There is lots of software that can display what the sky should look like at any given time and terrestrial location. I have also heard that spacecraft determine their position based on pictures they take and then matching stars to it, called star tracking as far as I was able to find.
Essentially what I am looking for is a star tracker like on space craft, but on earth. Is there a word for that? When looking for "star tracker app" or "star tracking smartphone", I get software that overlays the sky over the camera feed based on a wonky internal compass (not matching stars in the camera feed) or hardware that controls a telescope (I'm not looking for hardware controls). The device location and time can be determined with GPS, the only unknown is the direction the camera is facing. What is the correct term for software that does star catalog matching?
