摘　　要：在总结神舟载人飞船测控模式发展演进规律的基础上,基于当前国内外低轨卫星星座蓬勃发展的趋势,文章提出了一种基于低轨互联网星座进行载人飞船测控的模式构想,通过对初步互联网星座方案构想下开展神舟载人飞船测控能力的仿真分析,得出该测控模式可将飞船最长站外时间降低至2 min,大幅提升应急处理能力和测控系统冗余,减少传统地面测站和中继资源占用,从而降低测控成本,提高测控效益,是未来测控模式演进的选择之一。The paper first reviews the development and evolution of TT&C modes for Shenzhou manned spacecraft.Then,a new TT&C mode for Manned spacecraft is proposed using LEO Internet Constellation,since its highly developing trend all over the world.Through the simulation analysis,the new TT&C mode can reduce the maximum revisit time to 2 minutes and enhance emergency response capacity.More importantly,the new mode can reduce TT&C cost and improve TT&C benefits significantly by reduce the occupation of ground station,surveying ship or tracking and data relay satellite resources,making it an prospective option of future TT&C mode.
