摘　　要：相比地基测控站,以中继卫星为代表的天基测控资源,对于近地卫星跟踪任务具备极大的优势。本文分析了近地卫星的跟踪特点,分析了天地测控资源本身的使用能力,采用通用的资源分配软件模拟计算天基、地基资源对低轨星群的跟踪能力和效率,提出了适合测控资源的任务比例,作为测控资源分配时的参考。As a typical representative of space-based TT&C resources,a tracking and data relay satellite has numerous advantages over ground TT&C stations for LEO satellite missions.This paper presents analysis and simulation to make full use of both space-based and ground-based TT&C resources space missions.With a general resources allocation tool,the tracking characteristics of LEO spacecraft are analyzed and the capabilities of tracking and data relay satellites and ground TT&C facilities are respectively estimated.simulation and allocation of each TT&C resources with different mission loads are performed and the tracking efficiency of the resources is computed.
