摘要
"北斗"卫星导航定位系统可以进行高精度单点定位和相对定位。本文针对该系统提出了一种相对定位选星策略,分析了几种双频组合方法及适用范围,给出了一种利用B1和B3频率进行双频载波相位差分的方法,并针对具体应用进行了仿真器环境试验验证,为"北斗"卫星导航定位系统建成后高精度相对定位应用提供参考。
High-accuracy single point positioning and relative positioning is made possible by Beidou Satellite Navigation System.This paper presents a satellite-selection strategy for relative positioning.A few dual-frequency combinations and their scope of applications are analyzed and a method is given for relative positioning using B1 and B3 frequencies.The method is verified with a Beidou signal simulator for applications in reality,providing technical reference for high-accuracy relative positioning when the entire Beidou satellite navigation system constellation is established.
