Abstract: The central management and unified allocation mode applied to the space TT&C((telemetry),tracking and command) network,as well as the scheduling algorithms to meet multi-satellite TT&C missions are analyzed in the paper.A balanced scheduling algorithm is presented.Firstly,satellite TT&C missions are divided into different priorities and the TT&C stations are(allocated) according to the mission-oriented principal of optimization in order to support the(maximum) of missions as possible.Based on this result,re-optimization should be implemented to balance the workload of each station considering the workload and backup of TT&C stations.The presented scheduling algorithm takes account of success probability of satellite TT&C missions and makes the designated workload of each station more balanced than other algorithms.It is convenient for managing space TT&C network.
