基于LabVIEW与STK的卫星轨道预报可视化仿真平台设计

摘要

A method of designing a satellite orbit prediction visualization platform based on a hardware-in-loop validated simulation system of small satellite is introduced. Satellite Tool Kit is an analysis software widely used in simulating orbit system for satellite, but STK can' t accomplish the relevant function that acquired by the hardware-in-loop validated simulation system mentioned. Based on this requirement, a method of using ActiveX technology in LabVIEW and STK/Connect module to interact the two kinds software is introduced. Through calling STK and u-sing Connect module in STK to obtain the relevant data, finally all the datas in need within a window synchronously can be displaied, which realized the connection between LabVIEW and STK , also accomplished the relevant function and has a applied value.%介绍了在小卫星半实物仿真系统的背景下一个卫星轨道预报可视化仿真平台的设计方法.卫星工具软件(STK)一般用于卫星轨道的可视化仿真中,但仅用STK软件无法满足该小卫星半实物仿真系统关于轨道节点的要求.基于此点,利用LabVIEW的ActiveX模块以及STK的Connect模块实现两种软件交互的方法,通过LabVIEW的ActiveX功能连接STK,利用Connect模块中的指令驱动STK产生卫星的相关数据,最终将有关数据返回至LabVIEW中并显示出来,实现了LabVIEW与STK的无缝连接,完成了卫星半实物仿真系统的相关功能,具有一定的应用价值.
