先验光压模型对Galileo卫星产品性能的影响分析
|
摘要
光压模型的精确与否对导航卫星的定轨精度起着至关重要的影响.为了分析先验光压模型对Galileo卫星轨道和钟差解算精度的影响,本文利用Galileo/GPS联合数据处理策略对比了先验光压模型加入前后,IOV(In Orbit Validation)卫星和FOC(Full Operational Capability)卫星轨道和钟差解算精度的改善情况.结果显示,先验光压模型对IOV卫星定轨精度改善显著,尤其表现在径向方向,与COM轨道产品比较,定轨精度为1.6 cm,改善率达到68.6%;先验光压模型对FOC卫星定轨精度的改善效果不如IOV卫星,但同样提高了FOC卫星的定轨精度,与COM轨道产品比较,径向定轨精度2.6 cm,改善率为29.7%.此外,先验光压模型也显著改善了IOV卫星和FOC卫星钟差解算的STD结果,与COM钟差产品比较,改善率分别为44%和37%.
The accuracy of the solar radiation pressure model plays a crucial role in the orbit determination accuracy of navigation satellites. In order to analyze the influence of the a priori solar radiation pressure model on the calculation accuracy of orbit and clock bias of Galileo satellite, in this paper, Galileo/GPS combined data processing strategy is used to compare the improvement of the orbit and clock bias calculation accuracy for IOV(In-Orbit Validation) and FOC(Full Operational Capability) satellites pre and post the a priori solar radiation pressure model is added. The results show that the orbit determination accuracy of the IOV satellite is significantly improved by the a priori solar radiation pressure model, especially in the radial direction. Compared with the COM orbital products, the orbit determination accuracy is 1.6 cm, and the improvement rate reaches 68.6%. The improvement effect of the a priori solar radiation pressure model on the orbit determination accuracy of the FOC satellite is not as good as that of the IOV satellite, but it also improves the orbit determination accuracy of the FOC satellite. Compared with the COM orbital products, the radial orbit determination accuracy is 2.6 cm, and the improvement rate is 29.7%. In addition, the a priori solar radiation pressure model also significantly improves the STD results of clock biases for IOV and FOC satellites. Compared with COM clock bias products, the improvement rates are 44% and 37%, respectively.
