DRB

DRB (Drone Radio Beacon) is an Italian autonomous drone inspection company that develops GPS-free drone systems for the inspection of critical infrastructure assets. Founded as a Politecnico di Milano spinoff, DRB's patented technology uses ground station-based radio positioning to enable drones to fly with centimeter-level accuracy in environments where GPS signals are unavailable or unreliable. Their integrated hardware and software suite includes the Drone Radio Beacon Ground Station, onboard AI for feature and damage detection, multi-spectrum sensors, robotic arms, and battery recharging stations. The DRB Web Platform processes inspection data and generates automated reports ranked by damage severity. DRB serves customers in renewable energy (wind turbines, solar and hydro farms), electrical transmission and distribution infrastructure, oil and gas refineries, offshore platforms, bridges, and dams. The company also targets logistics for package delivery and indoor industrial automation. DRB partners with major Italian utilities including Terna SpA, providing operators with safer, faster, and more repeatable inspection workflows than traditional manual methods.
