#^Researchers Develop Advanced Silicon Photonic Chip for GPS-Free NavigationLos Angeles CA (SPX) Aug 14, 2024

Inside devices like smartphones, fitness trackers, and virtual reality headsets, small motion sensors track movement. Larger, more sophisticated versions of these sensors, about the size of a grapefruit and significantly more accurate, are used to help navigate ships, airplanes, and other vehicles with GPS assistance. Scientists are now working to create a motion sensor so precise that it
