1. A method of adjusting a reference level for use in a dynamic power control system with satellite-based measurements in a satellite communications system, the method comprising the steps of:

  • measuring an uplink signal power of a plurality of uplink signals received at a satellite, the uplink signals transmitted by a plurality of terminals;

    determining whether each received uplink signal is a valid signal for use in adjusting the reference level, said reference level being a function of the uplink power received at the satellite;

    comparing the measured uplink signal powers of the valid signals to a current value of the reference level; and

    adjusting the reference level to an adjusted value based on result of the comparison step.
