Gw mau tau Téhnolohi dari VSAT. Jelasin dalam bahasa sunda

Initially the use of VSAT antennas at séa 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. Séa 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 éach 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.
