Lockheed Martin completed a “jitter” test of the Space-based Infrared System (SBIRS) High satellite, part of the U.S. military’s next-generation missile warning system, the company said.

The heart of the SBIRS satellite, which will be placed in geostationary orbit, is the ability to use one optical system to rapidly and repeatedly scan an area of interest for infrared activity while not interfering with the second optical system’s ability to simultaneously stare at another area, Lockheed Martin said. The test demonstrated that other sources of movement, such as reaction wheels, solar arrays and various deployable and steerable mechanisms, will not impact the infrared payload.
