The HereFlow is a miniature UAV navigation board incorporating a time-of-flight LiDAR sensor, an optical flow camera and a six-degree-of-freedom IMU. Weighing just 1 gram, the ultra-low-SWaP board is easy to install into a variety of platforms, and is ideal for aiding UAV precision landing as well as for GNSS-denied navigation in indoor facilities, tunnels and under bridges.

The HereFlow can be conveniently installed at any node in a CAN bus, and multiple units can be installed on a single bus. The sensor's robust design provides protection against signal noise, superior anti-interference capabilities, real-time operations and high-performance error handling.
