2nd Space Operations Squadron The 2nd Space Operations Squadron is a component of Positioning, Navigation and Timing Integrated Mission Delta, headquartered at Schriever Space Force Base, Colorado. Mission The squadron performs the command and control mission for the 37-satellite Global Positioning System constellations, providing precise, three-dimensional position, Navigation and Timing Information to military and civilian users around the globe by operating Navigation Satellite Timing and Ranging GPS, the military’s largest, and the world’s most widely used, satellite constellation. GPS is the world's premiere space based PNT system, capable of providing information simultaneously to an unlimited number of properly equipped users. Continuous GPS availability and unprecedented accuracy has resulted in widespread integration of the technology; numerous military, commercial and international users have embraced GPS. The squadron operates the largest Department of Defense spacecraft constellation via the Master Control Station and worldwide network of monitor stations and ground antennas. The monitor stations track the satellites' navigation signals and relay the information to the MCS. The MCS continuously processes this information, determines each satellite's precise location in space and updates the satellites' navigation messages through the ground antennas. The MCS also houses a customer interface: the GPS Warfighter Collaboration Cell is a 24/7 user-focused center supporting a wide variety of military, civilian and commercial users and applications. History The 2nd SOPS originated from the 2nd Surveillance Squadron, Air Defense Command, 9th Aerospace Division, Ent Air Force Base, Colorado. The surveillance squadron, activated Jan. 16, 1962, served as intermediary between various sensor sites and higher headquarters. The squadron was inactivated Jan. 1, 1967, but in May 1985, Air Force Space Command requested the activation of 2nd SS, re-designated as the 2nd Satellite Control Squadron to command and control on-orbit GPS satellites. On Oct. 1, 1985, 2nd SCS was activated at Falcon Air Force Station, Colorado, the first operating squadron of the 2nd Strategic Wing. On Jan. 30, 1992, as part of Air Force reorganization, the 2nd SCS became 2nd SOPS and was reassigned to the 50th Operations Group. On June 18, 2004, the GPS Operations Center, now GPS Warfighter Collaboration Cell, was established. In late 2005, several National Geospatial Agency monitor stations were integrated into the network to improve navigation accuracy and signal monitoring. On July 24, 2020, as part of the U.S. Space Force’s structure change, 2nd SOPS was assigned to Delta 8. With the activation of the provisional Positioning, Navigation and Timing Integrated Mission Delta on Oct 12, 2023, 2nd SOPS was realigned under the PNT Delta. (Current as of April 2024)
