摘要/Abstract

摘要： 随着无人驾驶等高新技术的快速发展，实时精密单点定位在GNSS领域中受到越来越多的关注。研究实时卫星钟差的获取和实时定位精度具有较大的现实意义，本文为研究耦合BDS卫星轨道、钟差产品对定位精度的影响，采用不同精度的轨道产品实时获取卫星钟差。分析了卫星钟差误差与轨道误差之间的相关性及钟差对轨道误差的吸收能力，发现卫星钟差能够吸收95%以上的轨道径向误差和部分切线误差，在一定程度上弥补了轨道误差引起的定位误差。采用耦合的卫星轨道、钟差产品，单BDS系统定位精度可达到分米级的定位结果。

Abstract: With the rapid development of high-tech such as unmanned driving, real-time precise single point positioning has attracted more and more attention in the field of GNSS. It is of great practical significance to study the acquisition of real-time satellite clock error and the accuracy of real-time positioning. In order to study the influence of coupling BDS satellite orbit and clock error products on positioning accuracy, different precision orbit products are used to acquire satellite clock error in real-time. It studies the correlation between satellite clock offset and orbit error as well as the ability of satellite clock offset to absorb orbit error. The results show that the satellite clock offset can absorb 95% of the orbital error in radial and partial tangential error, and some extent compensate for the positioning error caused by the orbital error. Using coupled satellite orbit and clock difference products, the positioning accuracy of a single BDS system can reach decimeter-level positioning results.

Key words: BDS, real-time clock offset, orbit error, SISURE, PPP
