摘　　要：为了给捷联惯性导航数字仿真系统提供实时导航参数及惯性元件的精确值,并为其导航解算提供比较基准,设计出了一种简单的基于捷联惯性导航系统的轨迹发生器。通过介绍轨迹发生器的总体设计思路,提出了对载体轨迹发生器的数学编排的推导,并对载体在不同运动状态下的轨迹输入进行定义,最后对设计的轨迹发生器进行仿真实验。通过仿真实验表明,此方法简单高效,具有一定的可行性,为捷联惯导系统仿真提供了依据。In order to provide the exoct value of the real time navigation parometcrs and auurate volues of in ertial ampoment for SINS cstrap-down inortial navigation syspom digital simulation and provide a berchmark for its navigation calculating,asimple traiectory generator which was bosed on the strpp-down inertial narjgatim syeston,was proposed.Through introducing the ovor audesign ideas of trajetory jenerator,ctputonond the derivation of nafliematial urrayyement to the carrior troiectiny generator and mode a definition to the arrier ude different motion state trojectory input in the meantime.Finauy,simytation of the design of trafectory generator nas been mode.According to the simulation result the proposed dea isstmple and efficient with cortain feasibility and can provide a basis for strap-down inertial nanigation system.
