Study on geomagnetic anomaly matching aided navigation

MA Biao,WANG Xiang-lei(Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 450052,China)  
The principle of geomagnetic anomaly matching navigation was presented in the paper,its key technologies were analyzed,system state equation and observe equation were built in the paper.Last,one application was presented,where data fusing was made using EKF.The simulation results indicated that geomagnetic anomaly matching aided navigation could revise INS error effectively,reduce navigation error greatly.
