摘要
对北斗周跳探测与修复的问题,利用北斗卫星信号频率特征以及电离层残差法的基本原理,推导并构造了适用于北斗周跳探测与修复的周跳检验量,通过北斗实测数据和人为加入周跳的实验方案,对该周跳检验量进行验算.结果表明:电离层残差法能够较好探测和修复较小的周跳,适用于北斗周跳的探测与修复.
Aiming at the Beidou cycle slip detection and restoration, the paper, based on the Beidou signal frequency characteristics and the principle of the ionosphere residual method, derives and constructs the cy- cle slip detection observable that fits for Beidou cycle slip detection and restoration. Through the measured Beidou data and the experiment schemes with the cycle slip joined by people, the cycle slip detection ob- servable is calculated. The conclusion shows that the ionosphere residual method can better detect and re- pair the smaller cycle slip, and it is suitable for Beidou cycle slip detection and restoration.
