Communications satellite of a GEO satellite. Like LEOs, these satellites don’t maintain a stationary distance from the earth. This is in contrast to the geostationary orbit, where satellites are always approximately from the earth. Typically the orbit of a medium earth orbit satellite is about above earth. In various patterns, these satellites make the trip around earth in anywhere from 2 to 8 hours. In 1962, the first communications satellite, Telstar, was launched. It was a medium earth orbit satellite designed to help facilitate high-speed telephone signals. Although it was the first practical way to transmit signals over the horizon, its major
Satellite contribution Satellite contribution A Satellite contribution link or service is a means to transport video programming by a satellite link from a remote source (such as an outside broadcast unit) to a broadcaster's studio or from the studio to a satellite TV uplink centre (for onward distribution by DTH, cable etc.). Such contribution links are often made by terrestrial connections (landline, fibre, etc.) but the use of a satellite "hop" provides advantages in some situations. Satellite operators and third party agencies provide satellite contribution links for the occasional or regular use of the client broadcasters. In remote locations, using terrestrial links
