This image of the satelitte orbits makes the comparison easier: https://en.wikipedia.org/wiki/Geostationary_orbit#/media/Fil... The geosync satellites are very high, 5.6 Earth radius above the Earth surface. (The radius of the orbit is 6.6 Earth radius.) And you have to multiply it by 2 because the signal has to go from the ISS to the satellite and then to Earth. The ISS is only 0.06 Earth radius above the Earth surface approximately. So in this case, most of the latency will come from horizontal travel (and the latency of the usual congestion in the net). |
