超宽巷组合辅助电离层残差法北斗周跳探测与修复

摘要

According to the characteristic of the three-frequency signal and its combination observation, a new method on non-difference observation value for detecting and repairing cycle slip is presented.This method is based on the combination of ultra-wide lane and ionosphere residual method.The location and size of cycle slip are ob-tained by solving the phase observation value of the BDS three-frequency carrier phase.The result showed the com-bined method can effectively detect and repair the different size cycle slip, and the cycle slip of three different types of Beidou satellite data can be detected with this method, and the method has higher accuracy and reliability.%根据北斗三频信号的特点及其组合观测值特性,详细阐述了一种新的非差观测值周跳探测与修复方法;该方法利用超宽巷组合(moulborne-wuebbena,M-W)组合观测值优点,对电离层残差法进行相应改进;并通过改进后的电离层残差法获取周跳的位置和大小.计算结果表明:该组合方法可以有效地探测和修复不同大小的周跳,而且适用于北斗三种不同类型卫星的信号处理,说明该算法具有较高精确性和可靠性.
