BVLOS

Beyond Visual Line of Sight (BVLOS) is a drone operation mode in which an unmanned aerial vehicle (UAV) flies beyond the distance where the remote pilot can maintain direct visual contact. Unlike Visual Line of Sight (VLOS) operations, which require the drone to remain visible throughout the flight, BVLOS enables drones to travel longer distances and access remote or hard-to-reach areas. Safe BVLOS flights rely on advanced technologies, including long-range communication networks, satellite navigation (GNSS/GPS), real-time telemetry, onboard sensors, detect-and-avoid systems, and autonomous flight control software. These systems continuously transmit flight data, allowing operators to monitor the drone's location, altitude, speed, battery status, and surrounding environment from a ground control station. BVLOS operations improve efficiency, reduce operational costs, and expand the capabilities of drones across industries. They are widely used for infrastructure inspection, precision agriculture, power line and pipeline monitoring, logistics and delivery, disaster response, environmental monitoring, mapping, surveying, and public safety, making them a key advancement in modern drone technology.
