摘　　要：原子干涉测量技术可以获得极高的惯性测量精度。本文简要介绍了原子干涉仪的工作原理,在此基础上介绍了其在重力匹配辅助导航技术的原理与应用,同时设计了一种重力梯度匹配导航的结构与算法原理,指出原子干涉惯性导航技术具有高精度、高效率、无需外部信息校正的无源导航等优点,可最终解决水下潜器长时间的自主导航需求。The measuring technique based on atom intefferometer can acquire inertial measurement with extreme high precision. The operation principle of atom interferometer was presented in the paper. The principle and application of gravity matching aided navigation were introduced; structure and principle of algorithm for a kind of gravitational gradient matching navigation were designed. The inertial navigation based on atom interferometer has many merits as high efficiency, high precision, passive navigation with no extraneous information calibration, the long-term autonomous navigation of underwater vehicle could be resolved uhimately.
