摘要
提出综合利用高次差法和多项式拟合法对COMPASS-MEO卫星进行周跳探测的原理及实现方法,并采用COMPASS监测站实测数据使用不同的数据预处理策略对COMPASS-MEO卫星进行精密定轨试验。结果表明,根据实测数据情况,合理选择周跳探测方法和预处理策略,可以改善定轨精度。
How to detect the cycle slip is always the key to data preprocessing for satellite orbit determination.The method of LC-PC combination,Multi-difference combined Polynomial fitting for cycle slip detecting is analyzed,and then the test of orbit precision determination using COMPASS observations is made.It shows that,as for the observations of COMPASS receiver,the accuracy of orbit determination will be improved by choosing the methods of cycle slip detecting and data preprocessing rationally.
