A flight tested Right-of-Way (RoW) compliant algorithm has been developed as part of ongoing research efforts in the development of Airborne Sense and Avoid (ABSAA) technologies by the University of North Dakota Unmanned Aircraft Systems Engineering (UASE) team. This paper presents the results of development, implementation, and flight testing of a RoW algorithm during the summer of 2011 in a restricted airspace using a combination of varying intercept angles for the cases of a single intruder and dual intruders. These tests yielded positive results demonstrating the RoW compliance to enhance the UASE ABSAA system that was developed under a series of projects funded by the Department of Defense (DoD). The work presented implements the future NextGen National Airspace System (NAS) technologies and has the ability to incorporate multiple sensor streams into the decision space. An integral part of the NextGen NAS is the FAA’s final rule regarding “Automatic Dependent Surveillance-Broadcast (ADS-B) Out Performance Requirements to Support Air Traffic Control (ATC) Service,” which will propel forward the transition from a radar based system to a satellite driven system. This mandated technology allows for the development of a robust ABSAA system for Unmanned Aircraft Systems (UAS).
