Use of Extended Interval Kalman Filter on Integrated GPS/INS System

X. F. He and B. Vik

Abstract:	GPS/INS integration with uncertain dynamics modelling and uncertain measurement noise is studied. An extended interval Kalman filter is applied to such an uncertain integrated system, since the traditional extended Kalman filter is no longer applicable. The results of a computer simulation indicate that the extended Kalman filtering algorithm is consistent with the traditional extended Kalman filtering scheme, and is also effective for the nonlinear integrated system with uncertainty.
