The 'Air Force Satellite Control Network (AFSCN)' provides support for the operation, control and maintenance of a variety of DoD and some non DoD satellites. This involves continual execution of the tasks involved in Tracking, Telemetry and Command (TT&C). In addition, the AFSCN provides prelaunch simulation, launch support and early orbit support while satellites are in initial or transfer orbits and require maneuvering to their final orbit. The AFSCN provides tracking data to help maintain the catalog of space objects and distributes various data such as satellite ephemeris, almanacs, and other information.
