摘要
介绍了卫星工具箱软件(Satellite Tool Kit,STK)的主要功能及其在航天领域的应用。在介绍该功能和特性的基础上,深入研究了STK的接口模块STK/X,并利用VC对STK/X模块进行了二次开发,实现了STK与VC软件的集成,完成了卫星编队系统的建模与仿真。根据仿真结果分析了卫星编队系统中卫星数目与系统信息传输时效性的关系,该仿真方法对卫星编队系统的设计具有参考价值。
This paper introduces the major functions of Satellite Tool Kit（STK） and its application in spaceflight field firstly.Based on the introduction to functions and characteristics of STK,the paper gives full analysis to the STK/X module of STK,makes secondary development of STK/X module using VC and realizes the integration of VC and STK as well as completes simulation and analysis of satellite formation system.According to the simulation result,the paper analyzes the relation of system information transmission timeliness with satellite number in the satellite formation system.This simulation method is of reference value for satellite formation system design.
