UAS - Successful Navy Funded, ADS-B based Autonomous, Sense and Avoid - With Pilot Overide Demonstrated

Two Navy Tiger Shark UAS, with Piccolo autopilots, and AWSAS R3's All Weather Sense and Avoid System, successfully conducted autonomous avoidance maneuvers over five days. The tests also demonstrate AWSAS as "middle ware" using different airframes, autopilots and different Sense and Avoid Software from previous flights. In August of last year, the AWSAS (ABSAA) system executed the first ADS-B fully autonomous collision avoidance test at the US Navy Long Range Base in Argentia, Newfoundland.

LEXINGTON PARK, Md. - April 26, 2013 - PRLog -- R³ Engineering LLC (R³E) announces successful demonstration of autonomous collision avoidance during flight tests that took place the week of April 15th-19th at Yuma Proving Ground (YPG) in Arizona.

Two Tiger Shark UAS, equipped with Piccolo autopilots and AWSAS (R³E’s All Weather Sense and Avoid System), successfully conducted autonomous collision avoidance maneuvers over the 5 day period. The current series of flight tests demonstrates the AWSAS’ “middle ware” functionality with different airframes, different autopilots and different Sense and Avoid (SAA) software from previous flight tests. Flight scenarios executed at YPG were designed to trigger AWSAS’ collision avoidance algorithm that generated an autonomous maneuver to clear the conflict. Tiger Shark UAV pilots, operating from a ground station nearby, also demonstrated their ability to override the autonomous maneuver, an important capability of the airborne system.

In August of last year, the AWSAS Airborne Sense and Avoid System (ABSAA), executed the first known ADS-B based, fully autonomous collision avoidance event during flight tests at the former US Navy Long Range Patrol Base at Argentia, Newfoundland. The YPG flights are part of an increasingly challenging series of tests focused on the eventual integration of unmanned aircraft systems (UASs) into the National Airspace System (NAS). Future flight testing, planned for this summer, will incorporate non-cooperative target data from other sensor systems (radar, EO/IR, etc.).

About R³ Engineering LLC
R³ Engineering, LLC, was founded in 2009 and is based in Lusby, Maryland. Its principals are engineers with considerable experience in Naval aviation, including system safety. The AWSAS, R³E’s first product, was developed for the purpose of enabling unmanned aircraft to safely operate in cooperative airspace; and when augmented by appropriate non-cooperative sensors, to operate safely in any airspace. R³E’s open architecture design accepts SAA software from any source; and can function on any platform, with any autopilot or any ground display.
