Abstract	Flight test of a sense and avoid (SAA) system for Unmanned Aerial Systems (UAS) was recently conducted. The SAAFT program addressed these challenges with an SAA system that autonomously detected and autonomously avoided potential collisions with both cooperating and non-cooperating intruders. AFRL/VACC is the technology customer; Northrop Grumman is the prime contractor; DRA (EO sensor system), Calspan (flight test), Bihrle (algorithms), and C2Projex (situational awareness) were subcontractors, and the FAA Tech Center is a partner and provided the intruder aircraft. Sensors employed were electro-optical (EO), long wave infrared (LWIR), Traffic Alert and Collision Avoidance System (TCAS), and Automatic Dependent Surveillance Broadcast (ADS-B). Flight testing was conducted on Calspan’s Learjet in-flight simulator from Calspan’s facility in Niagara Falls, NY in the Misty MOA over Lake Ontario. Calspan’s Learjet simulated dynamics of a high altitude long endurance (HALE) aircraft. The FAA provided a King Air representing a general aviation intruder, a Convair representing a commuter transport intruder, and TSPI and ADS-B equipment. Three rounds of flight test were conducted between October 2006 and January 2007. The Learjet was flown in various near-collision encounter scenarios with the intruder aircraft. This presentation describes the component technologies which comprise the SAA system, the accomplishments achieved and lessons learned from the flight test activities.
