基于广西BDS观测数据的PPP算法研究与精度分析
Research on BDS PPP Algorithm and Precision Analysis by Using BDS Data in Guangxi
摘要
Abstract
At present,Beidou navigation satellite system (BDS) has been officially running,which leads to the application of BDS in other industries.In this paper,BDS PPP algorithm based on ionosphere-free combination is achieved with BDS observational data of Guangxi.With the iGMAS orbit and clock products,the positioning accuracy of BDS is analyzed by using of three situations (0.5 hours,2 hours and 24 hours) in Guangxi.The results show that the 2 hours of BDS observation data can be used in PPP calculation,which can fully meet the requirements of the measurement accuracy of 1:2 000 scale aerial camera control points in China.The results can provide technical support for Beidou satellite navigation system in China's low latitude areas,as well as the promotion and application of ASEAN countries.关键词
