Spacecraft Tracking and Data Acquisition Network

The Spacecraft Tracking and Data (Acquisition) Network 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) in Greenbelt, Maryland.

Later developments
Most of the STADAN stations were phased out in the early 1980s, as the Tracking and Data Relay Satellite System (TDRS), took over most of the work of tracking satellites in low Earth orbit. Another network, the Deep Space Network (DSN), interacted with crewed craft higher than 10,000 miles from Earth, such as the Apollo missions, in addition to its primary mission of data collection from deep space probes. ==See also==
