The ME31GR01 is a single-frequency, full-constellation GNSS module.

Its multi-constellation RF front-end architecture enables simultaneous reception from all four major GNSS constellations (GPS, Beidou, Glonass, and Galileo), with support for QZSS and SBAS satellites.

This provides the receiver with excellent sensitivity and acquisition capabilities.

The module's superior interference suppression characteristics ensure reliable positioning even in challenging signal conditions.

The multi-constellation combination significantly increases the number of visible satellites when navigating in dense urban canyons, reduces the time to first fix (TTFF), and improves positioning accuracy, enabling precise location tracking even in harsh environments.
