Abstract:
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.
