I have a fixed base station (SIRIUS XXL) and a rover (TinyRTK) that can go to FIXED within 2 minutes, but I can’t seem to get a reading for the heading of vehicle. I only get the heading of motion while my vehicle heading according to UBX-NAV-PVT is always “n/a”. I know that one way I can calculate the heading of vehicle is if I have 2 antennae, but I think I should be getting a heading of vehicle by just configuring the base and rover somehow. I send rtk corrections over ntrip and I’ve been able to get a FIXED from my current configurations. What other configuration parameters should I be looking at?
