基于中继卫星多址支持的卫星在轨健康管理模式

A Concept of Satellites’ Health Management Based on TDRS SMA

智能化卫星在健康管理方面提出了随遇接入中继卫星系统为其提供测控的要求,基于中继卫星S频段多址SMA全景波束支持,本文提出了一种中低轨卫星在轨健康管理的新概念和模式.新模式系统由中继卫星、用户终端和地面系统构成,分析给出了卫星在轨全时监视及随遇接入、卫星快速抢救、问题排查归零的健康管理工作流程,实现该模式运行的关键技术主要包括用户星在轨健康管理技术、基于中继卫星S频段多址的全景波束技术和空间网络接入技术。为后续中继卫星系统测控发展应用提供了一种新思路.

In order to satisfy the requirements, using tracking and data relay satellite system(TDRSS) at anytime and anyplace, for the monitor of intellectualized satellites health management, a concept of satellites’ health management was proposed based on tracking and data relay satellite(TDRS)S-band multiple access(SMA). The new system was arranged to be composed of the TDRS, terminal equipments on satellites, and the ground equipments. A working process of health management was designed, including health information transmission, controlling SOS satellites quickly and solving the question three periods. Some key technologies were carried out for the new system, mainly including satellites’ health management, panoramic beam and space network access based on TDRS SMA. The new mode can provide a new approach for the development of TT&C by subsequent TDRSS.
