Output Power Variation Analysis on Solar Arrays of Three-axis Stabilized GEO Satellites

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 Academy of Space Technology (CAST), and based on the model illustrates the influence of output power on on-orbit GEO satellites.
