Application of multi-sensor information fusion technique in interated navigation system
Xing Huo · Journal of Bohai University · 2008
Aiming at the problem that much data processing calculation and failure data interaction each other of INS/GPS integrated navigation system,this paper proposed one navigation parameter optimal estimate filter method based on information fusion.First,the postulate,key technology and usual method of information fusion;second,ING/GPS combination as example to analysis running principle and model establishment;last,the multi-sensor information fusion arithmetic based on federated Kalman filter,which may improve the calculational precision and speed which has beter fault tolerance and environment adaptability,may help for improving the precision and reliability,and provide a avaiable approach for the data analysis and procession of fusion navigation system.Expatiation above has practical value.
