| Abstract: |
| In order to deal with the shortage of space telemetry,tracking and command（TT&C） resources and the high complexity of planning and scheduling in the future,according to the current situation of TT&C network in China and the construction requirements of space-ground integration TT&C network,the basic framework is constructed.Referring to the random access mechanism of ground cellular mobile communication systems,random access TT&C is designed,and its basic idea is introduced,an example of implementation process in the new form is given,the protocol stack system of random access TT&C is designed,and the key technologies are discussed for reference of further research,including spacecraft access optimization selection strategy,panoramic(airspace) multi-beam and multi-target simultaneous TT&C technology. |
| Key words: space TT&C network space-ground integration random access TT&C;multi-beam TT&C |
