介绍舰空导弹垂直发射与捷联惯性导航系统两者的关系,指出要完成垂直发射,惯性初制导必须由导航和制导控制两部分组成.对平台式与捷联式惯导系统作了比较,分析了它们各自的优缺点,且较详细地叙述这两种系统的组成、作用和工作原理;给出了速率捷联惯导系统的方案组成及数字仿真结果.最后介绍捷联惯导系统的关键研制项目,它们是:大量程高精度的速率陀螺、弹上快速运行微型计算机、数学模型、程序设计和半实物仿真试验.
This paper introduces the relationship between the vertical launch of ship-to-air missiles and the strapdown inertial navigation system, and points out that in order to complete the vertical launch, the inertial primary guidance must be composed of navigation and guidance control.Through the comparison between platform and strapdown inertial navigation system, Analyzed their respective advantages and disadvantages, and described in more detail the composition, function and working principle of the two systems; provided the scheme composition and numerical simulation results of the rate strapdown inertial navigation system.Finally introduced the SINS Key R & D projects are: large-scale, high-precision rate gyroscopes, fast-running microcomputers, mathematical models, programming and semi-physical simulations.
