Geo-2 sbirs acoustics tested.

The second US Air Force Space-Based Infrared System (Sbirs) satellite (Geo-2) built by Lockheed Martin has successfully completed acoustic testing that simulates the maximum sound and vibration experienced during satellite launch. The next series of tests will include thermal vacuum qualifications, which exposes the Sbirs birds to temperatures higher than those expected during its operational lifetime. The Sbirs satellites were designed to give advanced missile warning to the US military, and to support critical missile defence applications, provide technical intelligence and enhance battlespace awareness - essentially, to operate as space-based C4ISR assets. The first geosynchronous satellite (Geo-1) was launched on 7 May 2011 and has deployed its instruments and activated its infrared sensors. Geo-2 will be launched in spring 2012. Northrop Grum-man is payload integrator under the Sbirs contract, which includes the two satellites. A follow-on contract to deliver additional payloads and the third and forth Geo satellites has been signed.
