The UAV Collaborative offers a wide range of services to support further research, development, and commercial implementation of UAV technologies. Below are some of the major services provided: National Airspace authorization | Flight safety Assurance | Payload/platform selection and integration Image processing | Platform and payload operations | Education and training UAV operations in the US National Airspace System (NAS) currently require FAA Certificates of Authorization. The certification process requires a mechanism whereby the UAV pilot will be able to reliably sense and avoid other air traffic in the operations area. The industry is making significant progress on several support technologies, including GPS navigation, Automatic Dependent Surveillance - Broadcast (ADSB), Traffic Alert and Collision Avoidance System (TCAS), Mode S secondary surveillance radar (SSR), and Identify Friend/Foe (IFF) transponder. While these technologies are designed to provide information on conflicting aircraft to the ground-based UAV pilot, the requirement to see and avoid other manned aircraft flying under visual flight rules (including non-cooperative aircraft operating without a transponder) continues to be a major limiting factor for UAV flight operations. The UAV Collaborative has conducted tests of the capability ground-based radar for the detection of non-cooperative aircraft. The functionality of ground-based radar for UAV flight safety would involve providing UAV pilots with the necessary situational awareness of the air traffic environment. In this way, UAV pilots could maintain the safe separation distances needed to ensure that the UAV's flight path does not conflict with the flight path of a manned aircraft. The safe operation of UAVs operating beyond the visual range of UAV pilots is a fundamental flight safety requirement for advances in UAV technology.
