gpsd daemon differential-gps get heading

Is it possible to get heading information using gpsd and a differential-gps device?

I'm seeing the raw serial messages with the format below coming though, however on the default gpsd port I'm not seeing any heading values.

Raw serial:

$HEHDT,264.69,T*10

TCP port:

{"class":"TPV","tag":"GGA","device":"/dev/serial/by-id/usb-FTDI_USB-RS232_Cable_FTU98S5G-if00-port0","mode":3,"lat":41.408677538,"lon":-132.105521583,"alt":14.460}

Looking in the gpsd man pages I don't see any flags which could help decode these strings. Wondering if its even possible?

Using a python/command line package called gpsd will decode it for you. Run sudo apt-get install gpsd gpsd-clients python-gps and it will install that package. Read this manual page by adafruit to help you use it. https://learn.adafruit.com/adafruit-ultimate-gps-on-the-raspberry-pi/setting-everything-up
