In order to realize the real-time measurement and control of geosynchronous orbit satellite during the process of global deployment,a TT&C scheme with comprehensive utilization of satellite-ground link and inter-sat-ellite link is proposed in this paper.Based on the two stages divided by the scheme,wherein one is in the view stage and the other one is out of sight stage,a time-sharing heterogeneous architecture is constructed.In this archi-tecture,satellite-ground link is mainly used in stage one when ground station can control satellite directly,and in-ter-satellite link is the only way to measurement the object when it is out of the ground station visual range.A varie-ty of different inter-satellite links,such as inter-satellite link with observation-data-relay satellite and TDRS/BD in-ter-satellite link,are utilized.Furthermore,the communication link budget is calculated and the mission reliability is analyzed.The result shows that the scheme is feasible and reliable.
