The Space Tracking and Surveillance System (STSS; formerly SBIRS-Low) was a pair of satellites developed by the United States Missile Defense Agency (MDA) to research the space-based detection and tracking of ballistic missiles. Data from STSS satellites could allow interceptors to engage incoming missiles earlier in flight than would be possible with other missile detection systems.[4] The STSS program began in 2001, when the "SBIRS Low" program was transferred to MDA from the United States Air Force.[5] In December 2002, SBIRS Low Research & Development (SBIRS Low R&D) was renamed Space Tracking and Surveillance System (STSS).[6]
