Abstract:

In order to improve the accuracy of SINS(Strap-down Inertial Navigation Systerm).The optical SINS and the GPS(Globle Position System) have been the objects of the study,and adopt the kalman filtering algorithm,constituting of the integrated system.The simulation shows that  the integrated navigation system improves the precision of navigation system by correcting the subfilter of fset timely and reducing the subfilter model error.especially  overcoming filter diverging problem.

Key words: fiber optic gyroscope, strap-down inertial navigation systerm(SINS), integrated navigation;kalman filter
