摘要
载波相位观测值中的周跳进行探测和修复一直是GPS精密定位数据处理中的一个十分重要的问题。主要讨论基于双频探测的电离层残差法,编制了相应程序,并通过实例分析了在不同采样率条件下探测与修复周跳效果,针对其探测盲区提出了解决方案。
The cycle slip detection is one of the core questions in the GPS data processing.This paper introduced one method of cycle-slip detection—ionosphere residual error method,which required double frequency observations.The computation procedure for ionosphere residual error method was developed,results of processing real GPS data in different time ratio had been discussed,and some solutions to the blind zone of that method were given.
