INS/GPS Integrated Navigation Method Based on Neural Network

Abstract:

Inertial Navigation System (INS) and Global Positioning System (GPS) are commonly integrated to overcomes each systems inadequacies and provide an accurate navigation solution. However, the positioning accuracy deteriorates with time in the absence of GPS signals. This paper proposed an artificial neural network aided INS/GPS integrated navigation method to bridge the GPS outages. In this method, the neural network was trained to model the error of INS when GPS was available. INS velocity and attitude error were got by implementing the neural network when GPS outages occurred. Simulations in INS/GPS integrated navigation showed improvement in positioning accuracy for GPS outages.
