摘要
为了提高绕地飞船的自主定位精度 ,又不至于增大定位系统的体积和重量 ,采用紧密组合方式构成GPS INS定位系统 ,研究了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 :建立的GPS INS组合导航系统模型既能保证定位的高精度 。
To improve the quality of the self-positioning of airship around the earth, and not to lead to the increasing of volume and weight of the positioning systems of airship, the GPS/INS integrated positioning systems are constituted with close integrated pattern. The paper researches its application in the self-positioning of airship around the earth. According to real state of the airship, this paper forms its error state equations and integrates observation 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.
