OVERVIEW: A satellite-based IR (Infrared) camera is a spaceborne imaging sensor designed to detect and record thermal radiation emitted by objects on Earth or in space. These cameras enable continuous, high-altitude thermal surveillance for military, environmental, meteorological, and strategic intelligence purposes.

GENERAL DESCRIPTION: Introduced in the late 1980s to early 1990s, second-generation geosynchronous satellite infrared (IR) cameras were designed to detect and track ballistic missile launches by capturing thermal emissions during the boost phase. These systems featured improved focal plane arrays, often cooled for better sensitivity, and operated in dual MWIR and LWIR bands. Their advanced optics and faster scanning allowed higher accuracy in threat classification and trajectory estimation, forming the backbone of upgraded early warning constellations.

ROLE SUMMARY:
Category: Infrared Surveillance / Strategic Early Warning
Primary Use: Missile launch detection and tracking
Function: Passive thermal monitoring
Platform: Geostationary satellites
