D20 is a heavy-duty multirotor UAV, equipped with a high-efficiency UAV system for intelligent aerial survey, remote sensing, and inspection.
D20 also adopts millimeter-wave radar, which can realize high-precision terrain awareness flight with direct distance measurement and altitude determination, further reduces the dependence on the accuracy of 3D geographic base map and network conditions, and then realizes automatic line inspection, obstacle avoidance and altitude determination.
It also uses dual differential antennas to ensure safer flight and better anti-interference ability under complex conditions. It can take off, land and fly in mining areas, bridges and surface ships.
