摘要
GPS双移动载波相位差分技术的关键,是如何实现可变基线条件下整周模糊度的快速解算。为此,本文详细地讨论了其确定整周模糊度的方法,并设计了检验该技术精度的实验方案;实算结果表明,用该技术获得了厘米级的相对定位精度。
The key problem of DGPS carrier phase measurements for two moving bodies is how to get a fast ambiguity solution under varying baselines.This paper discusses an ambiguity algorithm for GPS precise relative positioning in two moving bodies in detail and demonstrates its efficiency by means of five GPS receivers used to construct a test system.The demonstrating results indicate that cm-level accuracy was achieved for DGPS kinematical positioning.
