摘　　要：为了研究轨道预报期间光压模型的影响,该文采用2017年8月1日至2017年11月30日的事后精密轨道产品,研究ECOM 5参数模型、ECOM 9参数模型和可校正Box-wing模型对BDS-IGSO/MEO卫星和Galileo卫星轨道预报的影响。预报轨道通过与事后精密轨道对比以及激光检核得到的残差来评价其精度。对于BDS-IGSO/MEO卫星,ECOM 5参数模型和ECOM 9参数模型结果基本一致,可校正Box-wing模型最差,但是在卫星径向精度上,ECOM 9参数模型要优于ECOM 5参数模型。对于Galileo卫星,ECOM 9参数模型要整体优于ECOM 5参数模型。In order to study the effects of the solar radiation pressure model on orbit prediction,the final precise orbit products from August 1,2017 to November 30,2017 were adopted,and the effects of different solar radiation pressure on orbit prediction of BeiDou IGSO,MEO satellite and Galileo satellite were studied in this paper.The solar radiation pressure model includes ECOM 5 parameters model,ECOM 9 parameters model and the adjustable Box-wing model.The predicted orbits were compared with final precise orbits and satellite laser ranging(SLR)observations,and the residuals were used to evaluate the accuracy of predicted orbits.For BeiDou satellite,the results of ECOM 5 parameter model and ECOM9 parameter model were similar.The adjustable Box-wing model was the worst,but in the radial direction of satellite,the ECOM 9 parameter model was superior to the ECOM 5 parameter model.For the Galileo satellite,the ECOM 9 parameter model was better than the ECOM 5 parameter model as a whole.
