Communication Satellite, launch and used by Philiipines
introduction of satellite based communication
satellite is satellite
definition of optical satellite communication
The first communication satellite was Echo NASA
Microwaves. These poke through the ionosphere to reach the satellite
A satellite.
Light weighted antennas are used for communication
In satellite communication uplink (transmission of signal from earth station to satellite ) & downlink (reception of signal from satellite to earth station) takes place TX & RX involves a finite amount of delay which is acceptable in data communication, but i audio & video TX this delay is unacceptable, overlapping/ alaising causes errors which demodulated by qpsk.
Why Fresnel zone affecting satellite and ground communication?
Com = Communication, Sat = Satellite
