Simulation Method Study of Strapdown Celestial Guidance
Pages: 51-57
Year: Issue:  2
Journal: Aerospace Control

Keyword:  Combined guidance Star tracking guidance Simulation technique;
Abstract: 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.
