摘要
在卫星导航接收机跟踪载波信号过程中,经常会由于树木房屋遮挡等原因导致周跳发生。针对双天线组合导航的场景,参与组合的惯导姿态信息若能充分利用,可以对周跳探测提供更为精确的辅助信息。文章提出一种INS/载波相位组合法,通过惯性测量信息辅助周跳探测与修复,进而缩短导航信号失锁时间,提升卫星导航系统性能,优化组合结果。
In the process of tracking carrier signal by satellite navigation receiver,cycle slip often occurs due to the occlusion of trees and houses or other reasons.In the scenario of dual-antenna integrated navigation,attitude information of the inertial navigation system can be fully utilized to provide more accurate auxiliary information for cycle slip detection.This paper proposes an INS/Carrier Phase Combination Method,which assists cycle slip detection and repair through inertial measurement information,thereby shortening the time of navigation signal loss-of-lock,improving the performance of the satellite navigation system,and optimizing the combination result.
