He is also credited with popularizing the idea of the geostationary satellite. Now, hundreds of geostationary satellites provide continuous communications to all the peoples of the world.

Satellites that provide television coverage, for instance, are a type of geostationary satellite.

A geostationary orbit is a specific type of geosynchronous orbit (where a satellite in orbit is positioned above the same spot on Earth all of the time), one that is in a circular orbit and directly above the Earth’s equator.

The orbit, approximately 22,236 miles (35,786 kilometers) above the surface of the Earth, is commonly called a Clarke orbit in honor of Arthur C. Clarke.
