| Abstract: | Extended kalman filter was used in position resolution of terrestrial radio navigation system. The state model and observation model of system were designed and constructed. At the same time the question of divergence of Kalman filter was presented and some methods were provided for the divergence of filter to improve the tracking precision of navigation. The simulation result is shown in the end of paper. |
