讨论了移动基准站GPS载波相位差分技术的关键,研究了其确定整周模糊度的方法,设计了检验该技术精度的试验方案,实现了厘米级的相对定位精度。
An ambiguity algorithm for GPS precise relative positioning in moving base station is discussed in detail. Five GPS receivers are used to construct a test system. The demonstrating results indicate that cm-level accuracy is achieved for DGPS kinematical positioning.
