摘要
针对天地一体化任务的实际需要,建立了卫星轨道计算与升空平台时空特性分析模型,在卫星轨道计算与星地可通信性分析的基础上,提出了升空平台执行天地一体化任务的时空条件分析以及升空平台的任务执行时机和位置的选取方法。以无人机作为升空平台,构建并实现了升空平台用于天地一体化任务的时空覆盖分析与仿真程序。验证了仿真程序的轨道计算数据的可用性,并对仿真结果中的无人机航迹数据进行了比较与分析。
Satellite orbit calculation, as well as analysis model of blast-off platform＇s time and space characteristic, was established. Analysis method of time and space qualification for blast-off platform, which was used for space-earth integration task, and selection method of time and position for implementing the task, was proposed. Finally, taking the unmanned aerial vehicle （UAV） as blast-off platform, simulation system about space-earth integration task was realized. And the usability of orbit calculation data was demonstrated, and the UAV＇s flight path data was compared and analyzed.
