I might be wrong, but I don't think they are data captured in real-time. Based on a cursory understanding of the AGI STK, these satellite positions are calculated from ephemeris data which are updated on a regular basis (e.g. weekly). https://en.wikipedia.org/wiki/Ephemeris https://en.wikipedia.org/wiki/Ephemeris

The ephemeris data is updated approximately daily and also allows you to predict the satellite's position fairly accurately several days in the future. Satellites change orbits very infrequently, so it's close enough to real time for most purposes.
