Have you looked into using gyros for north-finding? There's been a lot of progress in recent years with MEMS gyros (which normally have too much zero-drift to work with traditional gyro north-finding techniques).
See, for example: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5464685/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5464685/
- karmicthreat 7y agoThat's a pretty neat technique. It seems superficially similar to how mems magnetometers work. The size and oscillation make me question how robust that is though. One stop gap solution I has was just an IR beacon on my GPS base station. I got an initial alignment with the rover camera and my two gps points. But ended up adding a second gps to the rover.
