GPS module used by 3DR
It comes an idea of using 3DR gps module for other applicaiton, but few things need to knowL: 1. it's not a NEMA one, the one I have iswith ublox chip, 6 or 7, by default,it communicates through uart at 38400bps, and it use an other portocol UBX, which is an binary one. different chip has different config file: https://github.com/ArduPilot/ardupilot/tree/master/libraries/AP_GPS/config it can be loaded to gps by uusing u-center from ublox https://www.u-blox.com/en/product/u-center-windows the config used by 3DR has majorly following out put in UBX 00:08:24 R -> UBX NAV-SOL, Size 60, 'Navigation Solution' 00:08:24 R -> UBX NAV-SVINFO, Size 208, 'Satellite Status and Information' 00:08:24 R -> UBX NAV-STATUS, Size 24, 'Navigation Status' 00:08:24 R -> UBX NAV-POSLLH, Size 36, 'Geodetic Position' 00:08:24 R -> UBX NAV-VELNED, Size 44, 'Velocity in WGS...
