Akshay Tripathi, in the AEDC Space and Missile Test division, install a microsatellite in AEDC’s new Space Threat Assessment Testbed to conduct an initial site acceptance (ISA) test. The initial site acceptance test is the equivalent to the halfway point of mission capability. The STAT can simulate a realistic operational environment to space hardware, using multiple source simulators to emulate the conditions existing at various space orbits. The STAT facility will reach Initial Operating Capability in April, followed by Full Operational Capability certification by September 2013. The facility will be operated under the Space Combined Test Force (CTF). (Photo by Jacqueline Cowan)

STAT is a ground test facility for evaluating the performance of materials, components, subsystems, and small satellites in a test environment capable of providing conditions from low Earth orbit to geosynchronous operations.

STAT simulates natural orbital environment conditions ranging from quiet to various geomagnetic effects generated as a result of solar activity that can impact space assets. Self-induced environmental conditions associated with space systems may also be simulated during testing to investigate potential system-level interactions.

Test chamber conditions and test article observables may be accessible to program sponsors for test article monitoring and control under varying simulated space conditions. Local support is available at Arnold Engineering Development Complex for test planning and execution, and to conduct analysis of test results.

Using the STAT test cell for Research, Development, Test & Evaluation (RDT&E) of materials, components, subsystems, and evolving technologies in a representative space environment can lower development costs and reduce the risk of failure of mission-critical assets. The ability to simulate multiple environmental effects under controlled conditions in a single instrumented chamber provides significant flexibility to support customer requirements. Rapid reconfiguration of test articles and adjustments in test chamber conditions further contribute to a cost-effective test regimen.
