中文摘要：
车载武器系统行进间初始对准的性能对提高武器系统生存能力有着重要意义。对已有的几种车载捷联惯导行进间对准方法进行论述,并对其适用性进行分析。在此基础上,设计了一种自主式车载捷联惯导行进间对准方案。将里程计航位推算得到的位置信息和利用电子地图进行地形匹配得到的位置信息分别作为观测量,经过分散式信息融合方法,使车载捷联惯导系统能够满足复杂车况下行进间对准快速、精确的要求。
英文摘要：
The performance of in-motion alignment for land-vehicle weapon system plays an important role in improving the survival capability of weapon system. Several strapdown inertial navigation system （SINS） in-motion alignment methods for land-vehicles are discussed, and their applicability is analyzed. Based on these, an autonomous SINS in-motion alignment scheme for land-vehicles is designed. The posi- tion information reckoned by odometer and the position information got via terrain matching algorithm are re- garded as the estimation information. Through multiple information fusion by distributed filtering, the land- vehicle SINS can meet fast and accurate demand of in-motion alignment under complex marching environment.
