Syncom 2 was the first communications satellite in a geosynchronous orbit. It revolved around the Earth once per day at constant speed, but because it still had north–south motion, special equipment was needed to track it. [19] Its successor, Syncom 3, launched on 19 July 1964, was the first geostationary communications satellite. Syncom 3 ...
Syncom 3 was the first geostationary communication satellite, launched on August 19, 1964 with the Delta D #25 launch vehicle from Cape Canaveral. The satellite, in orbit near the International Date Line , had the addition of a wideband channel for television and was used to telecast the 1964 Summer Olympics in Tokyo to the United States .

Satellite communications are affected by moisture and various forms of precipitation (such as rain or snow) in the signal path between end users or ground stations and the satellite being utilized. This interference with the signal is known as rain fade. The effects are less pronounced on the lower frequency 'L' and 'C' bands but can become ...
An antenna tracking system tracks a primary antenna to follow a moving signal source, such as a communication satellite.A secondary antenna has a greater beam width than the primary antenna and receives the same tracking signal from the satellite.
The message recorded of Eisenhower.. SCORE (Signal Communications by Orbiting Relay Equipment) was the world's first purpose-built communications satellite.Launched aboard an American Atlas rocket on December 18, 1958, SCORE provided the second test of a communications relay system in space (the first having been provided by the USAF/NASA's Pioneer 1), [3] the first broadcast of a human voice ...
