On March 5, 2019, a meeting was held at the headquarters of Spartaqs with representatives of the Kielce University of Technology. We conducted a series of drone acoustic tests in flight. The tests were aimed at determining the maximum range of the listening apparatus, as well as removing the sonic characteristics of the tested drones. The tests were carried out as part of work carried out together with the Kielce University of Technology to improve drone detection techniques as part of the development of the anti-drone shield project. The tests were attended by prof. dr hab. Rafał Chatys- a specialist in composites and dr Marzena Mięsikowska – a specialist in acoustic analysis from the Kielce University of Technology, Mr. Ryszard Królikowski – an expert in the aviation industry and a team of designers from Spartaqs.
