Method of navigation resource management based on efficiency function

In order to improve the performance of the integrated navigation system, a new navigation resource management method based on an efficiency function is proposed in this paper. Firstly, the framework of the navigation resource management method is established. Secondly, the representation of the efficiency function is given, which based on the navigation accuracy, the sensor accuracy and the navigation task. Finally, this method is simulated and compared to the traditional data fusion method. The simulation results show that the positioning accuracy and the computing time of this method are improved by 20.1% and 26.7%, respectively. This method makes full use of the sensor accuracy, and manages the navigation resource effectively. It effectively improves the navigation accuracy and the computational efficiency.
