• 11 civil organizations including
  • 6 stations operated by the National Geospatial Agency and
  • 5 from the National Geodetic Survey

The main task of the stations is the tracking (continuous tracking) of all visible satellites, u. a. through distance measurements , the transmission of data ( synchronization of time and orbit data) and system commands to the satellites. The Master Control Station (MCS), the main control station, is located in Colorado Springs , with a second, alternative station at Vandenberg Air Force Base , California.
