What orbit do the Inmarsat GEO satellites operate in?

Inmarsat GEO satellites operate in a geostationary orbit, which is approximately 22,236 miles (about 35,786 kilometers) above the Earth’s equator. This altitude allows satellites in this orbit to maintain a fixed position relative to the surface of the Earth, effectively making them appear stationary to ground-based antennas. This is particularly beneficial for communication systems, as it simplifies the design and operation of ground equipment, allowing for constant connectivity without the need to track moving satellites. The 22,000 mile distance is a standard for geostationary satellites, making this option the correct choice for the question regarding the orbit of Inmarsat GEO satellites.

The alternative distances presented in the other options do not correspond to any recognized standard or specific operational orbit for geostationary satellites.
