Abstract:	In this paper, anti-jamming performance of the INS velocity aiding tracking loop and the deeply coupled GPS/INS integration system were evaluated and compared. The INS velocity aiding tracking loops can have good signal tracking performance even though its bandwidth is not wide. In the deeply coupled integration system, conventional tracking loops are included in the integration Kalman filter. Due to this, it is difficult to evaluate anti-jamming performance. In order to compare anti-jamming performance, accuracy of the navigation result was investigated. The continuous wave (CW) were used as jamming signal for test. The simulation results show that the deeply coupled integration system gives better anti-jamming performance than the INS velocity aided tracking loop.
