摘要
本文基于高低卫卫跟踪的模式，用积分方法研究了不同重力场模型对于轨道的影响，并用3个月的GRACE轨道数据计算了新的60阶地球重力场模型，为了分析其精度，与EGM96和EIGENIS作了比较．结果表明新模型在40阶前更接近GGM02C模型。
In this paper, the effect of the earth gravity model on satellite orbit are analyzed by applying the method of integral method,hased on the high low satellite to satellite tracking mode. A new earth gravity model up to degree 60 is recovered using 3 months GRACE data. The accuracy of the new model is compared with one of the EGM96 model and EIGENIS model. It shows that the new model is closer to GGM02C model before degree 40 than the two others.
