This is awesome. Many years ago I tried making an Android app for uni that would help you point your phone at the star you selected. The maths for that was insa

  It might actually be easier since they have know trajectories and velocities with a easy to calculate schedules.

That makes it quite easy to calculate its current location using orbit propagation algorithms. If you want to go down a fun path I suggest reading more into TLE data. They are currently in the process of adapting the standard to allow for more satellites since in its current form it can only track 99,999 satellites

  There are libraries built with all of this math done for you already. Astropy, orekit are two I recall from memory, but there are more
