Canadian UAVs, as part of the LOOK North Detect and Avoid (DAA) trials, has effectively demonstrated the Sparrowhawk Radar as a qualified solution for enabling beyond visual line of sight (BVLOS) Remotely Piloted Aircraft System (RPAS) operations in Canada. Under observation from Transport Canada and the National Research Council, Canadian UAVs held trials at the Foremost UAS Test Range to validate the function of their Sparrowhawk Radar – a low-cost solution for DAA.
Sparrowhawk is much more than a ground-based radar system. It is a comprehensive technology solution which combines low-cost radars of various forms with computer vision, predictive modelling, data presentation and RPA flight contingency planning. The raw data received from the radar is distilled into an airspace picture and presented to the RPAS operator natively on the ground control station. Air risk is then automatically interpreted during airspace intrusions, allowing for emergency procedures engagement by the operator, or automatic evasive maneuvers.
“It is overly simplistic to think you can just buy a radar and start flying BVLOS. We have spent four years selecting and developing the technology, processes, and safety protocols to determine and interpret the fingerprint of an airspace” said John Molberg, Vice President of Innovation at Canadian UAVs. “We take a holistic view of the entire problem before we start flying BVLOS. This approach takes into account the needs of the company, the customer, the regulator, and of course, other airspace users. We have been working with Transport Canada for years to demonstrate that economic and effective DAA is possible for RPAS operators. Our partnerships have allowed for this innovation to develop organically in Canada.”
Sparrowhawk is a Canadian innovation made possible through an assortment of public and private investments in Canadian UAVs Inc. Investment has been leveraged from NSERC, IRAP, Tecterra, LOOKNorth, and most significantly as part of the SkySensus Project, a research and development project under Industrial and Technological Benefits (ITB) funded and led by Peraton Canada. These investments facilitate Canadian UAVs’s mission of providing the ecosystem for integration of UAVs into complex airspace by helping to ‘crack’ the most difficult problem facing the widespread adoption of RPAS in Canadian skies: Detection and Avoidance of manned aircraft.
“Peraton’s SkySensus ITB investment is an example of public policy made good” says Chris Brosinsky, Chief Operating Officer at UxS Consulting, and former director of the IDEaS program at the Department of National Defence. “By combining industry demand with ITB funding, this policy is helping Canadian innovators address significant barriers in the emerging RPAS industry.”
The DAA trials, sponsored in part by LOOKNorth, set in motion a series of technology demonstrations to measure the efficacy of different forms of DAA. Canadian UAVs, as part of this demonstration, showcased the effectiveness of its ground–based radar and software by commissioning a manned RV-10 aircraft to fly at the Foremost UAS Test Range. Canadian UAVs engineers and operators tested detection of the aircraft from 2 NM to 8 NM (15 km) in real-time. The aircraft altitude varied from 400 to 4000 feet AGL with typical and atypical flight paths flown to thoroughly test detection performance. On-board the aircraft was a GPS/IMU tracker supplied by the National Research Council (NRC) to establish the ground truth reference for detection analysis. Sparrowhawk’s performance was assessed against the aircraft’s GPS data to confirm the accuracy and reliability of detections.
