北斗卫星导航系统伪距差分定位技术的分析

An Analysis of Pseudo-range Differential Positioning Technology of Bei Dou Satellite Navigation System

文章介绍了北斗卫星导航系统(BDS)的伪距差分定位模型。结合GPS的伪距差分定位模型对该模型进行了比较,并对北斗导航系统的整体情况进行了介绍和概述,对比计算基线结果的精度,结果表明北斗导航系统的伪距差分可以达到亚米级的精度,对BDS地基的加固施工提供了新方向;同时还讨论了BDS卫星可见数对伪距差分定位的影响,对以后的工作提供指导借鉴。

This paper introduces the pseudo-range differential positioning model of BeiDou satellite navigation system（BDS）.Based on the pseudo-range differential positioning model of GPS, the model is compared, the overall situation of Bei Dou navigation system is introduced and summarized, and the accuracy of baseline results is compared. The results show that the pseudo-range difference of the Bei Dou navigation system can reach the accuracy of sub-meter level, which provides a new direction for the construction of BDS foundation reinforcement, and the influence of the visible number of BDS satellites on the pseudo-range differential positioning is also discussed.
