摘要
提出了一种新的全球定位系统/惯性导航系统(GPS/INS)组合方式。从频域角度对GPS码跟踪环及载波相位锁相环进行了数学建模,对INS辅助GPS码跟踪环、载波相位锁相环的方式进行了分析研究,指出这种组合方式的优点及缺陷,最后通过数学仿真验证了分析结果。
A novel tight integrated method is advised. Performance and integrated methods of INS-aided GPS tracking loops are studied on the base of modeling the Code-Lock Loop and the Phase-Lock Loop of GPS. The advantages and disadvantages of this new integrated method are pointed out. In the last, a mathematical simulation of INS-aided the Phase-Lock Loop verifies the analytic results.
