Study of GPS/DR Integrated Navigation System for Vehicle

  • Received Date: 29 Apr 1998
  • Publish Date: 31 May 1999
  • The design of the GPS/DR integrated navigation system is presented and the main error sources which affect the GPS/DR system position accuracy are also analyzed. A mathematical model is founded to represent these main errors and an extended,iterated and federated Kalman filter algorithm is propounded which is based on compensating for some observation errors according to the principle of data fusion of the GPS/DR integrated system for vehicle. The Experimental results demonstrate that this filter algorithm can improve the positioning accuracy of the GPS system , correct the accumulating error of the DR system at the same time, and enhance the GPS/DR integrated system reliability and integrity greatly.
