What is it?

A combination GPS and magnetometer for small unmanned aircraft. Includes a uBlox SAM-M8Q integrated multi-constellation GNSS unit and a high-quality Memsic MMC5983MA magnetometer enabling sub-1-degree heading accuracy. All of this interfaces to your autopilot via robust UAVCAN interface - no sketchy I2C wiring for your magnetometer! Comes fully assembled, ready to plug in and use!

What makes it special?

• Extremely high-quality Memsic magnetometer IC allows ~0.5deg heading accuracy in low-interference installations
• uBlox multi-constellation GPS provides excellent performance in any flying scenario
• Robust UAVCAN interface is compatible with most Pixhawks and similar autopilots and makes it safe to install this out in a wing or wherever is convenient!
• Broken-out GPS interrupt pin for special timing applications
• Drop-in replacement for competitive UAVCAN GPS/magnetometer unit
• Update firmware via CAN interface

Why did you make it?

Stock GPS "pucks" include a magnetometer that interfaces to the autopilot via I2C, which is a board-level interface - it should never be used for long-distance communications. This makes it difficult and dangerous to mount your GPS/mag anywhere far away from your autopilot, so you can't really get it far away from power sources and other interference that messes up your heading measurement! Another manufacturer makes a similar device, but quality issues with those boards prompted us to make a drop-in replacement.
