Скачать или смотреть UAV Avoidance System for Crowded Airspace

In a world where drones perform a multitude of tasks, it is not unforeseeable that several UAV companies will use the same airspace at the same time. While one company can keep meticulous safety margins for its own UAV fleet, it does not necessarily know where other UAVs may be operating. To avoid mid-air collisions, Wing Aviation has patented adding a sensor to their UAVs to receive ADS-B signals.

According to Wikipedia, “Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it to be tracked.” This means that the UAVs can see other aircraft that are also equipped with ADS-B.

As the patent states, “Often, a fleet of UAVs is controlled by a central system that provides planned route information to UAVs which then autonomously navigate the planned routes. While the central system can attempt to ensure that none of the planned routes will conflict with each other (i.e., no UAV traversing a planned route will come within a safety margin of another UAV), the central system may not have information about other aircraft that are not part of the fleet of UAVs that may be present in an operating region for the fleet of UAVs, including but not limited to general aviation aircraft.”

If an ‘intruder’ aircraft is detected the UAV’s onboard computer can either alter the flight path or ground the drone as long as there is a safe spot to land.
