    Tbh that sounds like a fun project for an app or something, as a backup to gps in case it’s jammed. Just lay your phone on the ground, take a long exposure picture and then use the phones time to calculate where you are. Might need to take the accelerometer into account if the ground isn’t flat.

      Fighter jets have automatic star navigation to augment their GPS navigation features. It’s more than a fun project, it’s military technology.
