多项式模型在导航卫星钟差预报中的应用研究
Application of Polynomial Model in Satellite Clock Error Prediction
摘要
Abstract
In order to improve satellite clock error prediction precision,an optimum method based on polynomial model is proposed in this paper.By adjusting the amount of satellite clock data and the rank of polynomial model,different length predicting precision of satellite clock error are improved.To validate the feasibility and effectiveness of this method,this paper analyzes the predicting precision of satellite clock error through the statistics of COMPASS satellite clock error.The analysis shows the satellite clock error prediction precision can be improved,when the amount of satellite clock data and the rank of polynomial model are all optimized.关键词
