As drones scale across logistics, reconnaissance, and combat missions, adversaries are prioritizing ways to deny or spoof the Global Positioning System (GPS). From nation-states to rogue actors — and even hobbyists — the tools to disrupt GPS are becoming cheaper, more accessible, and easier to deploy.
Without GPS, drones can lose the ability to navigate accurately or stay on course, increasing the risk of mission failure, interception, or loss. To mitigate this, a new approach is gaining traction: 3D vision-based navigation. By combining onboard cameras with high-resolution map data, drones can continuously verify their position and maintain their route — even in GPS-denied environments.
At the core of this approach is accurate, up-to-date 3D terrain data. Precise…
