Altitude Testing

The unique challenges of using tactical sensors on airborne systems, including UAVs, requires specialized systems to test under high-altitude temperature and pressure conditions. SDL operates and maintains a state-of-the-art altitude test chamber on behalf of the Missile Defense Agency (MDA) for high-fidelity and realistic operation simulation.
