Raytheon Space and Airborne Systems of El Segundo, Calif., demonstrated March 7 a fully integrated infrared sensor the company built under a risk reduction contract for the Alternative Infrared Satellite System (AIRSS) program. The AIRSS program was originally conceived as a stop-gap missile warning option that was being developed concurrently with the Space-Based Infrared System. AIRSS has now been redesignated as a follow-on system and renamed the Third Generation Infrared Surveillance System. Raytheon began work on the sensor in September 2006 after being awarded a 18-month, $54 million contract from the U.S. Air Force. The sensor will now undergo environmental testing, according to a March 13 Raytheon press release.
