光学侦察卫星任务时效性评估研究

Evaluation for Mission Timeliness of Optical Reconnaissance Satellite

摘要:

卫星任务时效性直接影响卫星的任务效益,针对光学侦察卫星任务流程,详细分析任务相关环节并建立了数学模型;从时间链上对侦察卫星姿态调节时间、过境时间、数据下传时间三个任务环节进行了仿真计算,并比较了多颗卫星对具体观测任务的相关时效差异以及相关影响因素,有效反映了侦察卫星任务效能,为光学侦察卫星任务时效性分析及效能评估提供了依据,对卫星观测任务方案时间任务效能分析预评估有重要的应用价值。

Abstract:

The timeliness of satellite mission directly affects the efficacy of satellite. Aiming at the task process of optical reconnaissance satellite, detailed analysis of the relevant aspects of the task and established mathematical model. The simulation calculation of reconnaissance satellites' attitude adjustment time, transit time and data transmission time is carried out, and compared the relative difference of the multi-satellite to the specific observation task, effectively reflected the reconnaissance satellite mission efficacy, which provides a basis for the timeliness analysis and efficacy evaluation of optical reconnaissance satellite missions.
