To improve precision of double-star positioning system (DSPS) in China and overcome the defects due to the shadiness of DSPS in the war, an indirect Kalman filter-based loosely coupled method for tri-star passive BeiDou/Global Positioning System (BeiDou/GPS) integrated navigation system is presented. This chapter uses tri-star passive positioning technique to solve the shadiness of DSPS in the war. An indirect Kalman filter-based method is proposed to combine BeiDou with GPS to fuse into an integrated navigation system to enhance precision of BeiDou when GPS is available. Experimental results demonstrate that the proposed Kalman filter-Based method can effectively reduce the positioning error, and precision of the BeiDou/GPS integrated navigation is better than GPS-only navigation.
