Abstract:
A method of adjusting an uplink signal power of a terminal in a satellite communications system, the method comprising the steps of:transmitting an uplink signal from an originating terminal to a satellite, the uplink signal being transmitted with a first transmitted uplink signal power, the uplink signal having a data packet containing information identifying the originating terminal; receiving the uplink signal at the satellite, the uplink signal received with a received uplink signal power; demodulating the received uplink signal and measuring the received uplink signal power at the satellite; creating a downlink data packet for transmission to the originating terminal, the downlink data packet containing the identification information from the uplink data packet and the information of the received uplink signal power; transmitting information of the received uplink signal power from the satellite to the originating terminal in a downlink signal, the downlink signal having a data packet containing information identifying the originating terminal; receiving the downlink signal at the originating terminal; and transmitting subsequent uplink signals with a second transmitted uplink signal power, the second transmitted uplink signal power being determined based on the transmitted information of the received uplink signal power.
