Satellite telecommunications system parts
Telecommunication Satellite System may be a series of house stations and ground stations to broadcast Ayjadartbatat . Portion of this satellite system is fashioned solely on one satellite and also the ground stations . This sets a ( satellite network ) is termed .
Space Station satellite channel communications satellites ( Main Network ) has been fashioned and peripherals .
Vghyrmkhabraty satellite communications instrumentation consists of 2 elements . Communication subsystems , antennas and repeater square measure. within the telecommunication sector , there's a tool that performs radio relay repeater operate and ( Transpandr ) is termed . Transpandrha signals sent from the sphere once receiving Aztqvyt Vtghyyrfrkans them to the sender.
The antennas square measure designed to Transpandrha that solely elements of the bottom level square measure Khdrvn satellite network covers . typically a satellite antenna for receiving command signals issued from the bottom all the thanks to the opposite satellite antenna is employed as a result of it's unlikely to land .
All transmitting aerial sub- system conjointly took management of the satellite and its position is employed . Sector within the technical support is enclosed Ghyrmkhabraty satellite thermal system , the position of the system chip Building mechanical offer system is engine peak .

Satellite Thermal system
The temperature within the satellite system ought to be moderately and traditional devices and instrumentation to take care of.
Position system chip
It controls the position of the satellite antenna to the specified exit direction of frequence force field holds steady .
The mechanical structure
