Detailed explanation-1: -The SCORE (Signal Communication by Orbiting RElay) satellite of US ARMY was a 24.3 metres (80 ft) long, and 3.1 metres (10 ft) diameter Atlas missile used as a platform for the communications relay experiment. The spacecraft body served as antennae.
Detailed explanation-2: -Telecommunications satellites are usually placed in geostationary Earth orbit (GEO). GEO is a circular orbit 35 786 kilometres above Earth’s equator and follows the direction of Earth’s rotation.
Detailed explanation-3: -There are three types of communication services that satellites provide: telecommunications, broadcasting, and data communications.
Detailed explanation-4: -Satellites communicate by using radio waves to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
Detailed explanation-5: -The high frequency radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated geographical points.
