Abstract
The disclosure describes a method of adjusting a reference level for uplink signal power for use in a dynamic power control system with satellite-based measurements in a satellite communications system. The uplink signal power for a plurality of received uplink signals is measured and combined to determine whether a signal power reference level requires adjustment. The signal powers of a plurality of uplink signals are measured at the satellite and the received signals are validated to ensure the signals are acceptable for use in adjusting the reference level. The valid signals are used to calculate an average signal power of the measured uplink signal powers, with the calculated average being compared to the current value of the reference level. Based on the comparison, the reference level either retains the current value or is reset to an adjusted value.
