摘要
目标访问计算技术旨在计算卫星对目标的访问时刻及对应姿态,是观测卫星管控领域重要的基础技术。目标访问计算速度直接影响卫星管控的时效性,对多星多目标筹划实时性影响较大。面向多星多目标筹划任务,提出了双层并行架构的高速目标访问计算技术。该技术通过在任务级和线程级并行,提高了观测卫星目标访问计算的实时性。实验结果证明了该技术在多星多目标筹划任务中的实时性和优越性。
Target access computing technology is designed to calculate the satellite’s access time and the corresponding satellite attitude,this technology is an important basic technology in the area of reconnaissance satellite controlling.The computing speed of target access directly affects the effectiveness of satellite management and control,and has significant impact on the real-time effect of multi-satellite multi-target planning.To meet the requirements of multi-satellite and multi-target planning,a high-speed target access computing technology is presented based on dual-layer parallel architecture.This technology improves the real-time performance of target access computing of reconnaissance satellites by realizing parallel tasks and threads.The experimental results have proved the excellent real-time performance and superiority of this technology in the task of multi-satellite and multi-target planning.
