陆用惯性导航系统为陆军**平台及载体提供自主定位定向和运动状态测量手段，是战场统一坐标基准的保证和陆军主战装备的重要组成部分。在论述陆用惯性导航系统特征的基础上，从陆用惯性导航及组合导航技术体制出发，分析了陆用导航技术工程应用中面临的问题，分别阐述了针对这些问题国内外学者主要采取的解决思路，列举了相应技术体制下的国外典型定位定向装备，以此对未来陆用惯性导航系统的发展趋势做出展望。

The land inertial navigation system provides autonomous positioning，orientation and motion measurement methods for the Army‘s weapon platforms and carriers. It is a guarantee for the unified coordinate reference of the battlefield and an important component of the Army’s main battle equipment. Based on the characteristics of the land inertial navigation system，starting from the land inertial navigation and integrated navigation technology system，the problems faced in engineering application of the land navigation technology are analyzed in this paper. The main solutions for these problems by the domestic and foreign scholars are expounded. And the foreign typical positioning and orientation equipment under corresponding technology are enumerated. In this way，the development trend of land inertial navigation system in the future is prospected.
