Definitions for "STSS"
Space Tracking and Surveillance System. STSS is a constellation of low-earth orbiting satellites that will detect and provide critical tracking information about ballistic missiles globally. The program is employing a capabilities-based, block upgrade acquisition approach. The first block, termed Block 06 by the Missile Defense Agency (MDA), will be deployed in 2007 to support the missile defense testbed. STSS is designed to support the BMDS which will negate missiles/warheads in boost, mid-course, and terminal phases of flight. STSS will provide tracking through all three phases; discriminate between warheads and decoys; transmit data to other systems that will be used to cue radars and provide intercept handovers; and provide data for intercept hit/kill assessments. STSS provides unique characteristics including global coverage with no foreign basing issues, continual watch on emerging and known threats, and dual phenomenology for discrimination to ensure efficient use of interceptors.
