| 摘 要： | 民用GPS双频接收机主要采用互相关技术和Z跟踪技术消除或减弱A-S(Anti-Spoofing)的影响,获取P(Y)码伪距观测值。文中对两种技术获取的P(Y)码伪距的精度进行了理论分析和实测数据的验证。民用GPS双频接收机获取P(Y)码伪距的意义在于消除或减弱电离层延迟误差的影响,进而提高定位的精度,文中结合单点定位给出了例证。

| Abstract: | In general,civilian GPS receivers adopt cross-correlation and ZTracking technique to eliminate the effect of A-S,and acquire P(Y) code pseudoranges.This paper makes theoretical analysis for the precision of civilian P(Y) code pseudoranges,and then verifies it with experimental data.Especially,P(Y) code pseudoranges of civilian GPS receivers allow eliminating or reducing the ionospheric effect and improve the precision of positioning.The point positioning experiments for this are made in the end. |
