Design of Integrated GPS/DR Orientation System Based on Double CPU

In order to keep pace with the rapid development of the integrated GPS/DR orientation system, the integrated GPS/DR orientation system based on double CPU is put forward in this paper. Where gives an introduction of the hardware composition of this system. A new federated filter algorithm is proposed in the integrated GPS/DR orientation system, which is made up of the Kalman filter and the unscent Kalman filter. The simulation results show that the proposed method has better performance than the traditional federated Kalman filter.
