摘要
航天器地面综合测试时,为了在测试数据显示基础上,动态展示航天器交会对接过程,验证交会对接飞行方案的正确性,为航天员手控交会对接训练提供支持,设计航天器交会对接仿真系统,给出交会对接仿真平台设计架构;通过对航天器建模、虚拟场景装配、模型驱动方法、阳照区/阴影区绘制、姿态和星下点轨迹计算方法研究,开发实现航天器交会对接仿真平台;平台由实时测试数据驱动,在航天器地面静态测试下,可以实时显示航天器三维飞行状态及星下点轨迹;目前,仿真平台已经应用于航天器地面综合测试过程中,同时,平台可以扩展支持航天器在轨飞行动态展示,丰富了航天器测试和监视手段,具有较高工程应用价值。
In spacecraft integrated test mission, based on the test data monitoring, the spacecraft rendezvous and docking simulation system is designed and the simulation platform structure is given to show the spacecraft rendezvous and docking process dynamiely, to confirm the correctness of the flight program, as well as to support astronaut training with manual control rendezvous and docking method. The spacecraft rendezvous and docking simulation software is developed based on studying spacecraft modeling, virtual scene assembling, model driving, lighting area and shadow area drawing, attitude and satellite ground track calculation. The software is driven by real--time test data, it can display the spacecraft three--dimensional flying state and satellite ground track in the ground captive test. Now, the software has been used in spacecraft ground integrated test and it also supports the dynamic display of orbit flight. The software enriches the methods of spacecraft testing and monitoring. It has good engineering application value.
