The Air Force has requirements similar to NASA's for launch environment model V&V and qualification testing. While Air Force spacecraft may not approach the size of some NASA spacecraft, such as the NASA space station for example, Air Force satellites may have instrumentation appendages that cannot be tested in an earth-gravity environment. Potential non-NASA applications stand to benefit from the proposed technology in the same ways as NASA applications. NASA has long been required to ground-test spacecraft and spacecraft components in their launch configuration for model verification, validation and flight qualification because of the severity of the dynamic environment. Ground-testing of spacecraft in their on-orbit configurations is often impractical when not designed to withstand earth-gravity forces. The ability to quantify modeling uncertainty at the substructure level and propagate it to system levels could avoid the need for launch environment model V&V and qualification testing, and enable the assessment of predictive accuracy for on-orbit modeling as well. This technology has potential application to virtually all NASA spacecraft.
