| 摘 要： | 以GRACE卫星为例,分析比较利用SLR观测资料进行卫星定轨时,采用不同重力场模型对GRACE卫星定轨精度的影响;以及重力场截断阶引起的积分轨道差异;同时,将定轨结果与采用GPS确定的定轨结果进行比较,分析与GPS定轨结果的差异.实验证明.重力场模型选择GGM02C的定轨结果优于选择JGM-3的定轨结果,基于SLR的定...

| Abstract: | The paper takes GRACE satellite as an example.Then,it analyzes the different effects on orbit determination caused by different models based on SLR observation of GRACE satellite,and the truncation order of the gravity field caused by differences in the integral rail.Finally,the paper compares the orbit determination result of SLR with GPS.Experimental results show that the gravity field model selection GGM02C orbit determination results were better than JGM-3 orbit determination results.SLR-based orbit det... |
