What is the meaning of aperture Terminal?

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.

What is a satellite terminal definition?

A satellite terminal is a building detached from other airport buildings, so that aircraft can park around its entire circumference. The first airport to use a satellite terminal was London Gatwick Airport. It used an underground pedestrian tunnel to connect the satellite to the main terminal.

Where is VSAT used?

A very small aperture terminal (VSAT) is a data transmission technology used for many types of data management and in high-frequency trading. VSAT can be used in place of a large physical network as it bounces the signal from satellites instead of being transported through physical means like an ethernet connection.

What is a VSAT dish?

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.

How VSAT is used in education?

VSAT system provides a stable transmission via satellite. However, only oneway transmission is possible through VSAT. Learners can only listen to the lecture delivered via radio or TV. Real learning happens when both educator and learners can communicate freely and instantly without any restrictions.

How does a VSAT work?

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 pier finger terminal?

Pier finger terminal is known as decentralized facilities, with some of the required processing performed in common-use main terminal areas, and other processes performed in and around individual concourses.

What is Satellite terminal railway station?

NEW DELHI: To reduce congestion at its main railway station, Indian Railways is now planning to develop ‘satellite’ railway stations which will not only save the time of passengers in reaching the railway station but would also reduce congestion on the roads and reduce pollution as well.

What is Ku frequency band?

12–18 GHz
Ku-band (12–18 GHz) Used for satellite communications. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra.

What is VSAT WIFI?

VSAT is a technology used to define two-way-satellite communications. VSAT systems use small dish antennas that vary from 75 cm to 2.4 meters in diameter. VSAT terminals access satellites in orbit, to transfer data from one earth station to another or to access the Internet (two-way satellite Internet).
