基于STK的卫星入轨主动段仿真显示设计

Design of Sim ulation Display of STK-Based Boost Phase in Satellite Launching

在卫星入轨主动段过程中,接收存储弹道测量数据,剔除弹道数据中位置跳变数据和轨迹跳变数据,利用用户识别应用发展工具(STK)命令更新运载火箭位置,设置火箭模型动作,实现了弹道测量数据和火箭动作时序的可视化显示。在深入研究STK的基础上,设计了基于STK的卫星入轨主动段仿真显示应用程序,能够直观、逼真的反映卫星入轨主动段内运载火箭的飞行轨迹和一级分离、星箭分离等动作,对于主动段弹道数据分析和显示起到了很好的辅助作用。

During the boost phase ofsateUite initial entering orbit, the trajectory data are received and stored, the position hopping data and track hopping data are eliminated, the Sire Tool Kit （STK） command is used to update launch vehicle position, the launch vehicle model＇s action is set, and the visual simulation of trajectory data and launch action schedule is realized. This paper studies the core technique of STK, develops the program of Simulation Display of STK-Based Boost Phase in Satellite Launching. The simulation results show that this method can more realistically and more lively reflect actions of launch vehicle in the boost phase such as flying track, first-stage separation and space vehicle separation, has a great effort to improve the analysis and visual simulation of trajectory data.
