摘要	When using the forecasting data of satellite orbit to guide the optoelectronic tracking device, the guiding data of satellite need to be solved according to the orbital element of the satellite and the coordinates of the optoelectronic device. The widely used satellite orbit forecasting model is based on the SGP4/SDP4 model (simple and convention/approximate analysis model of deep space perturbation) based on TLE format. This model has relatively high calculation speed, but the solving precision can not satisfy the guiding requirement of the optoelectronic device. Therefore, the orbit needs to be corrected with the mechanical model of the satellite orbit perturbation when solving the guiding data of the satellite. In this paper, the perturbation mechanical model of the satellite orbit is corrected using the main parameters such, as the earth gravitational field, the attractive force between the sun and the moon, the upper atmospheric drag and the solar radiation pressure. After the perturbation correction, the orbit forecasting precision is improved from the azimuth 20' and the pitching 10' to 2' and 1', respectively, which is almost one order of magnitude improvement.
