GPS-less Tunnel Inspection

Underground tunnels are often narrow and it is difficult to conduct human inspection due to poor accessibilities. The best solution is to conduct the inspection by using a drone because they are relatively small in size, and is capable of performing precise inspection of the surroundings. However, lack of GPS signals makes almost every drone unable to fly in tunnel environment autonomously and safely.

AeroLion's expertise in GPS-less navigation had made autonomous tunnel exploration become a reality. With advanced control technologies, 3D real-time localization and mapping capability, AeroLion's drone is able to fly autonomous in tunnel environment, meanwhile collecting the data for documenting & inspection purpose.
