New Approach Redefines Navigation In GPS-Denied Environments

As drones become increasingly used in logistics, reconnaissance, and combat missions, the need for reliable navigation in GPS-denied environments is growing. A new approach, 3D vision-based navigation, is gaining traction, combining onboard cameras with high-resolution map data to enable accurate positioning. Vantor’s Raptor solution is at the forefront of this technology, providing a 3D reference layer for real-time positioning. According to Breaking Defense, this technology is critical for UAS operations, where drones often fly closer to the ground than traditional crewed aircraft.
