Conclusion and Next Steps • NASA’s UAS Integration into the NAS project has developed an LVC architecture to support testing of unmanned Detect and Avoid research • LVC Distributed Test Environment was built up from legacy infrastructure and designed to meet DAA test objectives and requirements • Integrating with NASA’s SMART -NAS Test Bed will enable continued use of the LVC technologies 10
