ÐÓ°ÉÊÓƵ’s Space Environmental Test Facility in El Segundo, California, features a variety of capabilities specifically designed to test products against the harsh conditions of space. With decades of experience building and testing satellites, our labs can be used to simulate dynamic launch and space environmental conditions, including extreme cold, solar and electromagnetic radiation, vibration, and vacuum. Some key test capabilities are highlighted below.

• Our large (68,000 cubic-feet/20,726.4 cubic meters) acoustic test chamber can accommodate very large test articles and is able to test against vibration within a realistic gaseous simulated atmosphere. The lab is equipped with two 20-hertz and two 50-hertz WAS 3000 horns and four 200-hertz EPT 200 horns and is completely insulated and isolated from external interferences. The chamber performs at an overall sound pressure level (OASPL) of 155 decibels.
• Our 45-by-35-by-40-foot (13.7-by-10.7-by-12.2-meter) thermal vacuum chamber is able to simulate the extreme environment of space in both vacuum and cold with a shroud temperature liquid nitrogen capability of minus 320 degrees Fahrenheit (minus 195 degress Celsius) and a gaseous nitrogen range from minus 250 F (minus 157 C) to 250 F (121 C). It can be configured to simulate ambient solar radiation and is large enough to accommodate a variety of test article dimensions, even multiple test articles at once.
• Our large anechoic chamber (31.6 by 39.3 feet/9.6 by 12 meters and 26.5 feet/8 meters high) provides the ability to conduct antenna radiation patterns, electronic magnetic interference and compatibility (EMI/EMC), and payload testing via air linking the radio frequency (RF) signal to and from a satellite. The chamber is highly flexible accommodating various types of power supply sources with multiple power connections.

The ÐÓ°ÉÊÓƵ Noise Engineering Laboratory has an expert staff and state-of-the-art equipment ready to help you isolate and measure noise and its effects. Our dedicated noise facilities and sophisticated information-handling systems make our laboratory one of the best in the world.

The Interior Noise Test Facility features an anechoic and a reverberant chamber, and it tests and measures noise from environmental control systems and hydraulic systems.

The Materials Test Center accommodates structural acoustics testing on a variety of components and assemblies. It houses a flow bench and impedance tubes to test acoustical resistance and impedance and Rayls.

The Quiet Air Facility is a versatile, general-purpose hemianechoic chamber with two muffled air supplies and controls for developing and testing the design of environmental control systems and components, calibrating instruments, and developing and verifying small- to medium-size mechanical and electrical components and systems.
