A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [1] 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 to 16 Mbit/s.
How satellite internet works. Satellite Internet generally relies on three primary components: a satellite – historically in geostationary orbit (or GEO) but now increasingly in Low Earth orbit (LEO) or Medium Earth orbit MEO) [23] – a number of ground stations known as gateways that relay Internet data to and from the satellite via radio waves (), and further ground stations to serve each ...
Maritime VSAT is the use of satellite communication through a Very-small-aperture terminal (VSAT) on a moving ship at sea. Since a ship at sea moves with the water, the antenna needs to be stabilized with reference to the horizon and True north, so that the antenna is constantly pointing at the satellite it uses to transmit and receive signals.
The Santander teleport is a joint venture developed and completed by MTN and its technology partner, Erzia, a provider of VSAT maritime communications in Spain. [1] The Santander teleport serves as a centralized gateway for MTN's VSAT communications with coverage over the Americas, Europe, and Asia.
