The ARK Flow optical flow sensor delivers best-in-class precision navigation and positioning capabilities for unmanned aerial vehicles. Providing highly accurate movement detection by analyzing surface patterns and motion, and also incorporating a time-of-flight distance sensor, it is ideal for ensuring stable flight performance even under GNSS-denied conditions such as inside buildings, tunnels and urban canyons.
The sensor runs PX4 open-source firmware and supports updates over DroneCAN. It also provides support for ROS2.
