Research on Algorithms for Pseudolite Aided Land Vehicle Integrated Navigation System

The pseudolite aided integrated land vehicle navigation system has been proposed.The principle and system model of the SINS/odometer/pseudolite integrated navigation system has been studied.The Federated Kalman Filter has been designed and simulated.The simulation result show that the navigation error can be effectively decreased by the integration of pseudolite into the navigation system.The pseudolite is independent and its use has no negative effect to the rapidity and mobility of the vehicles,so the proposed method is feasible,especially for high precise navigation in a limited range.
