STADAN stations were located in the following areas around the world:
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.3 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.
