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.
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 (1.02 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 the daytime that masks satellites reflected light, dictates that the system operates 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 (30,000 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 objects that is regularly tracked and accounted for. Objects crossing the International Space Station (ISS) orbit within 20 miles (32 km) will cause the ISS to adjust its orbit to avoid a collision. The oldest object tracked is Object #5 (
Vanguard 1
) launched in 1958.
