The 148 SOPS mans the Milstar Operations Center-Vandenberg (MOC-V), one of two fixed Milstar Ground Stations. Unique to Milstar is its ground segment for control of the constellation. Milstar has two fixed ground stations, Milstar Satellite Operations Center (MSOC), at 4 SOPS and Milstar Operations Center – Vandenberg or MOC-V. Each site is fully capable of complete constellation control and operates 24/7. The Milstar Ops Center-Vandenberg is operated by the 148th SOPS, a California Air Guard Unit, and does control 2 Milstar satellites full-time.
The 148th SOPS was originally established as the 148th Combat Communications Squadron at Compton, California. The unit was redesignated the 148th Space Operations Squadron, and relocated to Vandenberg AFB, California on 31 October 2000.
