Matek AP_Periph GNSS GPS M10-L4-3100
by Matek Systems

• M10-L4-3100 is based on ArudPilots’ AP_Periph firmware,  It is a GNSS+COMPASS+BAROMETER peripheral with CAN/DroneCAN and UART/MSP interfaces.
• M10-L4-3100 uses multi-constellation GNSS powered by u-blox M10 series , It is a concurrent GNSS receiver which can receive and track multiple GNSS systems. Owing to the multi-band RF front-end architecture all four major GNSS constellations, GPS,Galileo, GLONASS and BeiDou can be received concurrently.
• M10-L4-3100 integrates an industrial-grade compass PNI RM3100 which provides high resolution, low power consumption, no hysteresis, large dynamic range, and high sampling rates.

Tips and Notes

• on M10-F4-3100, The 3 magnetic coils have little solder paste to avoid the excess to “tilt” them, resulting in some reading inaccuracies of the compass. Any strong impacts will definitely separate them, especially the “tall coil” Sen-Z-f.  Pls use this precision module with care.
• The default configuration on GNSS module with ublox FW5.1 is concurrent reception of GPS, Galileo, and BeiDou B1I with QZSS and SBAS enabled.  GLONASS is disabled by default.
• Beidou B1I (1561.098 MHz) and GLONASS can’t be enabled at the same time.  Beidou B1C (1575.42 MHz) and GLONASS can be enabled at the same time. Flight controller firmware(INAV, Betaflight, ArduPilot) don’t support enable Beidou B1C for now.  
• with GPS, Galileo, and BeiDou B1I with QZSS and SBAS enabled, M10 GNSS module can receive more than 30 Sats with HDOP down to 0.55.
• Start with u-blox GNSS FW3.01, timepulse is aligned with UTC time and that time is set valid only after leap second is downloaded. That could take up to 12.5 min. Probably PPS LED will not blink immediately after GPS has 3D fixed.
