The Missile Defense Agency s Precision Tracking Space System PTSS is intended to be a satellite system equipped with infrared sensors that track ballistic missiles through their emitted heat. The planned satellite system includes a constellation of nine satellites in orbit at the same time around the earth s equator. In April 2013, the Department of Defense DOD officially proposed canceling the PTSS program because of concerns with the program s high-risk acquisition strategy and long-term affordability.
