Aeronautical Systems, Inc. (GA‑ASI) completed the first operational testing of a Detect and Avoid (DAA) system on board the company’s B Remotely Piloted Aircraft (RPA). The DAA system being tested included a Due Regard Radar ( ) developed by the company, ’s Traffic Alert and Collision Avoidance System (TCAS) and Sensor Tracker, specifically designed for DAA. The system was flown on a U.S. Customs and Border Protection ( ) , a maritime variant of ’s B RPA.
“The successful completion of our anti-collision radar system operational testing byis a huge milestone for our DAA system as it represents the first integration and evaluation of on an operational UAS,” said David R. Alexander, president, Aircraft Systems, . “CBP’s follow-on operational use of the DAA system in domestic and international airspace will further validate the work being done by the FAA and NASA to introduce RPA into the National Airspace System.”
Conducted in cooperation with CBP the tests demonstrated’s functionality in the national and international airspace operational environment. DAA scenarios included ‘intruder’ aircraft such as a Cessna C-210 and UH-60 Black Hawk equipped with a mix of Mode A/C Transponders, TCAS, and Automatic Dependent Surveillance-Broadcast (ADS-B) transponder capabilities flying close to .
During each encounter, onboard sensor data was combined and downlinked to the pilot’s traffic display with DAA-specific alerts and guidance, ensuring safe separation between Guardian and the intruder aircraft. The initial overland testing began at GA-ASI’s Gray Butte Flight Operations facility near Palmdale, Calif., on March 10 and concluded April 25 over the eastern Pacific Ocean. The tests confirmed that the DAA system provided the RPA pilot with a clear picture of surrounding air traffic, at least as good as ‘eyes in the cockpit’ of a manned aircraft. They also proved the DAA system’s ability to be operated in concert with other radar payloads on the same aircraft, such as Guardian’s SeaVue maritime surface search radar.
CBP operates nineB and Guardian aircraft and is the first customer to employ GA-ASI’s DAA/DRR system in an operational environment. The successful operational testing of DRR aboard Guardian coincides with continued Predator B flight demonstrations conducted in partnership with the FAA, NASA, and industry partners. This work is helping to define airspace regulations that will allow further integration of RPA/UAS into civilian airspace.
The Guardian was modified from a standard Predator B with structural, avionics, and communications enhancements, as well as the addition of aSeaVue Marine Search Radar and an Electro -optical/ infrared sensor that is optimized for maritime operations. OAM pilots use the Guardian to conduct long -range surveillance in support of joint counter – narcotics operations in the southeast coastal and Gulf of Mexico border regions and drug source and transit zones, where maritime radar is necessary to detect a variety of threats. Video recorders document suspect activities for evidentiary use.
According to CBP Office of Air and Marine (OAM) operations, six Guardians are assigned to the Southwest Border Region, two are assigned to the Northern Border and two s UAS are assigned to Cape Canaveral Air Force Station in Florida.
