SBIRS High
Space Based Infrared System
Featuring four geosynchronous Earth orbit (GEO) satellites, two highly elliptical Earth orbit (HEO) payloads, and associated ground hardware and software, SBIRS High will provide improved sensor flexibility and sensitivity over the current Defense Support Program (DSP) that it will replace. The sensors will cover short-wave infrared bands like DSP, but will also cover expanded mid-wave infrared and see-to-the-ground bands allowing it to perform a broader set of missions.
SDL fulfilled two roles in supporting SBIRS High. Under contract to Aerojet,
SDL developed, fabricated, and tested infrared sources and transfer radiometers
for the Aerojet Test and Calibration Facility. The facility is being used for
calibration and final acceptance testing on the completed SBIRS High satellites.
SDL also performed spectral tests on the optical filters used in the SBIRS High
infrared sensors. SDL developed the capability to test these filters in an optical
configuration that matches the flight sensor configuration.
