Without GPS, GLONASS and external communication: in Russia, the SOVA autonomous navigation system was successfully tested. The VA Technologies development helps the UAV determine its position by matching the image from the camera with a previous satellite map. During the tests, the UAV lost its course on the changing surface, but the forest belt re-aligned and adjusted the course. How "SOVA" works, what accuracy the developers claim and what can prevent it - see in the card. #cards360 subscribe to us at MAX I Feedback.
