GPS-RTK Dead Reckoning Azimuth Extraction

Hello,

I’m using SparkFun GPS-RTK Dead Reckoning pHAT for Raspberry Pi (https://www.sparkfun.com/products/16475) connected to a Raspberry Pi 4 and a GPS antenna but I’m unable to extract a valid azimuth (relative to north) reading.

I’m looking at the NMEA GPGSV message and also the Python “headMot” API (https://github.com/sparkfun/Qwiic_Ublox … rds_ex1.py) but each one of them provides a constant number that doesn’t change when the board is in motion / changes its direction.

Is there any required configuration of the board to extract a valid reading?

Thank you
