Space-based Staring Infrared Sensors
The US, in 1970, launched the first of a series of space-based staring array sensors that detected and located infrared heat signatures. Such signatures, which are associated with measurement of energy and location, are not pictures in the IMINT sense. Currently called the Satellite Early Warning System (SEWS), the program is the descendant of several generations of Defense Support Program (DSP) spacecraft.
Originally intended to detect the intense heat of an ICBM launch, this system proved useful at a theater level in 1990-1991. It detected the launch of Iraqi Scud missiles in time to give early warning to potential targets.
When an arms control agreement, such as the MCTR, limits missile technology transfer, this system can detect missile launches that may have been a result of inappropriate transfer, or independent development by a nation that has not imported rocket motors.

Famous quotes containing the word staring:
“You can forgive people who do not follow you through a philosophical disquisition; but to find your wife laughing when you had tears in your eyes, or staring when you were in a fit of laughter, would go some way towards a dissolution of the marriage.”
—Robert Louis Stevenson (1850–1894)
