[Satellite TODAY 03-21-13] The U.S. Air Force launched the GEO-2 satellite March 19, the second of its second next-generation missile warning constellation.
The GEO-2 was launched via a United Launch Alliance Atlas 5 rocket into geosynchronous orbit in the Space Based Infrared System (SBIRS). This system aims to include four satellites in geosynchronous orbit, infrared sensors hosted on classified satellites in highly elliptical orbits and ground stations to receive, process and distribute the data. SBIRS will replace the Defense Support Program constellation that has been in operation since the early 1970s. Lockheed Martin Space Systems serves as the prime contractor for the project and Northrop Grumman is the payload manufacturer.
"Today’s successful launch of the GEO-2 satellite marks another milestone in the evolution of infrared surveillance from space," Northrop Grumman Military and Civil Space business area Vice President Stephen Toner said in a statement. "The team played a significant role ensuring that the sensors on GEO-1 are performing beyond specification, and we are confident that the GEO-2 sensors will exhibit similar performance."
