Missile Defense: Alternate Approaches to Space Tracking and Surveillance System Need to Be Considered.

摘要

The Department of Defense's Missile Defense Agency (MDA) is developing a ballistic missile defense system designed to counter a wide spectrum of ballistic missile threats. A future element of this system is the Space Tracking and Surveillance System (STSS). STSS will eventually be composed of a constellation of satellites that will work together to detect and track missiles throughout all phases of their flight. GAO was asked to analyze MDA's approach to demonstrate capabilities for STSS.
