Operations Building The Operations Building is the main control center, containing administrative support activities and the computer support equipment for telecommunications. The Operations Building was one of the first facilities constructed at the FCDAS, formerly known as the Gilmore Creek Tracking Station, in 1961. It was expanded in 1966, 1971, and 1973. The Operations Building also contains a boiler plant that heats water and mechanical equipment that serves the entire FCDAS.

Because the aged Operations Building has largely outgrown its operational and technical system carrying capability, a new Operations Center is planned for construction in the future.

26-Meter and Backup Antennas The parabolic dish antenna with a diameter of 26 meters was one of the first station facilities installed with the Operations Building in 1961. It supported the Nimbus weather satellite program operated by NASA. A 12-meter parabolic dish antenna was constructed around 1965 to download data from polar-orbiting weather satellites when the 26-meter antenna was unavailable. The antennas receive data transmitted from the polar-orbiting satellites.

Range & Range Rate In 1965, the Range and Range Rate Building and an antenna with a diameter of 9 meters were constructed by NASA to track the locations of satellites. Radio signals received by the 9-meter antennas to allow triangulation of the satellites' positions in space.

13-Meter Antennas Three 13-meter parabolic dish antennas were installed in 1998. They track, command, and receive data from NOAA and Department of Defense low-earth orbit satellites. They are a heavy duty, all-environment system offering precision pointing and auto-track accuracy. They track low altitude satellites and high velocity sources.

Vehicle Maintenance & Storage Facility The new 16,000-square-foot Vehicle Maintenance and Storage Facility is where motor vehicles used to operate the FCDAS are maintained and repaired. It is located near the former Facilities Building.
