摘要
A system and method for controlling uplink power to combat rain fade in satellite communication systems. First communication signals transmitted from a satellite to a satellite operations center are monitored at a gateway. A downlink attenuation level is determined for the first communication signals, and compared to an ideal attenuation level. if the downlink attenuation level exceeds the ideal attenuation level, then a corresponding uplink attenuation level is determined for a second frequency used to transmit second communication signals to the satellite, and converted to a power control command for adjusting an amplifier gain. The second communication signals are transmitted to the satellite at either a compensated power level or a normal power level, depending on whether the downlink attenuation level exceeds the ideal attenuation level.
