Abstract :
To solve shortcomings of federal Kalman filter from calculating inverse matrix of the error variance matrix, a new fusion algorithm based on trace of error variance matrix is presented. Theoretic analysis and simulation results demonstrate that the method is an effective solution to the shortcomings and improves real-time performance and fault tolerant of integrated navigation system.
