Research on TT&C strategy of Long-term Management of Constellation Satellites in Orbit

摘要:

近年来，低轨大型卫星星座蓬勃发展，使得在轨卫星数量急剧增加，卫星在轨长期管理任务面临巨大挑战。首先分析了卫星星座在轨长期管理面临的挑战，针对星座卫星在轨长期管理面临的几种常见应用场景，通过理论分析扩频体制测控应答机的抗干扰机理，结合地面概念星卫星平台模拟验证，在微波暗室通过地面概念星卫星平台对星座卫星在轨长期管理肯能出现的情况进行模拟。模拟不同星座卫星在轨运行场景以及相应的测控应对策略，验证了多星同时入境时的卫星长期管理策略的可行性，给出星座卫星在轨长期管理的有效应对策略。为卫星在轨长期管理以及后续可能遇到的星座在轨长管问题提供参考。

Abstract:

In recent years, the low-orbit large-scale constellation satellites has flourished, resulting in a sharp increase in the number of satellites in orbit. Firstly, the challenges of long-term management of satellite constellation in orbit are analyzed. According to several common application scenarios of long-term management of satellite constellation in orbit, the anti-interference mechanism of TT&C transponder with spread spectrum system is analyzed theoretically. Combined with the simulation verification of ground concept satellite platform, the situation that long-term management of satellite constellation in orbit can appear through ground concept satellite platform in micro wave darkroom is verified The simulation is carried out. Simulation of different constellation satellite in orbit operation scenarios and the corresponding measurement and control response strategies verify the feasibility of the satellite long-term management strategy when multiple satellites enter the country at the same time, and give the effective response strategy of constellation satellite in orbit long-term management. It provides a reference for long-term satellite in orbit management and subsequent large-scale constellation rail long tube problems that may be encountered.
