Overview
The ULS-OnNet is a compact, Generation 1 precision positioning system designed specifically for small to medium fixed-wing UAVs that land in nets or on tethers. It delivers <5cm horizontal and vertical accuracy at 1m distance (accuracy scales linearly with distance) up to 300 meters in a lightweight, easy-to-integrate package. Purpose-built for net capture and tether hook landing systems, currently in test production with select customers.
