摘要
对传统的周跳探测理论和方法进行了改进,实现了非差载波相位周跳的实时探测。通过对Geome-try-free组合和Melbourne-Wbbena组合的特性进行分析,同时利用滤波技术,很好地实现了周跳的实时探测。对GPS车载动态数据以及星载GPS数据进行了仿实时模拟,实验结果表明,本文方法能实时地探测出1周的GPS非差载波相位周跳。
Based on the conventional theories of cycle-slip detection, a method is developed to detect cycle slips in real time for quality control. The method utilizes two linear combinations, the Geometry-free and Melbourne-Wtibbena combinations. The characteristics of the two combinations are analyzed and the filer techniques are used to deal with the time series of combination observations. Real-time simulation tests are implemented using both vehicle kinematic data and on-board kinematic data. The results show that single-cycle slips can be reliably detected in real time.
