捷联星光制导仿真方法研究

捷联星光制导方案是把星跟踪器安装在平台基座上，利用星跟踪器和平台框架角的测量信息解算出因初始定位定向误差引起导弹的落点偏差，由末助推控制系统完成弹道修正。有关捷联星光制导方案的地面仿真原理、方法、组成，选星及大气修正计算原则、地球旋转影响在本文中作了论述，并给出仿真原理框图、硬件设备组成和功能、接口要求以及系统工作程序框图。

Simulation Method Study of Strapdown Celestial Guidance

With the measured information of the platform gimbal sensors and the star tracker mounted on the platform base board, strapdown celestial guidance scheme solves for the impact point deviation of the missile due to the initial localization and orientation errors, then,the terminal boost coatrol system performs correction of the trajectory. The ground simulation principle, method and composition of the strapdown celestial guidance scheme, selection of stars, computing principles on atmospheric correction and earth rotation influence are presented in the paper. Moreover, the simulation principle block diagram, hardware composition and function, interface requirement and the system operating program block diagram are given.
