USA-336 is a three-axis stabilized satellite equipped with an Overhead Persistent Infrared (OPIR) scanner. [5] USA-336 uses its OPIR scanner and long-range surveillance to provide early warning for Ballistic Missile launches. [1] [4] It will replace older Defense Support Program satellites. [5]
The SBIRS satellites are a replacement for the Defense Support Program (DSP) early warning system. They are intended to detect ballistic missile launches, as well as various other events in the infrared spectrum, including nuclear explosions , aircraft flights, space object entries and reentries, wildfires , and spacecraft launches .
It complemented the geosynchronous Defense Support Program, the Space-Based Infrared System, and other overhead non-imaging infrared (ONIR) systems [15] [16] and provided tracking cues to systems on the surface. The STSS program was developed in phases, the first of which was the launch of two demonstrator satellites.
Based on its experiences with the launching of short-range theater missiles by Iraq during the 1991 Persian Gulf War, the U.S. Department of Defense (DoD) concluded that expanded theater missile warning capabilities were needed, and it began planning for an improved infrared satellite sensor capability that would support both long-range strategic and short-range theater ballistic missile ...

As opposed to an ordinary forward looking infrared system, an IRST system will actually scan the space around the aircraft similarly to the way in which mechanically (or even electronically) steered radars work. The exception to the scanning technique is the F-35's DAS, which stares in all directions simultaneously, and automatically detects ...
ORS-2. Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit.A number of Earth-observing satellites, such as RADARSAT, have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth.
Next-Generation Overhead Persistent Infrared (Next-Gen OPIR) is being developed in USA as the replacement for the current missile warning constellation, the Space-Based Infrared System (SBIRS). [ 1 ] The Next-Gen OPIR satellites are engineered to detect and track ballistic missile launches, delivering early warnings of potential attacks.
