Webli network provides VSAT is the use of satellite communication through a VSAT terminal on a 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. The antenna is constantly pointing at the satellite it uses to transmit and receive signals.
Initially the use of VSAT antennas at sea was for transmission of television signals. One of the first companies to manufacture stabilized VSAT antennas was SeaTel of Concord, California which launched their first stabilized antenna in 1978. Sea Tel dominates the supply of two-way VSAT stabilised antenna systems to the marine market with almost 72 percent of the market in 2007 compared with Orbit’s 17.6 per cent. Initially maritime VSAT was using Single Channel Per Carrier - SCPC technology - which suited large volume users like oil drilling rigs and oil platforms and large fleets of ships from one shipowner sailing within one or few satellite footprints. This changed when the company iDirect launched its IP-based Time Division Multiple Access (TDMA) technology that dynamically allocated bandwidth to each ship for shared bandwidth, lowering the entry level cost for getting maritime VSAT installed, which turned out to be of key importance to small-to mid-sized fleets, and thus to the market acceptance of VSAT.
Webli working to VSAT system using 2013, Modern VSAT systems are a prime example of convergence, and hence require skills from both the RF and IP domains. VSAT specific good connectivity on IP network communication.
