Methods and apparatus for controlling earth-station transmitted power in a VSAT network

摘要

A method is shown for providing stable communication between a hub earth-station and a VSAT earth-station by regulating the power of signals transmitted via a satellite. In this method, the hub receives a beacon signal from the satellite and a previous outbound signal. The hub then regulates the power of an outbound signal transmitted by the hub to VSAT via the satellite, based on either the beacon signal or the previous outbound signal. The hub then sends a current outbound signal, including signal data and parameter data to the VSAT via the satellite. The VSAT receives the current outbound signal and determines a number of signal properties pertaining to the current outbound signal. The VSAT then regulates the power of an inbound signal transmitted by the VSAT to the hub via the satellite, based on the signal properties, the parameter data, and a set of reference data.
