惯性导航传递对准技术发展现状与趋势

Development of Transfer Alignment for Inertial Navigation Systems

惯导技术具有完全自主、高度隐蔽、数据频率高等特性,因而在军事上得到广泛应用。传递对准技术是惯性导航的关键技术,对于保证精确制导武器搭载的以惯导为主的导航系统的精度具有重要意义。介绍了传递对准技术的基本原理,总结了传递对准技术中系统误差模型、匹配方式、可观测性分析、误差补偿、滤波方法等方面的理论和方法。归纳了近年来传递对准技术研究的进展,探讨了传递对准技术未来的发展方向。

As inertial navigation is completely autonomous,highly covert and has a high data frequency,and it is widely used in military technology. Transfer alignment is the key technology of inertial navigation and it’s important to assure the accuracy of inertial navigation system used in guided munitions. The developing status of transfer alignment was introduced by following aspects： system model,matching method,observing,compensation method and filter design. The research progress of transfer alignment technology in recent years was summarized. The possible developments in the future were discussed.
