BVLOS
BVLOS (Beyond Visual Line of Sight)
Means operating a drone out of the pilot's direct naked-eye view. Instead of relying on sight, the pilot guides the drone using a ground control station, relying on real-time camera feeds, GPS telemetry, and onboard sensor data. This allows drones to fly miles away from the operator.
BVLOS require the operator to physically see the aircraft at all times, limiting flights to a few hundred meters. BVLOS breaks this barrier, unlocking highly scalable, long-distance applications:
- Infrastructure Inspection: Monitoring miles of power lines, oil pipelines, or railways without physically relocating the pilot.
- Package Delivery: Transporting medical supplies or commercial goods across large geographic areas or cities.
- Agriculture & Surveying: Mapping massive farmlands or tracking topographical changes over large distances.
How it Works
To fly safely without direct human oversight, BVLOS drones rely on advanced, interconnected technologies:
- Robust Command & Control (C2) Links: Stable, long-range communication systems using 4G/5G networks, satellite, or dedicated radio frequencies to send instructions and receive feedback.
- Detect-and-Avoid (DAA) Systems: Onboard sensors, radar, and cameras that automatically identify and steer clear of other aircraft or obstacles
- Redundant Navigation: Advanced GPS and navigation suites ensuring the drone stays on course even if one positioning system malfunctions.
- Onboard AI & Telemetry: Built-in intelligence that manages automated flight paths and reports real-time data back to the base. Because of the increased safety risks, BVLOS flights are highly regulated. In regions like the United States (governed by the FAA) or under global agencies, operators usually need special waivers or specific operational authorizations to conduct these flights.
