapter for dAISy product page.

Also check out the 2-channel dAISy 2+ with NMEA 0183 output, which costs only $5 more.

Auxiliary Serial Output

For tinkerers, an auxiliary serial data stream is broken out on the PCB. With a bit of soldering, advanced users can combine dAISy with a Bluetooth module to receive AIS on wireless devices, or connect a data logger like SparkFun OpenLog.

If UART serial communication is all you need, also take a look at the dAISy HAT, which can also run standalone without a Raspberry Pi.

And no, we won't void your warranty for taking a screw driver and soldering iron to dAISy :-)

How dAISy compares

With our open source work, we pioneered a new category of AIS receivers designed around the SiLabs EZRadioPro single chip radio IC. This architecture is instrumental for the very low price, small form factor and low power consumption. The trade-offs are longer acquisition time, lower sensitivity and less range than traditional AIS receivers.

Field tests with conventional dual-channel receivers (like SmartRadio SR162, advanSEA RX-100) showed that dAISy indeed has lower range and is slower to acquire targets. However dAISy clearly outperforms receivers in USB stick form-factor that we've tested so far (Quark-elec, MarineGadget).

Our observation is, that with a good antenna dAISy is well suited to monitor local ship traffic. If you need maximum performance and are willing to pay for it, go with a receiver from the established brands.

Great product!

It's so tiny, but very useful.
I already used it to stream AIS data to online platform like AISHub, Marine traffic and FleetMon.

Stuart | June 1, 2020

I love this thing...only wish i would have bought 2 channel

This Daisy uses multiplexing to serve the 2 channels. They have other units that use 2 simultaneously. I am very happy with the after sales support. I am also happy with the range I am getting since adding a couple elements to my antenna. I have 2 discones but they can't touch a cophased set of dual folded dipoles. My range has gone up a huge amount. They appear to have a low radiation angle which helps it reach out there.

you can see my stats on Marine traffic.

https://www.marinetraffic.com/en/ais/details/stations/4833/_:348c74bd8718f02734aa19324cf25d15

This is simple and sweet and it works. Use AISDispatcher and it makes it a cake walk to put multiple feeds from one dispatcher. I am feeding AIS, Vesselfinder, Myshiptracking, Fleetmon, and MarineTraffic. It doesn't use a lot of bandwidth and its reliable enough to put on a boat.

Excellent AIS receiver

I opted for the self-contained dAISy receiver rather than the Raspberry Pi ‘hat’ on the basis I could transfer the receiver between computers. Delivery was fast and the receiver well packaged. I plugged it in to a MacBook running SkunkTracker and it worked immediately. I shall use that combination when travelling. At home the dAISy is plugged in to a Raspberry Pi v2 running the free rPiAIS software included in the Pi image available from aishub.net. The v2 Pi has no problem running the software. I am receiving AIS signals from distances of 45-50nm via a Diamond X30
2M/70cm amateur radio antenna on my chimney at 10mAGL/80mASL. Overall I am very impressed with the dAISy receiver and have recommended it to others.

Outstanding AIS receiver

THis dAISy receiver is small but compact and has outperformed the RTLSDR# dongle I was using. Very impressive, strong, accurate, reliable. Worth every penny.

Maury | Aug. 14, 2018

Great little Receiver.

Get great AIS reception from this little box connected to lap top. Easy to hook up and quickly ID's boats. Helps spot the shrimp boats in the Gulf before we head out to go fishing.

Klaus | July 2, 2018

Excellent product

I am really happy with this tiny little AIS receiver. There is only one point which could be improved: I have written a software which automatically detects connected receivers like GPS, AIS etc. independent of port and baudrate. This is easy with GPS because GPS sends every second a message even if no satellites are in view. Unfortunately dAISy does not send any message when no AIS message is received. It would be much easier to detect the dAISy port, if at least a state message would be send every 5 seconds. Currently I detect dAISy by sending an ESC character to the available ports to get an answer. But this is not a very safe method because I have to ensure to reset dAISy to receive mode.
Nevertheless an excellent product!

Response from Wegmatt LLC | July 5, 2018

Thank you for your review and feedback. Sending a regular status message is a good idea! I will think about how I can incorporate that into a future version of the firmware.

James | June 27, 2018

Tiny but packs a huge punch

We waffled about buying a dAISy for an upcoming trip. We thought of all the people who don't have AIS reception and figured that we would be fine without spending the extra bit of cash. A friend convinced us to go ahead and pull the trigger with a story about sitting in thick fog with an invisible container ship only half a mile away.

So we went ahead and bought it. It was incredibly easy to hook up to OpenCPN (running on a Chromebook in a Linux environment). The documentation was clear and concise, and we saw ships miles away within minutes. Now, a week into our trip, we've been thankful for the AIS reception on multiple occasions.

A fantastic little device!!

Connected device to my laptop, and fitted a small tuned aerial from London Chartplotters to the dAISy. I stuck the aerial on the sprayhood of the boat. It was a simple configure to set up the usb port on Polar Navy software..... Hey Presto!! Out in the Solent 5NM range... loads of ships, ferrys etc all over the chart!! Weĺl done Adrian and thanks to Steve for advice. I fully endorse this product.

Markus | March 14, 2018

dAISy is perfect with OpenCPN

Hi
I'm running OpenCPN on Raspberry Pi and wanted to get AIS traffic visible.
dAISy was easy to set up .. on linux screen I went to dAISy settings and chose only channel A ..saved settings.
Then new connection ... OpenCPN / connections / new /dev/tty/ACM1 baudrate 38400
and wait some time to get AIS targets visible. At the time of testing I have no proper antenna ... just one meter or about three feet of copper wire as antenna and I can see traffic 11 kilometers away.
Good product .. I will buy another when I need it .. and I will recommend this to a person who is looking AIS receiver.
Cheers ... M.Kantola ...Finland

Jay | March 7, 2018

Awesome device in such a small package!

Connected this little baby to a old magnetic cell antenna, a FME to BNC coupler, the power and hooked it up to a Macbook running OpenCPN. Followed the directions to open a port, and Presto! Up and running in a matter of minutes.

Took it to work on a commercial vessel and used it to keep an eye on things while other mates were on the bridge.

I was so impressed with it that I showed it to others and they placed their orders.

Thank you for such an awesome little device!

Frank | Feb. 20, 2018

Plug and play out of the box - amazing

Great little device that I now use with my Raspberry PI running kplex , a furuno GP32 and a glomex RA201 splitter to get AIS data to my ipad over wifi. Adding the dAISy to this setup was very, very simple. Just adding the /dev/ttyACM0 to the kplex.conf, restart the service and poof.. in business. AIS targets displayed..

Shipping was fairly quick, picked up the package at the post office after 10 days ro so to pay import duties, and documentation was clear. Even an email with additional instructions.

All in all great experience!

Rodrigue | Sept. 12, 2017

nice product

For ais marine configuration with open cpn on raspberry pi3, works very well. Easy installation, no difficult setting required. Only problem is that rpi does not reconize the daisy at each new start. Seems it is not a problem from the daisy but the rpi must be set correctly.
I have recommended this pruduct to a friend who will probably buy one.

Wim | Sept. 11, 2017

Nice compact AIS receiver with low power consumption

Because I live near a important inland canal with a lot of marine traffic, I thought it would be nice to see the activity and not only hear it on my marine scanner. So I hooked the dAISy AIS up to the marine antenne together with the marine scanner and the PC with OpenCPN. Within 15 minutes it was "up and running". I expected a severe reduction of reception, but that was not the case. It works fine.
The final plan is to hook it up to a Raspberry Pi and not switch it off again. My brother has that part working already with dAISy.
The second dAISy unit I bought is for traveling. Not only on our vessel, where we have a class B AIS, but also on trips to the Dutch Islands in the Northsea.
I did not have a real marine antenne in my sutecase, but the small antenne worked well in a range of 5 km, so the harbour and trafficlanes were good visible. And the small unit fits fine in the laptop bag and is smaller than the PC mouse

Gino | Aug. 14, 2017

Ii's a very very nice object

Simply amazing for the reduced size (truly very small, there is only what you need), no trouble at all to make it work: installed on MacBookPro Retina 13", OS X El Capitan 10.11.6.
Used with OpenCPN 4.6.1 Build.
As antenna I used an old antenna of a portable VHF with BNC connector, works perfectly.
Well done, Adrian.

George | Aug. 3, 2017

shipping was amazing. product rocks!

Two day service from Washington Sate to Philadelphia.
Plugged "dAISy" into OpenCPN just using a piece of copper wire for the antenna (guestimate for length for the right VHF band). Displayed 60 AIS targets in Chesapeake Bay off Annapolis.
We won't leave home without it!.
Thanks.

Neil | July 13, 2017

Cheap Insurance

Cheaper option for when going beyond internet coverage. Advantage having small battery drain. Interfaced to OpenCPN well.

Morgan | July 3, 2017

Great device.

Fun to watch ships come out of the fog on AIS and sure enough, here they come. Seems to pick up nearby traffic without difficulty which is what we have it for. Quick and easy to set up.

Christian | June 26, 2017

Stable AIS receiver for practical use

I used the dAISy AIS receiver on a one week blue water sailing trip in the Mediterranean and it served us well. On such endeavors I usually run a LINUX (small) netbook with OpenCPN as chart plotter and automated logbook device collecting and logging all relevant vessel data. With dAISy we've now also got AIS information fed into this system providing as with CPA warnings and all the related amenities.
As antenna I used (as slightly reworked) DVB-T antenna which did its job. My only observation was that the sensitivity of the dAISy based system is somewhat worse compared to a professional VHF based AIS transceiver system. However, you'll still get the CPA alarm in time before the target actually hits you ;-) So, overall this is a clear product recommendation!

Anne | June 16, 2017

Reasonable priced AIS receiver.

I wanted a low cost AIS receiver to hook up to my MacBook while using a chart navigation program. This fit the bill. I just put an antenna from a VHF handheld on it and plugged it in to a usb port. Set up using the baud rate in the included documentation and it worked. So far I have only tried it from inside my house. I live about 3 miles from the water, but still received some AIS transmissions. Obviously it would get better results while on the water with a clear line of sight.

Richard | June 4, 2017

A great, inexpensive passive AIS solution.

The dAISy worked perfectly. I plugged the USB connection into my notebook (into which I also plugged a USB GPS receiver) and I was able to see AIS equipped vessels up to 60 miles away using an active VHF antenna splitter connected to my masthead antenna.

Richard | June 4, 2017

A great, inexpensive passive AIS solution.

Fiona | June 1, 2017

Excelent product

Thank you very much for this amazing low cost product.
Il works immediatly with my openCPN on raspberry pi 3.
As an electronic engineer I would like to tell you : you did a great job, both with electronic, and embed software.
Congratulations !
I Will also write a complete description of openCPN on raspberry with AIS on my blog "fabricolage.fr" (sorry the blog in French).
Thanks again, I wish you the success you deserve with this product.
Fabien.

Great Unit Shipped by USPP not fast

Great unit. infact more than I expected. Worked when plugged into Linux. Service from Tindie and supplier was great just that US Postal Service received on 6 May and it arrived in Australia at my door 30 May. Something must have gone wrong in scheduling. A great pity.

Giulio | May 26, 2017

Very good product at the right price

Very nice product, with a dedicated AIS antenna (1Db) good reception up to 15Nm. Good flexibility due to NMEA and USB.
Documentation can be improved for example on how to mitigate/remove errors (red flashing light) and or antenna selection and placement.

Amazing shipping to Ireland

Jonathan | May 2, 2017

Does exactly what it promises in a robust, compact package

This is a great little device. It delivers on all of its promises without any reservations, and is remarkably sensitive and effective at receiving AIS signals, even with a simple 12" VHF rubber duck antenna. With a 3' whip, it's really great at receiving, and the input comes in standard NMEA strings. It's straightforward to connect with software, and the plain serial interface makes it very easy to verify the device is working properly.

Truly a joy to use.

Garth | April 13, 2017

Excellent product lived up to all expectations

Bought this for my boat, found an inexpensive VHF antenna at Walmart. Installation was easy, only needed a longer USB to miniUSB cable. Tried it out on my first cruise and it integrated with OpenCPN beautifully. Very satisfied.

Masatomo | April 1, 2017

Worked as expected

Using it with Windows 8.1 tablet and opencpn. Needed to install driver as instructed but after that all worked as expected and well. Package arrived at Tokyo quick enough with reasonable shipping cost too.

Lucien | March 26, 2017

Affordable, flexible, and performs well.

I have had an Icom MXA-5000 with a large antenna for a while (to contribute to aishub/marinetraffic/etc), and bought one of these to tinker with. It works very reliably, and gets decent reception, even with a smaller antenna. Configuration was easy, and the built-in signal-strength reporting in the firmware helped optimize the antenna choice and placement. I brought it along on a cruise ship with a small whip antenna & laptop, and it worked even better than expected. I'd heartily recommend it to anyone looking for a compact and affordable solution for non-navigational purposes.

Tomasz | March 20, 2017

Beautiful small device

Just a perfect small device to receive AIS . Runs w/o any problems on Windows 10 (serial driver installs automatically). For tests I run it with a simplest indoor VHF antenna - and device is sensitive enough to catch ships even if antenna location is far from being perfect.

Gerrit | March 15, 2017

Tiny, cheap and functional!

IT works, enough for my purpouse, simple, cheap, tiny,
Use my spare VHF aerial on the heck of my yacht

Alan | Feb. 26, 2017

Fast delivery to Oz, Plugged it in and worked really well

I connected the dAISy to a piece of co-ax with a crude dipole made by splitting the end of the co-ax by 44cm. I plugged it in to my OpenCPN laptop at work with the antenna stickytaped to the window. I was able to pick up ships from Melbourne CBD all the way to Port Philip bay.
All I had to do in the laptop was to add a NMEA comms link to /dev/ttyACM0

Daniel | Feb. 21, 2017

Highly functional, versatile device with excellent support

I got a dAISy receiver for tracking ship tracking while sailing in congested shipping lanes, for boat-spotting when I can't be on the water, and for experimenting with instrumentation. The device was delivered quickly and appears very well made. The vendor is very responsive and takes an affirmative interest in making sure his customers are satisfied.

The standard USB interface was readily accessed out of the box by OpenCPN. There is a simple but effective interface for tweaking settings. I do not have objective measurements but the sensitivity seems quite good, easily enough for my purposes. I do not have line of sight to the water from my home, but am able to pick up vessels >4 miles away over a hilly urban landscape. On the water I expect it will be significantly greater.

In addition, the dAISy has internal pins for serial communication, e.g. with networked SBCs and microcontrollers. Examples of networking using Raspberry Pis and ESP8266 microcontroller (via the Arduino IDE) are linked from the vendor's site. I prefer micropython, and it was straightforward from these examples and the other documentation to multicast AIS data from the dAISy wirelessly to multiple laptops running OpenCPN via a $10 ESP8266 microcontroller running micropython. A fun learning experience, and possibly some utility at sea.

Overall, I am very happy with this purchase and would recommend it to others.

Michael | Feb. 1, 2017

I am truly impressed with the dAISy

I am truly impressed with the dAISy. The install was almost plug and play. I'm using a 4 inch BNC VHF 136-173MHz Antenna and running Open CPN on an older Dell lap top upgraded to WIN-10. Win-10 detected the new hardware and assigned a COM port. In Open CPN I did have to add a connection and change the baud rate, but as soon as I hit "OK" the AIS targets with speed/direction vectors and ship data appeared.

My only caution is that the dAISy has to be plugged into the USB where it was discovered (or add a new COM). The setting I used are: Filter NMEA Course and Speed data, Filter Period (1 sec), Serial, COM7, Priority 1, 9600 baud, Filters In None, Filters Out None, Protocol NMEA 0183, and Control Checksum.

Thx
Mike in Seattle

Gerald | Jan. 23, 2017

Ça marche !

J'ai installé le "driver" pour OpenCPN. Connecté une antenne VHF (2017-01-23). Connecté le dAISy à mon PC et voila. Les bateaux du port de Trois-Rivieres sur le fleuve St-Laurent sont apparus avec leur info MMSI.
Still to test is the connection with my Garmin 542 GPS map. Next summer...

Meaghan | Jan. 5, 2017

I Don't Really Know...

Bought this as a gift. My boyfriend LOVES it. I have no clue about it. He asked for this specifically and had great things to say about the company.

With my experience I received such great service. Communication with seller was above and beyond. Shipping was incredible. I was stuck with days until Christmas and needed this as a last minute gift when my gift was back ordered a month later from another company.

Seller also touched base with us to let us know he shipped and then later to follow up if we needed help with the item.

I absolutely recommend this seller. I absolutely recommend this product based on my boyfriend's interest and use with it. I cannot tell you anything about he actual item though.

Cheapest USB AIS receiver I have found and it works

I wanted an AIS receiver to use with OpenCPN. I tried a software defined radio (SDR) USB stick but getting it to work was pretty fiddly. The dAISy does all the signal processing and passes NMEA messages to the computer's USB port, so you don't have to fiddle with signal processing software on your computer. Plug it in and AIS targets appear on your OpenCPN chart display.

Well, almost. The dAISy isn't the most sensitive VHF receiver so it requires a good antenna. I started with a 1/2 wave wire whip. I didn't get enough AIS messages to show up on the screen. I did get a few, according to the light on the dAISy, but there were way more messages with errors than complete messages. I ordered a 6bd gain VHF antenna and an SO-39 to BNC connector and that immediately solved the problem.

The dAISy is receive only, so you won't appear on other vessels' AIS displays. Consequently, you lose a lot of the advantage of having AIS, but it is nice to be notified of commercial shipping nearby. If you are interested in AIS and want to try it out with a small investment dAISy is the best way I've found. With the antenna, connectors, and the dAISy my investment is less than $100.

A USB SDR stick is a lot cheaper but setting it up isn't nearly as simple.

James L | Oct. 31, 2016

Excellent product for a reasonable price

The dAISy does exactly what it is supposed to do. I also got the adapter for my marine antenna. Installation is super easy with Win10. Just plugged it into my antenna and PC with OpenCPN. Go into OpenCPN, Tools, Connections, and my computer recognized dAISy on Com4. Enter the settings recommended in the dAISy documentation. I think the printed documentation had a web address mistake, but I just went to the home page and quickly found what I needed. Adrian followed up with an email offering help and answered a question for me regarding antennas. BTW, he told me don't use your VHF radio antenna with a splitter, it will damage dAISy. I knew this but checked with him just in case I was wrong. I hooked up dAISy to an aft rail mounted 38" antenna and it works fine. My VHF antenna is mounted atop my mast... Now I only wish Adrian would make a reasonably priced AIS Transponder.

Leo | Oct. 22, 2016

A very well made AIS receiver backed by great service !

As a boater I operate a class A AIS transponder and I use the dAISy to keep a lookout for it. Distance is 18nM over built-up land from the marina to my home and the dAISy has no problem with receiving my boats' data. Service by Wegmatt is great ! I recommend this nifty little receiver to anyone.

Kurt Jon | Oct. 20, 2016

Simple, elegant, well-presented, well-supported.

A painless way for us to add AIS information to our round-the-clock watches. dAISy fills a niche for boat people who don't want to be fully tricked-out at great expense, but appreciate modern aids to safe navigation. We're using OpenCPN on a choice of Navigatrix (Linux), LinuxMint and MacOSX platforms. Our yacht is a 12m schooner in New Zealand and the South Pacific. Thanks, Adrian.

Arif | Oct. 12, 2016

Great product

Well made product that functions exactly as described. Very easy setup with Linux and Raspberry Pi 3.

Michał | Oct. 7, 2016

I sincerely recommend for charter boats

I have tested the device over 2 weeks. It works flawlessly. My setup consisted of a laptop, 10 meters of antenna cable and 1m antenna monted at the back of the yacht. With such a setup I was able to detect AIS signals from ships from up to 25nm (AFAIR record ship-based AIS signal received was 24.8 miles). I have tested and it works with both MaxSea Time Zero and with OpenCPN.

The device itself is plug-an-play, as easy to install as a GPS dongle. I sincerely recommend it for charter boats, as it is really portable.

Magnus | Sept. 27, 2016

Very good product to an amazing price.

Very good product, does exactly what it is supposed to do.
Documentation is good and the support (actually none needed) is great.

Jim | Sept. 9, 2016

Super product; super value; and simply outstanding support

Needed a low-cost AIS receiver (to display on either Polar Navy or OpenCPN downloadable marine chart plotters), and the dAISy AIS turned out to be exactly what I needed and at a very affordable price. Mailing costs were very reasonable and the unit was shipped, and received, quickly. An enclosed "quick start" guide and a downloadable "Users Manual" were added plusses. Difficulties I experienced in buying a suitable (read low-cost) antenna and configuring the unit with both of the aforementioned applications (because I'm an old guy and not tech savvy) were immediately resolved through solid recommendations and easy-to-follow instructions.

William | Sept. 9, 2016

Terrific product.

This worked perfectly from the get go, was very easy to set up and takes up almost no room inside the dash. The guy who makes these is really responsive and great to deal with. Highly recommend! Hope he can come up with a transceiver version soon, I'll take two more the day they're ready.

Philip | Aug. 30, 2016

Excellent

This small AIS unit is very impressive. Out performs a more expensive unit I have. Easy setup and with helpful instructions .

Jonathan | July 30, 2016

Faultless

Installing in a yacht with a coaxial switch on the vhf aerial. Requires a few adapter plugs which would be great to order with the unit.

Mr Lee | July 15, 2016

Excellent AIS RECEIVER

Great little device. Works excellent. Great support in all aspects from supplier. Thank you very much!

Stuart | July 12, 2016

Amazing little receiver

Works very well. So tiny that I put a weather-proof UHF connector on the bulkhead (for the antenna connection) and plugged in the unit with a double male UHF connector. Power is via the provided USB cable, so no extra wiring needed. The receiver is smaller than the plugs and sockets! I am using it with OpenCPN and it was an easy set up. You need to search some webpages to find extra detail if you want it, but provided the com port is set up correctly, you will have a great little reciever for a fraction of the price of other units.

Good receiver for sports boat

I'm using it in a sailing vessel like a second AIS on PC and it's really easy to instal in Windows 10 and OpenCpn, without any drivers. The product meets very well with what I expected of it and it's highly recommended. Thanks for your attention.

Dmitry | June 21, 2016

Excellent product, good shipping!

With "Monopole + 2 Radials antenna" made of 10mm aluminium tubes like from this article - http://rtlsdr4everyone.blogspot.ru/p/ais-antennas.html I got AIS signals - 14 miles distance from moving ships, 28 miles from 30 metres ground beacon. Shipping to Russia also was fast. Seamless work with OpenCPN under Linux. Thank you for a good product and service.

Richard | June 7, 2016

Excellent product, good value.

An AIS receiver that fits in the palm of your hand for less that $100, what a deal. With a decent antenna it preforms quite well. No driver bugs or issues. I've used it with shipplotter and OpenCPN. Prompt shipping and good customer service.

Works as expected

Works with most small computer dev boards out of the box. I had some trouble with an OrangePi not having the correct kernel modules but RaspberryPi and Udoo Neo work great.

Amado | May 21, 2016

Plug it in! It just works!

Unmentioned in the description: Unit comes with a mounting plate (so *you* don't have to fabricate one), and comes with the appropriate USB cable.

Plug it in. Configure OpenCPN. Within seconds, using nothing more than a marine VHF antenna, you'll receive your first AIS broadcast. It's just that simple.

At our location, it receives every ship that an iCom MXA-5000 receives for 5 times less money!

Shipping was lightning fast. The documentation is a simple one pager describing how to configure your AIS software.

The communication was great. Really responsive.

SDRs are changing the economics in the AIS space. dAISy is an exemplary product in this regard.

Response from Wegmatt LLC | May 21, 2016

Thank you for your review.

Unfortunately, I no longer include mounting plates as they are no longer available from the vendor of the enclosure. dAISy now comes with Velcro tape for mounting. Not as sturdy as screwing it down, but sufficient in most cases.

5 stars for dAISy receiver

The item was delivered without any delay in Spain just one week after I bought it.
After ordering, I received the confirmation and tracking number, and also a personal mail from Adrian Studer with the instructions for installation and use as also an invitation to contact him if any problems, what I call great service!!
I connected the dAISy receiver as soon as it arrived to an old windows laptop with openCPN, and after some simple configuration (windows driver and serial port config) I got with my approx. 90 cm homemade dipole 162 MHz antenna following results:
- 2.5 miles from the cost at a height of about 60 meters (200 feet) to sea level I received AIS ships up to more than 150 nautical miles away (I do not understand how this is possible with such a small receiver….!!)
- At sea level with the antenna about 3 m ( 10 feet) height I received ships up to about 50 miles away, this is “far better” than what I expected
I will continue testing it, also with my android devices, but at the moment I am more than positively surprised, therefor 5 stars over the whole line for this small AIS receiver, the price, the very good receiving capacity and the aftersales service which is offered by Adrian Studer make it for me and my 32 ft sailboat the absolute number one and “must have”!
Thanks again and many greetings from Spain. Marc

AIS receiver, Tested with Rasberry Pi & Open Plotter/CPN

The package arrived sooner than promised. It is a TINY device. I have an older AIS receiver, but I wanted something more compact with a usb connection. I have not used it for actual navigation yet, simply waiting for warmer weather.
I have connected the device to a couple antennae, results weren't always consistent. on my first attempt, I had cable strung across the room from the large monitor and RPi, to a substanial antenna on my roof. (Cushcraft ARX-2) The antenna is tuned for 146 Mhz, but is ok for receiving AIS frequencies. I was able to receive signals from a decent distance. Second try, The RPi had a LCD connected directly to it, and I heard fewer stations.
SO, I was worried that the compact package was causing interference, and I systematically tried different combinations.
By checking the number and distance of stations, I am completely satisfied with the reception . With the house mounted Antenna, I heard ships in baltimore Harbor, about 10 miles away, Aids to navigation as much as 45 miles away, and class B vessals about 5 mile away.

I tested from my boat, and heard MORE stations, Including a few Aids to Navigation in the Delaware Bay (I'm In the Chesapeake bay.)
I have the luxury of a second antenna on my boat, on a second mast. I am able to see targets a little over 45 miles away. I suggest you use an antenna dedicated to the AIS receiver, as all splitters or switches or other devices have some signal loss. Yes, the more expensive active switch can be used, but a simple TEE in your VHF antenna line cannot.

In Summary, with a decent antenna, results are good, and interference with other electronic equipment was NOT a problem.

André | April 30, 2016

Works within one minute!

Aangesloten op mijn Windows 10 laptop met Navigo en het werkt direct!
Works directly with Windows 10 and Navigo navigation system. Perfect!

Murat | April 20, 2016

55 nM range ! It is amazing...

I installed a 1 meter VHF anthen on pushpit ( totaly the heigh of anthen from water level is 2-3 meters ) . I used "RG-213/U coaxial 50 ohm" cable ( 6 meters long ) . My cable insulation was away from other electrical cables and the connectors on both end was installed carrefully by myself . I am using OpenCPN software on a small computer. No need any extra driver installation on windows10. And the result is amazing ; i can watch any vessel with ais transponder up to 55 nM away. Many thanks to all of you who create this product. Regards.

Michael | April 19, 2016

Cute little AIS receiver

This little gadget is an absolute necessity for the navigator. Compatible with e.g. OpenCPN and other navigation programs that understand the AIS NMEA strings. I can surely recommend it to anyone having an interest in 'seeing where the ships are'. You might consider setting up your own monitor station for MarineTraffic.com.

Anatoly | April 17, 2016

An amazing product

I wish to thank you for the opportunity to easily get a device that simplifies the install of AIS, providing low cost safely alternative to the boating community. I highly recommend it for anyone, for ease of use, installation and nice view.

I would note an excellent and prompt communication with a personal touch from Adrian, I wish the best to all his development plans!

Norleif | April 12, 2016

Handy little device

I got two units to monitor both channels at once. I need this functionality for some R&D work I'm doing.
I'll be first in line to buy a dual RX version.
Sensitivity is not great, but that doesn't matter for my use-case.

Sean | April 11, 2016

Fantastic Product

I'm building an AIS setup for my boat and this product has been excellent. Well documented, extremely professional quality build. I can't recommend it enough.

Mikko | April 11, 2016

dAISy is working well

It seems to work very well in my environment. I tested it on PC and I just ordered the NMEA0183 / RS-422 -interface for it. I will install it to my boat to be used with a Lowrance chart plotter. Thanks for the good product!

Mitsuharu | April 2, 2016

dAISy tracks Base Station 7 miles over industrial area

I ordered 2 dAISy receivers which arrived this morning on schedule after processing for a week in Belgian Customs and both units have passed the initial test.
From a location close to the Capital using an old TV top box extensible balanced dipole antenna with only 1 element primitively connected to the BNC center tap with a test cord both units picked up a Base Station (MMSI 205510990) situated on a Canal about 7 miles away overland across Brussels International Airport and an industrial area.

Still have to find an OpenCPN compatible Chart for the Canal, but GOOGLE Earth shows the Location is spot on.

I can’t wait to see the tracks when I get back to the coast in southern Sri Lanka, and can definitely recommend this device.

Peter | Feb. 28, 2016

Works, first try

I have not tried in a boat but took my laptop with OpenCPN and tested it in a harbour and received AIS info as expected. Thanks!

Jacob | Feb. 27, 2016

Perfect apparaat, precies wat ik zocht.

Deze ontvanger doet precies wat het moet doen, is klein en maar een paar tientjes duurder als de DVB-T stick oplossing.
Ben er heel gelukkig mee.

Carole | Feb. 14, 2016

Useful unit

Coupled to my Android tablet seamlessly and operated well. I was not able to load the driver to an old Windows 7 PC, but that is probably the PC!
A useful device for busy waterways.

Pierre | Feb. 10, 2016

Great device

I did not try it on my boat yet since it is winter. However, as a test, I connected an antenna from an old portable VHF I had laying around for years. I then took my tablet with Windows 10 and OpenCPN installed, drove by the harbor, plugged the dAISy in with the USB cable provided and "Bingo". Within seconds, all the ships in the harbor appeared with all their specs on the screen. Can't wait to try it on my boat.

Ian | Jan. 28, 2016

Affordable AIS at last

I have been looking for a reasonably priced AIS receiver to use with my laptop for some time, and just found this. I took it to our sailing club to test it using their VHF aerial, and was really pleased to be able to configure it easily on both OpenCPN and Polar Navy navigation software. It picks up vessels well out of sight on a shortish antenna. Apart from the low cost, being powered by USB is a big plus for me as I don't need another power supply. It is also very small, I intend to tape it to my laptop lid when in use.

Jan Frode | Jan. 28, 2016

lovely product

After opening package and with a short readup from manual and user forums I had this little beaty up and running and set up with a home made vertical antenna and receiving and decoding consistently both class A and B data from upto 40 nautical miles from my veranda.

Data receive I could easily upload and share with Marinetraffic and AIShub.

Both AIShub and Marinetraffic gives you detailed reports on your performance and from monitoring these over few days these I can say the dAISy meet all my expectations.

The green and red LED blinker also gives you immediate feedback on activity and on how well you receive.

Recommending this to all for leisure boat use and home AIS receiver stations.

Great for covering those "blind spots" in your local AIS coverage.

best regards jan

Martin | Jan. 25, 2016

Also works with Boat Beacon app on Android Phone / Tablet

Very Convenient. Plug and Play...just what I was looking for and that at an affordable price. I got it working with OPENCPN on my laptop
But also on my Android Phone with the Boat Beacon app. https://play.google.com/store/apps/details?id=com.electricpocket.boatbeacon&hl=nl
My Phone provides power to the dAISy through an OTG cable. So it runs without an external power supply . It couldn't be simpler.
I had an old VHF antenna placed indoors by the window and was surprised to pick up boats approx 6 nautical miles away. That is with land trees in between.

I highly recommend Adrians dAISy!!

Jean | Jan. 21, 2016

Cheers

Hans | Jan. 5, 2016

Works good

I use the ais receiver in combination with a raspberry pi 2. The set up was easy. It all works fine with the open source software opencpn. I use a simple homemade dipole antenna.

Mobico Shipping As | Dec. 17, 2015

Simple and excelent

I'm using this with Ubuntu 14.04 and 15.10 also tested. Works like a charm. The USB cable shipped is unreliable and should be replaced with a better cable,,,,
Some articles can be found on the net. First it seemed a little confusing if the default serial speed was set to 9600 or 38400 because since some articles describe 9600 baud and other describe 38400 - it sorted out that the default was 38400 baud.

Eric | Dec. 10, 2015

Just one problem : the usb cable did not work...

I have bought the daisy Ais recever and at the beginning, I have not been able to make it work at all.
I spent a lot of time to figure out why no data ais targets were detected.
I finally replaced the usb cable that was shipped with daisy ais by another one (longer), and it worked a charm.
I'm happy now !
This is the reason why i put 4 stars on the product instead of 5 ;)

Response from Wegmatt LLC | Dec. 10, 2015

I apologize for the inconvenience and wasted time on your side. The 4 star rating is very generous under those circumstances.

As this is not the first failure of the included USB cable, I started looking for a new supplier. In the meantime I will make sure to test each included USB cables before shipping.

Thank you,
Adrian

Thorbjörn | Dec. 6, 2015

Test of dAISy

I just tested dAISy and when using windows 10 on a lap top and also Ubuntu on a raspberry pi 2 it was just to connect the USB cable to a USB port and it just worked. I use openCPN to test the AIS functionality.

Wilfried | Dec. 5, 2015

such a affordable product I have long been looking for

Hi I am recreational boat owner and hobby fisherman . We live in the Southwest Netherlands , Zeeland.
We sail in dangerous tidal waters with lots and lots of shipping , the largest container ships in the world are passing at our doorstep.
To improve the safety on the waterways in general, our government provides all boaters with accurate downloadable maps in ENC format for free. Those marine charts can be displayed with the use of OPENCPN software and any GPS receiver. We install it on refurbished netbooks and small notebooks like Acer aspire one having the Win7 platform as operating system.
The OPENCPN chart plotting software can also handle AIS data: Heading and speed of surrounding vessels, positions tracking, Real-time ship locations, port arrivals and departures.
The dAISy AIS receiver is capable of capturing all this and display it on screen to you, improving safety at the helm, for passengers and crew.
It's easy to install, and doesn't need any external power-line! The USB connection only is bringing the receiver to life. A small BNC "rubber duck" antennae will catch the AIS signals transmitted by nearby ships for you.
Note: This product has to be used as an addition to your marine safety package, always keep watch and listen for signals and radio traffic. Use your radar if you have one, keep eyes on the gauges and depth sounder. Do never rely solely on any AIS device when crossing the estuary shipping lanes, coastal travel or on high sea voyage.

Aedan | Nov. 15, 2015

Works beautifully

It seems to work very well. I've only been able to try it in hotel so far, with an antenna hanging out the window. Within seconds was picking up all the same targets as the local marinetraffic station. Overall I'm impressed and it's great value.

Curt | Nov. 12, 2015

dAISy Receiver

I purchased the dAISy Receiver and combined it with a Raspberry PI2 computer running the chart program OpenCPN. I am utilizing this equipment as a secondary chart plotter and AIS receiver on my sailboat. I connected the dAISy to my VHF-FM antenna via a splitter. This connection shares the same antenna with my Standard Horizon GX 2150 VHF-FM radio which has AIS built into it. My VHF-FM radio is networked to a Raymarine chart plotter that receives AIS data from the Standard Horizon radio. So far I have seen no loss of signal on either unit and while sitting on the Columbia River in Portland Oregon I get excellent AIS input from the dAISy into my Raspberry PI.

dAISy AIS Receiver

DAISy AIS Receiver is easy to plug to OpenCpn. I plug on it a portable VHF antenna ( no installation :) and it works find inside my 43' Beneteau. My next test will be with my Masted Antenna to see the difference before to install a second VHF antenna. I' m very happy with this product and recommend it. Finally an AIS receiver at reasonable price.

Response from Wegmatt LLC | Nov. 9, 2015

Thank you for your review. Be careful when connecting the AIS receiver to the same antenna as your VHF radio. Unless you antenna splitter specifically prevents back-feeding to the receiver, the AIS receiver might get damaged when a strong VHF radio transmits on the same line.

Dave | Nov. 6, 2015

Better than expected performance

I consistently get 50 mile range over hilly terrain and 180 or more messages per minute with a dipole antenna taped to my office window. If you want to do something a bit unusual the documentation is a bit weak and scattered (I have an ESP8266 attached to the internal port which makes it standalone), but the store owner is super responsive and helped me get it working. It's a great product for the price.

Edit: The new website with Quick Start Guide and Users' Manual put the documentation in one spot and address the weaknesses in documentation.

John | Nov. 5, 2015

It is working perfectly with Linux Mint 17.2 and OpenCPN

I use it with OpenCPN 4.0.0 on Linux Mint Cinnamon 17.2 64 bit.
It took me less than 5 minutes to cut away one end of a bnc-cable and connect it to two pieces of copper wire to build an antenna. Once connected I pointed OpenCPN to the device file (/dev/ttyACM0) and its map was immediately filled with targets.

It is small, cheap, efficient and totally problem free.
I love it!

Matthew | Sept. 7, 2015

dAISyy rocks

This is what I was waiting for! Small size and good reception. Perfect for my projects! Make sure to get the right antenna. Only get one that is AIS compatible.

Frederick | Aug. 12, 2015

Easy and Reliable AIS Receiver

This dedicated AIS channel receiver is very easy to use and the drivers are quite reliable and connect easily.
This is a simpler way of getting AIS than the less expensive rtl-dsr dongles and with a good antenna can take the place of more expensive equipment on a small boat. I've used it on Windows 7, 8.1, and 10. The driver install readily for 7 and for 8.1 you need to trick windows because it is unsigned. Adrian has excellent documentation for this short process which only needs to be done once and. for Windows 10 there is no special driver required,

You will not be disappointed.

9/26/2015 Adrian has updated the programming and following his instructions I have updated my dAISy and have just had a chance to test it. It is much more sensitive now and seems to be getting ship contacts more quickly and over a greater range. I have not yet tested this on the water, but from a 1st floor location behind trees, we are getting more contacts that are also further out! I have no doubt that this receiver will be even better now. Thank you Adrian.

10/8/2015 Using VHF antenna at top of 36' mast picked up ships 7-12 miles away. Inside Block Island Great Salt Pond, picked up ships to the Southeast 8 miles away and saw all the ferries coming from Point Judith 11 miles away.

Rene | Aug. 4, 2015

Great product for a good price

I bought the product in order to setup my own AIS-receiver station.

It was only a matter of 20-30 minutes in order to have the product connected, software installed and receiving the initial AIS data.

Meanwhile I asked for some additonal information concerning AIS-data in general and there Adrian provide me with a prompt and good reply.
I don't expect that you need help with the setup, but it's good to know that Adrian is there when having any questions.

When you intend to buy an AIS receiver I could really recommend the "daisy".

Manfred | July 24, 2015

Elegant, simple, compact and very usefull

My goal for utilizing dAISy is enhancing safety a little bit on my small sailing vessel. I'm a passionated coastal sailor wit an Etap 22i. Sailing quite often solo on Ijsselmeer and Waddensea in The Netherlands. This spring I finally decided to deploy an autopilot after years of doubting. At the same time mine Garmin GPSmap and the very old Autohelm Tridata ST50+ instrument are not that solidly working anymore. So I decided to design an integrated Marine Instrument & Display Controller, where an AIS receiver would be fit in.

The design which is mainly based on open source software (Ubuntu/OpenCPN) and (semi) open source hardware (RPI/Arduino) has been finalised more or less. Now I started with the building blocks to assemble and evaluate. dAISy was my favourite one based an de specs I could read. In the last 2 weeks I installed it on my sail boat to get it evaluated in a "living lab". And I'm confident with what I've got from Adrian. The product works like a charm. I evaluated it on both Ubuntu (15.4) and Windows 8.1 and OpenCPN 4.0.0.

The only thing which might need some attention is the "marine data collection time". That's the time required to get the list of AIS object visible in OpenCPN. That took a considerable amount time (> 10 mintutes) to get 36 vessels around me.

Nevertheless, so far so good. I can recommend this fine elegant of hardware/software specifically if you're looking for a high price performance. dAISy helps me building up the integrated Marine Instrument & Display Controller I've got in mind.

I think Adrian did an excellent job. Thanks for that.
