Drone Radio Beacon is a patented solution for driving drones with a very high accuracy (10s of centimeters) and an outstanding reliability. It can be also used as a stand-alone or a redundant safety device in mission critical applications as it does not need any GPS signal or video processing technique to operate. Safe, precise and automated flight is assured by DRB ground station able to drive a compliant drone according to a predetermined path. Drone Radio Beacon can establish no-fly zones, let the drone follow predetermined flight corridors or land it precisely onto the ground station itself. Propretary AI SW runs onboard for features detection in applications such as WTG or powerlines inspections. For example, the actual WTG hub and insulator heights, or the inclination of the wind blade are used in cooperation with the ground station positioning for taking into account the difference between standard waypoints and reality, increasing precision, reliability and safety. The nominal mission is thus updated on the fly keeping full control of the drone flight plan. A suite of tools is also present for enhanced operations that take advantage of DRB autonomous drone system: battery recharging landing station, robotic arm for instruments, sensors for visual, infrared and ultraviolet inspections or NDT. Thanks to DRB AI engine, the DRB platform rapidly analyzes collected data and pictures taken by the drone thus ensuring full value from a drone inspection. In a little time inspection report is produced, divided into categories of priority according to the seriousness of the damage and complete with recommendations to cost-effective improvements.
