Construction of an integrated space-ground spacecraft TTC(Telemetry,Tracking and Command)and communication network using internet technology is critical to integrated space information application,which is an evitable trend of development in the field of spaceflight.As a public services platform for transmission and dissemination of space information,the integrated space-ground spacecraft TTC and communication network facilitates unified command and control of TTC and communication missions,display of spacecraft status,integrated use of TTC and communication resources and sustainable development while all spacecraft,fixed and mobile stations on earth and in space,spacecraft control centers,customers,etc.are standard nodes in such a network.Following a summary of research results home and abroad,the paper proposes definition and future architecture of integrated space-ground spacecraft TTC and communication network and steps of implementation.An associated spaceflight test plan is also given together with a list of key technologies for development of an integrated space-ground spacecraft TTC and communication architecture.
