A terrestrial system for satellite communication is one that facilitates. This includes the facilitation of audio, data, and any other communication.

Why Fresnel zone affecting satellite and ground communication?
For communication satellites the range is much higher than that of communication relay. Communication Satellite can cover up to several thousands of kilometers. For communication relay, the uplink and the downlink frequency is the same. But for communication satellites the uplink and the downlink frequencies are different in order to avoid interference.
Answer: 1.communication satellite 2.navigational satellite 3.weather satellite 4.millitary satellite 5.scientific satellite 6.satellite launches. It composed of 6 satellites...........i hope.....my answer can help you.....
Aryabhatt satelite was use in communication
Satellite communication is one particular example of wireless communication systems. Similar and maybe more familiar examples of wireless systems are radio and television broadcasting and mobile and cordless telephones. Systems of this type rely on a network of ground-based transmitters and receivers. They are commonly referred to as 'terrestrial' systems as opposed to satellite systems. these are the following important element in the satellite communication system 1.user 2.terrestrial system 3.earth station 4.repeaters user: user are located on the earth and they produces the baseband signal terrestrial system: terrestrial system can be switch or telephone line or network. the function of terrestrial system is to proceed the baseband signal to the earth station which are coming from the user earth station : Earth station is the common name for every installation located on the Earth's surface and intended for communication (transmission and/or reception) with one or more satellites. Earth stations include all devices and installations for satellite communications: handheld devices for mobile satellite telephony, briefcase satellite phones, satellite TV reception, as well as installations that are less familiar, eg VSAT stations and satellite broadcast TV stations. The term Earth station refers to the collection of equipment that is needed to perform communications via satellite: the antenna (often a dish) and the associated equipment (receiver/decoder, transmitter). repeaters: repeaters accept all the modulated R.F career in its uplink and amplifies back it to earth station in its down link

definition of optical satellite communication
The first communication satellite was Echo NASA
Satellite-based cellular systems In addition to the terrestrial systems, in recent years satellite-based telephone systems have been under construction. With such a system it is possible to make a connection with a cellular phone all around the world, especially in those regions currently not covered by a terrestrial system. In contrast with other satellite communication systems, satellite-based phone systems operate in the Low Earth Orbit (780 km high), and are therefore called LEO systems. The satellites work differently from those at a much higher orbit (36,000 km) in two major ways. First, the small distance between earth and satellite makes it possible to connect to the system with a handheld device. Second, signals can be moved overhead in between satellites without the use of base stations on the earth. In the near future, operators will supply services in which terrestrial and satellite communication are integrated. Like in the terrestrial systems, the satellites operate on certain frequencies, that have to be selected in such a way that interference is avoided. Not only frequencies are needed to communicate with handheld devices, but also to establish communication between satellites and ground stations, and between satellites mutually. cellular telecommunication networks One of the most recent applications of wireless communication is the establishment of fixed cellular telecommunication networks. In contrast to mobile cellular networks, in non-mobile or fixed systems both the transmitters and receivers are located at fixed points in the area. Fixed cellular networks provide a financially attractive alternative to the construction of conventional wired networks in developing countries, where no
Satellites lack the geographic constraints of terrestrial systems
IN COMMUNICATIONS: Satellite uses satellite (orbiting) relay-stations in Space but Terrestrial uses cable or antenna-to-antenna signals based entirely on Earth to broadcast your television, radio or cell-phone :) ++++ IN ASTRONOMY: Terrestrial means Earth- (or planet-) bound; a Satellite is any natural or man-made object that orbits a planet. The Moon is a satellite of the Earth.
Terrestrial noise is noise that originates on the earth. Extra terrestrial noise comes from space.
