Description: The Space Tracking and Surveillance System (STSS), formerly known as SBIRS-low, will be a low-Earth orbiting network of satellites. STSS satellites will host multi-spectral sensors designed to observe, accurately characterize and report on ballistic missiles on all phases of their flight. From their low-Earth orbit vantage point, STSS satellites will have the unique ability to observe the boost phase, the midcourse flight of ballistic missiles, including post-boost vehicle maneuvers, reentry vehicles deployments and the use of penetration aids and other countermeasures.

The STSS constellation will replace current DSP satellites beginning in the year 2006/07 providing missile warning and technical intelligence gathering. It will provide critical information for planned ABM defenses, currently the GMDS (Ground based Mid-course Defense Segment) and Theater (battlefield) defenses.

The STSS constellation would consist of 20/30 satellites with the ground control center installed in Buckley Air Force Base facilities, Colorado, a secondary ground control center would be placed in the Schriever Air Force Base, Colorado. STSS would achieve IOC (Initial Operational Capability) in the 2006/07 timeframe with the first satellite launch. Early plans called for the first launch in 2006 achieving IOC in 2010.
