GPS-Denied Navigation Techniques

GPS-denied navigation techniques allow vehicles and devices to determine their position without relying on GPS signals. These methods use alternative sensors and systems such as inertial measurement units (accelerometers and gyroscopes) to track movement, visual cues like cameras to recognize landmarks, LiDAR sensors to map surroundings, and radio signals like Wi-Fi or radio beacons. By combining data from these sources with advanced algorithms, the system can estimate its location accurately even when GPS signals are unavailable or jammed. This approach enhances reliability and safety for autonomous vehicles, UAS, and other navigation-dependent technologies in challenging environments.
