Present status and development trends of multi-spacecraft TT&C

With the increasing number of spacecraft in orbit,multi spacecraft simultaneous telemetry,tracking and command(TT&C) has become an important aspect in the construction and development of space based and ground based TT&C network.Through summarizing various multi spacecraft TT&C methods, it is concluded that multi beam antenna technology is the main direction of multi spacecraft TT&C.The current methods based on multi beam and their future research direction are reviewed from space based and ground based aspects,and the multi spacecraft TT&C management mode based on the feed link of foreign giant constellation is analyzed.Then the concept and development of random access TT&C mode are discussed.According to the development status of Space ground Integration Information Network,the characteristics of multi spacecraft TT&C in the network are analyzed.
