The ARK Flow MR is an NDAA-compliant drop-in upgrade module for the ARK Flow optical flow and distance sensor module, providing enhanced navigation and positioning capabilities for unmanned aerial vehicles and ensuring stable flight performance even under GNSS-denied conditions such as inside buildings, tunnels and urban canyons.
The miniature module features an upgraded optical flow module and time-of-flight distance sensor, and extends the distance sensing range of the ARK Flow up to 50 meters while adding just 5 grams to the system weight.
The sensor runs PX4 open-source firmware and supports updates over DroneCAN. It also provides support for ROS2.
