Analyze on GEO Satellites Output Power Variation

摘要

Solar arrays are the main source of energy used at present onboard satellites. Their energy resources largely determines the time of active life of on-orbit satellites. This paper sets up the output power variation model of solar arrays from the telemetry of three-axis stabilized GEO satellites made by China, and based on the model illustrates the influence of output power on on-orbit GEO satellites.
