基于公式和图表等进行航天器轨道设计方案的评估与验证存在理解困难和评审效率低的问题,为此基于STK与MATLAB提出一种航天器实时变轨仿真策略。以导弹为研究对象,建立弹道计算引擎,采用计算即发送的方式将弹道点发送至STK,同时建立弹道辅助显示对象,使仿真兼具实时性与对照性,以直观的展示变轨效果。试验结果表明:本策略能够准确可靠的实现航天器实时变轨仿真,可用于轨道设计方案的评估与验证。

Evaluating and validating the design scheme of spacecraft trajectory based on formula and chart causes difficulty in understanding and reviewing. Therefore, a simulation strategy of spacecraft real-time maneuver was proposed based on MATLAB and STK. With the missile as research example, the trajectory computing engine was established, which sent the trajectory data to STK in a specific way and at a certain speed. Meanwhile, the trajectory auxiliary display object was created, ensuring the simulation met the real-time and contrast requirement and showed the effect of maneuver. The simulation results show that this strategy can realize real-time maneuver simulation accurately and reliably and can be used for the simulation and verification of spacecraft trajectory design.
