Turns out I was calibrating the accelerometer and compass correctly. Same as I used to do in my drone building days.
I must have had a bad external GPS antenna because the GPS never connected to a satellite when using it.
I went back to Amazon and bought a Garmin marine GPS antenna and am really happy with the performance. Even inside my house, the OP GPS will lock onto 12 satellites within seconds, then bounces around between 8-12. Outside is even even better. I was a little worried that this antenna would be compatible, but turns out it is.
