Flight Test Betaflight 4.4 GPS Rescue
2 years ago
4
Flight testing Betaflight 4.4's enhanced GPS Rescue feature, with the new ability to make a controlled landing and disarm.
The GPS module is a Beitan BN220 in NMEA mode. It's supposed to support UBLOX but I couldn't get it to work (I suspect a broken Rx line in the wiring harness). Instead I used an FTDI adapter and UBLOX U-Center software to program the GPS module to report position at 10Hz. The default for this module is 1Hz which is not fast enough for good performance with GPS Rescue.
The flight was a great success, landing less than 2 meters from the landing pad in quite windy ( 20+ mph) conditions.
Good job Betaflight Devs!
