摘要： 针对平流层飞艇的飞行特点,提出了SINS/GPS/陆标组合导航方法,给出了SINS/陆标组合导航的观测模型,并将Sage-Husa自适应滤波方法与联邦滤波相结合形成改进的自适应联邦滤波,用于SINS/GPS/陆标组合导航系统。数学仿真结果表明:新组合导航系统相对于SINS/GPS组合导航系统,可以有效改善平台误差角的估计精度,同时利用改进的自适应联邦滤波可有效提高全局滤波精度。

Abstract: SINS/GPS/Landmark integrated navigation system was proposed according to the flight characteristic of the stratospheric airship.The observation equation of SINS /Landmark integrated navigation system was deduced and the improved SageHusa adaptive filtering method combined with federated filter was applied to SINS/GPS/Landmark integrated navigation system.Simulation results show that this new integrated navigation system can improve the attitude precision effectively relative to SINS/GPS integrated system and the improved adaptive federated filter can enhance the global estimation accuracy.
