USA-230, also known asSBIRS GEO-1,[1] is aUnited Statesmilitary satellite and part of theSpace-Based Infrared System.
In the mid 1950s, the United States began development of the first space-based missile detection system; theMissile Defense Alarm System (MIDAS), inlow Earth orbit. Following the end of the MIDAS programme, plans to deploy an operational system led to the Integrated Missile Early Warning Satellite programme (IMEWS), followed by the Defense Support Program (DSP),
The SBIRS satellites are a replacement for theDefense Support Program early warning system. They are intended to detectballistic missile launches, as well as various other events in theinfrared spectrum, includingnuclear explosions,aircraft flights, space objectentries and reentries,wildfires andspacecraft launches.
SBIRS-GEO 1 was manufactured byLockheed Martin Space and is built upon theA2100Msatellite bus.
SBIRS GEO-1 was launched on 7 May 2011 fromCape Canaveral (CCAFS), atop anAtlas V 401 (AV-022)launch vehicle.[2][3]
