摘　　要：大规模星座入轨段测控对卫星安全至关重要,但同一地面站同时支持的卫星数量有限。为解决大规模星座发射入轨段地面测控资源不足的问题,文章首先介绍了目前一箭多星的入轨段测控方法,然后从天基测控支持大规模星座入轨的可行性和可靠性角度出发,对中继卫星的能力和中继测控终端的设计进行了研究,提出一种利用天基测控实现多星入轨段测控的方案。该方案详细分析了大规模星座卫星入轨初期测控链路的影响因素,并给出一种综合利用软件仿真结果和星上自主计算结果的稳定可靠的入轨段天基测控方案。该方案仅需在现有中继测控终端使用方法基础上进行适应性更改即可满足多星入轨需求,方法简便易实现。TT&C for orbit insertion phase of satellites is crucial,but the number of satellites that can be supported simultaneously by a single ground station is limited.In order to solve the problem of insufficient ground TT&C resources for large constellation satellites during orbit insertion phase,TT&C methods during orbit insertion phase for multiple satellites launched by a single rocket are firstly introduced.Then from the perspectives of feasibility and reliability of space-based TT&C,research is conducted on the capabilities of relay satellites and the design of space-based relay TT&C terminals.Factors that influence TT&C links during orbit insertion phase are thoroughly analyzed.A stable and reliable space-based TT&C solution that utilizes software simulation results and onboard independent real-time calculations is proposed.The proposed solution can meet the requirements of multi-satellite orbital insertion by making adaptions to the existing usage methods of relay TT&C terminals.It is a versatile approach that can be easily realized.
