For the purpose of mastering the overall health state of the ground-based Tracking,Telemetry and Command (TT&C) networks,a health evaluation model for ground-based TT&C networks is established based on the characteristics of ground-based TT&C networks.A method using the difference between measured value and standard value of indexes to evaluate indexes is proposed.The indexes of three modules (control center module,TT&C nodes module and communication links module) that can influence the health state of ground-based TT&C networks is analyzed.The weight of each evaluation index for the evaluation model using Analytic Hierarchy Process (AHP)is determined and standard value for each index in operation of ground-based TT&C networks is given.Based on 2015 S-band TT&C equipment and on-orbit spacecraft to evaluate the health status of S-band ground-based TT&C network in China,the evaluation results are that the health index was 88.32％ and the health level was good.The results show that the proposed evaluation method can determine the health status of ground-based TT&C networks directly and can be used in operation management of TT&C networks.
