摘要： 双星定位系统是一种区域性定位系统。介绍了双星定位系统的定位原理 ,说明了其存在的定位实时性较差的不足。对此提出了利用惯导经卡尔曼滤波器校正后的输出速度信息来修正双星定位系统的输出水平位置信息 ,然后与惯导进行组合 ,建立了其状态方程与观测方程。仿真结果证明该方案切实可行 ,对双星定位系统的实际应用有重大的理论参考价值

Abstract: Double star position system is one kind of regional position system build up. The position principle of Double star position system is introduced, and its shortcoming that is the bad real time of position is explained. For this fact one scheme that the output velocities of SINS after revised by the Kalman filter modify the output level positions of Double star navigation system is put forward, then the Double star position system is integrated with the inertial system, and the state and measurement equations are build up. The simulation results demonstrate this method is feasible, and has an important theoretic value for the practical use of the Double star navigation system.
