The Ukrainian NORDA Dynamics presented an optical navigation system for UAVs. The updated automatic optical guidance system is capable of fixing and tracking moving targets at a distance of up to 2 kilometers in favorable weather conditions. The convolutional neural network model for the AI version of Underdog is trained to select nine distinct classes of targets. The presented navigation add-on provides route definition without the involvement of satellite systems thanks to the combination of optical terrain matching algorithms with terrain maps and visual-inertial distance checking. The module also supports integration with terrestrial radio beacons from sine and skyline engineering developers. The device is designed both as a separate unit and for work as part of the company's general line. More details - in the link.
