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.
