Several GVN's are currently operated by the U.S. Government

To meet the global demand for rapidly installed telephony and data communications Satellite Networks has developed the Ground VSAT Network (GVN) for commercial and government Commercial Off The Shelf (COTS) applications.

GVN is a commercial satellite communications closed network approved for operation over INTELSAT or PanAmSat in the Ku-band frequency range. The network is designed to balance space segment power and bandwidth for the lowest operating cost. The network is transportable and deployed in a star configuration consisting of a hub station at the center with up to 24 remote (spoke) terminals. Each spoke terminal can provide 2 voice, 1 fax and 2 data connections to the hub terminal. The hub station can also communicate with other hubs. A hub station host computer exercises local monitor and control (M&C) of hub station electronics as well as a dedicated channel for over-the-satellite M&C of the network spoke terminals.

GVN hub stations employ 2.4-meter antennas with redundant RF subsystems (LNA, HPA and transceiver). Spoke stations typically utilize 1.8-meter antennas with single thread electronics. Hub stations meet INTELSAT E1 standards; spoke stations are qualifiable as INTELSAT standard G terminals.

Hub and spoke electronic are either antenna mounted or enclosed integrated and ruggedized transit cases. Provision is made for data encryption using either Satellite Networks or customer provided data encryption equipment.

A network PBX provides more channel connectivity, spoke to hub or spoke to spoke.
