Present VSAT networks use Geostationary satellites, which are satellites orbiting in the equatorial plane of the earth at an altitude above 35786 km away from the earth’s surface. The satellite moves on its circular orbit in the same direction of earth rotation with the equal speed of earth rotation, thus satellite appears from any station on the ground as a fixed relay in the sky.
VSAT SYSTEMS VSAT systems consist of three major components: a hub, the satellite, and the VSATs themselves. These are usually configured as a star topology network. Messages from the VSATs are sent over a channel shared either by time division multiple access (TDMA) or frequency division multiple access (FDMA). These access methods allow each VSAT […]
