GLOBAL TELECOMMUNICATIONS SYSTEM



For as the lightning cometh out of the east, and shineth even unto the west;.."[Matthew 24:27]


It is a Biblical prophechy refer to a teachnology of satellite communication that vital role in the global telecommunication system..like a lightning cometh out of the east , and shineth even unto the west as a fastest system of transmission of signal worldwide 

Under the whole heaven He lets it loose, And His lightning to the ends of the earth.[Job 37:3]
A communications satellite or comsat is an artificial satellite sent to space for the purpose of telecommunications. Modern communications satellites use a variety of orbits including geostationary orbits, Molniya orbits, elliptical orbits and low (polar and non-polar) Earth orbits.

For fixed (point-to-point) services, communications satellites provide a microwave radio relay technology complementary to that of communication cables. They are also used for mobile applications such as communications to ships, vehicles, planes and hand-held terminals, and for TV and radiobroadcasting.

[Romans 10:18]
But I say, Have they not heard? Yes verily, their sound went into all the earth, and their words unto the ends of the world.


satellite communication, in telecommunications, the use of artificial satellites to provide communication links between various points on Earth. Satellite communications play a vital role in the global telecommunications system. Approximately 2,000 artificial satellites orbiting Earth relay analog and digital signals carrying voice, video, and data to and from one or many locations worldwide.



Satellite communication has two main components: the ground segment, which consists of fixed or mobile transmission, reception, and ancillary equipment, and the space segment, which primarily is the satellite itself. A typical satellite link involves the transmission or uplinking of a signal from an Earth station to a satellite. The satellite then receives and amplifies the signal and retransmits it back to Earth, where it is received and reamplified by Earth stations and terminals. Satellite receivers on the ground include direct-to-home (DTH) satellite equipment, mobile reception equipment in aircraft, satellite telephones, and handheld devices.
