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
