giantg2 is right! The position and velocities are already known in the form of a Two-line element set (TLE). 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
