绕地飞船的INS/GPS组合测控定位系统

INS/GPS Integrated Positioning System to Airship around the Earth

根据 INS和 GPS的基本原理 ,充分利用它们各自的优点 ,构建了 INS/ GPS组合测控定位系统。研究了该系统在绕地飞船自主定位中的应用。根据绕地飞船运动的实际情况建立了误差状态方程和组合观测方程。仿真分析表明 :该 INS/ GPS组合测控定位系统模型既能保证定位的高精度 。

Based on the principle of INS and GPS,using fully their advantages,the paper establishes the integrated positioning system using INS/GPS and researches its application in positioning airship around the earth.According to moving state of the airship,this paper forms its error state equations and integrated observing equations.Simulation results show that the integrated positioning system not only can pledge its high positioning precision but also can adapt target's quick moving.
