| 摘 要： | 载波观测值由于其高精度的特点,在北斗高精度导航与定位中应用广泛。周跳的存在严重污染了载波观测值,在北斗高精度导航和定位中必须予以消除。本文基于北斗B1载波和B2载波相位观测值的关系,通过相邻历元的相位观测值求差值探测周跳,并结合伪距差分约束条件确定及修复周跳,有效解决周跳值解算多解问题。结合实验数据模拟分析,证明该方法可以有效探测并修复北斗载波观测值周跳。

| Abstract: | Due to its high accuracy,the carrier observation value is widely used in the BeiDou navigation and positioning. The existence of the cycle slip seriously polluted the carrier observation value,and it must be eliminated in the BeiDou navigation and positioning. Based on the analysis of B1 and B2 carrier-phase observation values,using the phase difference between adjacent epochs to detect cycle slip,and combining the pseudo-range differential constraints to identify and repair the cycle slip. Through the case study,the method can effectively detect and repair the BDS cycle slip. |
