摘要
针对成百上千甚至上万颗卫星组成的大型复杂天基组网星座,单靠地面测控网难以满足对卫星实时管控的问题,以及单靠星座组网自主测控存在的长时间偏离地面基准(时间和空间基准)等风险,本文综合考虑地面测控网以及星间组网的优势,提出大型组网星座自主运行的平行系统方法。通过构建天地一体平行系统,在ACP框架作用下,形成以组网星座自主处理为主、地面平行系统支持为辅的天地一体平行运行机制,从而实现大型组网星座自主管控、自主观测、自主处理和自主监测等自主运行功能。研究结果表明,本文提出的方法在大型复杂星座的自主运行方面具有参考价值。
In view of the large and complex space-based network constellation composed of hundreds, thousands, or even tens of thousands of satellites, the ground-based measurement and control network alone cannot meet the problem of real-time satellite management and control, and the long-term deviation from the ground reference caused by the independent measurement and control of the constellation network alone(Time and space benchmarks) and other risks, this paper comprehensively considers the advantages of ground-based measurement and control network and inter-satellite networking, and proposes a parallel system method for autonomous operation of large-scale networking constellations. Through the construction of a space-earth integrated parallel system, under the action of the ACP framework, a space-earth integrated parallel operation mechanism is formed with the network constellation autonomous processing as the main and the ground parallel system support as a supplement, so as to realize the large-scale network constellation autonomous control, autonomous observation, and autonomous processing and autonomous monitoring and other autonomous operation functions. The research results show that the method proposed in this paper has reference value in the autonomous operation of large and complex constellations.
