Answer» What is Spaceflight Tracking and Data Network mean?

The Spacecraft Tracking and Data (Acquisition) Network (STADAN or STDN) was established by NASA in the early 1960s to satisfy the requirement for long-duration, highly-available space-to-ground communications. The network was the “follow-on” to the earlier Minitrack, which tracked the flights of Sputnik, Vanguard, Explorer, and other early space efforts (1957–1962). Real-time operational control and scheduling of the network was provided by the Network Operations Control Center (NOCC) at the Goddard Space Flight Center (GSFC) inGreenbelt, Maryland.

Consisting of parabolic dish antennas and telephone switching equipment deployed around the world, the STADAN provided space-to-ground communications for approximately 15 minutes of a 90-minute orbit period. This limited contact period sufficed for unmanned spacecraft, but manned spacecraft require a much higher data collection time. In May 1971 STADAN was consolidated with the Manned Space Flight Network (MSFN) to form the Spaceflight Tracking and Data Network (STDN).
