13 Facts About Communication satellite

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.

The Communication satellite was not placed in orbit for the purpose of sending data from one point on earth to another; the radio transmitter was meant to study the properties of radio wave distribution throughout the ionosphere.

Since the Communication satellite is so far above Earth, the radio signal is attenuated due to free-space path loss, so the signal received on Earth is very, very weak.

The Communication satellite executed several realtime transmissions before the non-rechargeable batteries failed on 30 December 1958 after eight hours of actual operation.

Echo 1 was an aluminized balloon Communication satellite acting as a passive reflector of microwave signals.

Molniya orbit is designed so that the Communication satellite spends the great majority of its time over the far northern latitudes, during which its ground footprint moves only slightly.

Bandwidth available from a Communication satellite depends upon the number of transponders provided by the Communication satellite.
