Making fun for STILL using it. If our navy would navigate by the stars at night, it would be laughed at, right? And rightly so. ;)

GPS can be jammed, try jamming stars.

Now I wonder if we could launch satellites as artificial stars for celestial navigation. Basically optical GPS.

Starlink: hold my Xitter handle

Actually, don't. The pollution would kill us all.

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.
