VSAT is commonly used for telemetry or SCADA applications in remote unmanned locations. The reliability and stability of the satellite communication link is imperative. When the VSAT link is down, the solution that is described here will be activated to re-establish the link via the BGAN network. This backup system is able to perform diagnostic function for the VSAT.
The two main equipment used in the VSAT backup solution over BGAN are a Remotely Controllable SABRETM 1 (SABRETM 1 Remote) and an embedded PC device (IOTATM).
