	VSAT - Very Small Aperture Terminal \|\| atrexx
		VSAT describes a small terminal that can be used for one-way and/or interactive communications via satellite.
		From banks to administrations, schools, hospitals, and rural telecommunications, VSATs are being seized upon to elevate economic, educational, and health standards.
		VSATs have been in use for more than 10 years and, with more than 500,000 systems operating in more than 120 countries, VSATs are a mature and proven technology.

	Very small aperture terminal - Wikipedia, the free encyclopedia
		VSAT is also used by local car dealerships affiliated with manufacturers such as Ford and General Motors, for transmitting and receiving sales figures and orders, as well as for receiving internal communications, parts ordering, service bulletins, and interactive distance learning training courses from the manufacturer.
		VSAT technology is also used for 2-way satellite internet providers such as DirecWay and StarBand in the US, and Amariska, Bluestream and Technologie Satelitarne in Europe, among others.
		Some VSAT networks are configured by having several centralized uplink sites (and VSAT terminals stemming from it) connected in a multi-star topology with each star (and each terminal in each star) connected to each other in a mesh topology.

	VSAT Technology - Telesindo Mulia
		VSAT technology is a telecommunication system based on wireless satellite technology.
		As the definition itself indicates, VSAT technology is made up of a small satellite earth station and a typical antenna of 1.8 meter diameter.
		The VSAT outdoor unit consists of a standard 1.8 meter offset feed antenna, a solid state amplifier (SSPA), a Low Noise Amplifier (LNA), and a Feedhorn.

	ESA - USO - VSAT Licensing Tutorial
		A satellite terminal is the complete combination of equipment parts that compose the end-user communication system: it consists in general of an outdoor part (the antenna) and an indoor part (the user interface, display, console).
		VSAT is an acronym for Very Small Aperture Terminal.
		VSATs are small, cheap, and easy to install and are used for all kinds of telecommunications applications such as: corporate networks (for example connecting fuel station pay systems), rural telecoms, distance learning, telemedicine, transportable satellite news gathering uplinks etc.

		VSAT networks are networks of technically identical small antennas that generally communicate with a larger hub station.
		We stated that the VSAT industry has matured to a point where it is no longer necessary to monitor system build-out on a yearly basis.
		While a widescale revision of VSAT antenna standards is beyond the scope of this rulemaking, we agree that in light of the rapid development of VSAT technology, a comprehensive review is needed.

		In order to distinguish VSATs from other satellite earth stations and receivers, the original VSAT definition was based on the antenna’s size, which had to have a parabolic reflector of between one and 2.4 metres.
		Digital compression is an enabling technology that allows terminals to be very small, whilst supporting wideband services that can deliver, for example, 200 channels of TV or wideband data.
		Terminal antenna diameters can now be as small as 0.55 metre, which is well below the old VSAT definition and very close to the purely arbitrary 0.50 metre definition of a USAT.

		VSAT licensees have steadily constructed their networks during the four year implementation period but generally require more than four years to complete construction of their entire network.
		In light of the maturity of the VSAT service and because VSAT licensees have been aggressive in constructing their networks, continuing the four year implementation period is unnecessary.
		We also propose to remove Section 25.115(c)(1) and (c)(5) of our rules, which require applicants seeking authority to construct and operate VSAT networks to include a general narrative section describing the proposed applicant and system and to designate a point of contact where records of location and frequency use are maintained.

	Satellite Communications VSAT Very Small Aperture Terminal Installation
		The use of VSAT systems is growing throughout the world as a way of establishing private satellite communications networks for large organisations that have several widely dispersed locations, or providing higher bandwidth for the individual.
		By linking VSAT terminals to larger hub stations (or land earth stations), a network can be established inexpensively, although in this type of configuration, VSATs can communicate only via the hub and not from remote terminal to remote terminal.
		VSAT networks can readily be configured so that the hub can broadcast data to all the VSAT terminals at higher rates than they can communicate to the hub.
