摘要: 惯性导航作为一种战时能全面提供导航信息的可靠手段在一定时段内能保证精度，但由于惯性器件漂移的影响，其导航精度难以满足舰载武器长航时需求；星光导航以宇宙中具有精确空间位置的天体作为导航信标，其精度主要取决于光轴测量精度，无时间累积误差。本文讨论惯性/星光导航技术中，利用星光导航误差有界性特点克服惯性导航误差随时间发散的缺点；同时惯导将持续提供高精度水平基准给星光导航系统，采用基于星光系统位置和姿态信息的互补手段，解决星光导航精度受制于惯性水平基准的问题，构造高精度水平基准，保证星光误差的有界性，从而保障星光量测信息的准确性。
Abstract: Inertial navigation, as a reliable means that can provide navigation information in a certain period of time, can guarantee accuracy, but due to the influence of inertial device drift, its navigation accuracy is difficult to meet the needs of ship-borne weapons when long-haul. This paper discusses the inertial/starlight navigation technology, using the boundary characteristics of starlight navigation error to overcome the shortcomings of inertial navigation error with time, while the inertial guidance will continue to provide high-precision horizontal reference to the starlight navigation system, using complementary means based on the position and attitude information of the starlight system, to solve the problem of starlight navigation accuracy subject to inertial horizontal reference, to construct high-precision horizontal reference, to ensure the boundary of starlight error, so as to ensure the accuracy of starlight measurement information.
