| Abstract: | The formulas to predict the interference of the sun and moon with the infrared earth sensor of geostationary orbit satellite and the prediction method were derived based on the positions of the sun and moon and orbit elements of the satellite in engineering in this paper.The computation model was presented of the angle change for the antenna when the Z axis of the on-orbit satellite tracing the sun to ensure the power supply in safety model.The calculation results and telemetry data downloaded from the satellite showed that this method was correct,which would be applied in satellite's operation management. |
