The 20th Space Surveillance Squadron (20 SPSS) is a Space Delta 2 unit located at Eglin Air Force Base, Florida with the mission to execute multiplatform, tactical space warfighting domain characterization, recognition, and responsiveness to achieve 21st Space Wing and United States Space Command intent. The unit, formerly designated the 20th Space Control Squadron (20 SPCS), was renamed on 25 March 2022.
Eglin AFB Site C-6's squadron of the 9th Aerospace Defense Division activated in September 1968. and was turned over to Air Force Systems Command on 20 September 1968, and became operational in December 1968.
Eglin Site C-6 was assigned to Aerospace Defense Command on 20 December 1968. In 1972 20% of the site's "surveillance capability…became dedicated to search for SLBMs" and was subsequently renamed the 20th Missile Warning Squadron (the USAF SLBM Phased Array Radar System was initiated in November 1972 by the JCS while the Army's MSR and PAR phased arrays for missile defense were under construction.) The AN/FPS-85 facility was expanded in 1974, [1] and "a scanning program to detect" SLBM warheads was installed in 1975. [2] Alaska's AN/FPS-108 Cobra Dane phased array site was completed in 1976 and from 1979 until 1983, Site C-6 was assigned to Strategic Air Command's Directorate of Space and Missile Warning Systems (SAC/SX)--as were the new PAVE PAWS phased array sites operational in 1980.
On 25 March 2022, the squadron was renamed the 20th Space Surveillance Squadron (20 SPSS) in a ceremony officiated by the Space Delta 2 Commander, Colonel Mark Brock.
In 1983 Eglin Site C-6 transferred to Space Command (later renamed Air Force Space Command), and the "FPS-85 assumed a deep space role in November 1988 after receiving a range-extension upgrade enabling integration of many pulses." With the addition of additional missile warning sites becoming active, the squadron eliminated its missile warning mission, and the surveillance squadron name was restored in 1987. The unit was renamed the 20th Space surveillance squadron when a "new radar control computer" was installed at the site in 1994. By 1998, the site was providing space surveillance on "38 percent of the near-earth catalogue" of space objects (ESC's "SND C2 SPO was the System Program Office.) "A complete modernization…of the 1960s signal-processing system was being studied in 1999", and in 2002 Site C-6 was tracking "over 95 percent of all earth satellites daily."[ citation needed ] The squadron was renamed the 20th Space Control Squadron in February 2003. In 2004, significant components of Naval Space Command were transferred to the 20th Space Control Squadron, including components of the former Naval Space Surveillance System (renamed the Air Force Space Surveillance System). [3] By 2011 the site's "16 million observations of satellites per year" (rate of 30.4/minute) was "30 percent of the space surveillance network's total workload".[ citation needed ]
In September 2020, the 20 SPCS joined the newly created United States Space Force. [4]
In 2016, the 20th Space Control Squadron acquired the three Ground-based Electro-Optical Deep Space Surveillance (GEODSS) sites. GEODSS is an optical system that uses telescopes, low-light level TV cameras, and computers. It replaced an older system of six 20 inch (half meter) Baker-Nunn cameras which used photographic film.
There are three operational GEODSS sites that fall under the 20th Space Control Squadron:
GEODSS tracks objects in deep space, or from about 3,000 mi (4,800 km) out to beyond geosynchronous altitudes. GEODSS requires nighttime and clear weather tracking because of the inherent limitations of an optical system. Each site has three telescopes. The telescopes have a 40-inch (1.0 m) aperture and a two-degree field of view. The telescopes are able to "see" objects 10,000 times dimmer than the human eye can detect. This sensitivity, and sky background during daytime that masks satellites reflected light, dictates that the system operate at night. As with any ground-based optical system, cloud cover and local weather conditions directly influence its effectiveness. GEODSS system can track objects as small as a basketball more than 20,000 miles (32,000 km) in space or a chair at 35,000 miles (56,000 km), and is a vital part of Space Command's Space Surveillance Network. Each GEODSS site tracks approximately 3,000 objects per night out of 9,900 object that are regularly tracked and accounted for. Objects crossing the International Space Station (ISS) orbit within 20 miles (32 km) will cause the ISS to adjust their orbit to avoid collision. The oldest object tracked is Object #5 (Vanguard 1) launched in 1958. [5]
PAVE PAWS is a complex Cold War early warning radar and computer system developed in 1980 to "detect and characterize a sea-launched ballistic missile attack against the United States". The first solid-state phased array deployed used a pair of Raytheon AN/FPS-115 phased array radar sets at each site to cover an azimuth angle of 240 degrees. Two sites were deployed in 1980 at the periphery of the contiguous United States, then two more in 1987–95 as part of the United States Space Surveillance Network. One system was sold to Taiwan and is still in service.

Eglin AFB Site C-6 is a United States Space Force radar station which houses the AN/FPS-85 phased array radar, associated computer processing system(s), and radar control equipment. Commencing operations in 1969, the AN/FPS-85 was the first large phased array radar. The entire radar/computer system is located at a receiver/transmitter building and is supported by the site's power plant, fire station, 2 water wells, and other infrastructure for the system. As part of the US Space Force's Space Surveillance Network its mission is to detect and track spacecraft and other manmade objects in Earth orbit for the Combined Space Operations Center satellite catalogue. With a peak radiated power of 32 megawatts the Space Force claims it is the most powerful radar in the world, and can track a basketball-sized object up to 22,000 nautical miles (41,000 km) from Earth.
