NMEA YAW Input
in order to use it (in Simulation):
EK3_SRC1_YAW 2
GPS_TYPE 5
SIM_GPS_TYPE 5
Does it work with GPHDT alone? I don't think so. The GPS will not be considered "Healthy" in order for it to be consumed.
autotest PR with GPS that provides GPHDT
To test it with BlueOS and Navigator:
SERIAL2_PROTOCOL to GPS
GPS_TYPE to NMEA
