What is VSAT and how it works?

What is VSAT and how it works?

A very small aperture terminal (VSAT) is a small-sized earth station used in the transmit/receive of data, voice and video signals over a satellite communication network, excluding broadcast television.

How do you use VSAT?

A VSAT user requires a box to read between the user’s computer and an outdoor antenna which has a transceiver. The transceiver is used to send and receive signal to and from a satellite transponder via an earth based station known as ‘hub’ which is interconnected with the satellite.

What is VSAT in aviation?

ATNS, in partnership with Africa’s developing countries, endeavours to enhance safety and contribute to developing global aviation intelligence by keeping seamless aeronautical communication from Cape to Cairo. Today, ATNS is making this a reality through our very small aperture terminal (VSAT) network link.

What is VSAT installation?

Very Small Aperture Terminal (VSAT) refers to a earth station linked to satellite using RF link and usually will have different diameter antennas. VSATs provide the important communication link to set up a satellite based communication network. VSATs can be used for voice, data, or video transmission and reception.

What satellite does VSAT use?

VSATs access satellites in geosynchronous orbit or geostationary orbit to relay data from small remote Earth stations (terminals) to other terminals (in mesh topology) or master Earth station “hubs” (in star topology).

What is VSAT equipment?

A very-small-aperture terminal (VSAT) is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s up to 16 Mbit/s.

What are the advantages of VSAT?

➨VSAT provides same quality of service and speed at all the locations across the entire VSAT network. ➨VSAT services are independant of other wired and wireless mediums used as transmission network service provider. Hence it is a great backup system which is available during disaster and emergency situations.
