摘要：

A GPS/INS integrated navigation system is designed and errors caused by the acceleration of the vehicle and the INS are being modeled mathematically. In this paper, a data-fusion algorithm is used to improve the accuracy of the GPS/INS navigation system. Practical data has shown this algorithm could prevent the integrated system malfunctioning when the GPS receiver has lost the track of the positioning signals. In such a way, the method we used could enhance the GPS/INS integrated system reliability and robustness when the system is being used in the environment where a lot of tall buildings are located.
