针对不同系统观测量测量精度不同的问题,根据多项式拟合原理,在GNSS周跳探测过程中,该文提出了一种根据实测数据设置动态阈值的阈值构造方法,以替代传统方法中采用固定先验值的做法。实验结果显示把该阈值构造方法应用于对小周跳敏感的电离层残差法进行周跳探测时,该动态阈值构造方法可以准确地探测出大小周跳、连续周跳及野值。
For the different view of measurement system with different accuracy problems,according to the principle of polynomial fitting,a method using the measured data seting dynamic threshold adaptive dynamic threshold construction was proposed to replace traditional methods utilizing the priority fixed value approach in GNSS cycle slip detection process in the paper.The results showed that the construction method can accurately detect the size weeks jump,continuous cycle slip and outliers.
