摘　　要：首先介绍SINS/GPS3种紧耦合模式(tightly coupled模式、ultra-tightly coupled模式及deeply coupled模式)工作机理,然后系统分析了各耦合模式的特点、动态适应性及抗干扰性能,最后通过设计的SINS/GPS紧耦合导航仿真验证平台,对3种紧耦合模式的工作性能进行了仿真验证,并给出了结论。The mechanisms of three S1NS/GPS tight coupled modes are introduced at first, namely tightly coupled mode, ultra-tightly coupled mode and deeply coupled mode. From the aspects of allti-jamming capability, accuracy, speedability and reliability, the characteristics and adaptabil- ity in dynamic environment of these modes are discussed in detail based on their features. At last, the conclusive sugges- tion is proposed with respect to the choice of these S1NS/GPS integrated modes in engineering application.
