Comparison of GPS, GLONASS, Galileo and Compass (medium earth orbit satellites) satellite navigation system orbits with the International Space Station orbit, the Hubble Space Telescope orbit, Geostationary Earth Orbit and the nominal size of the Earth. The Moon's orbit is 9.1 times larger (in radius and length) than geostationary orbit.[1]
  1. Orbital periods and speeds are calculated using the relations 4π²R³ = T²GM and V²R = GM, where R = radius of orbit in metres, T = orbital period in seconds, V = orbital speed in m/s, G = gravitational constant ≈ 6.673×1011 Nm²/kg², M = mass of Earth ≈ 5.98×1024 kg.
