At the end of August, BOREAL SAS carried out several flights of its drones equipped with different payloads such as an inertial unit from the company IXBLUE or a hyper-spectral camera. The data collected on the ONERA site in Esperce will be used for multiple ongoing projects and in particular the one called FRELON (FREnch LONg range lidar) intended to design a new generation lidar that is more efficient over long distances.
