This is a list of satellites in geosynchronous orbit (GSO). These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do.
t. e. A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...
T4S (formerly DirecTV-4S) was successfully launched on November 27, 2001 aboard a Ariane 44LP rocket from the Guiana Space Center on the northeastern coast of South America. T4S was a 9,400-pound, 86-foot-long, and 24.5-foot-wide high powered satellite. T4S was the first satellite for DirecTV to employs spot beams.
For example, satellite television signals are transmitted from the satellite on two separate channels at the same frequency using right and left circular polarization. In a home satellite dish, these are received by two small monopole antennas in the feed horn, oriented at right angles. Each antenna is connected to a separate receiver.
