Global Positioning System (GPS) [2, 5]. Though the physical line at the Royal Observatory in Greenwich is a popular tourist spot, modern satellite technology has actually shifted the "true" geodetic meridian about 102 meters east of the original Victorian line [5]. Every time you look at a GPS map, you are using the legacy of 18th-century sailors and the 1884 conference that finally gave the world a common center. Would you like to know more about how
Meridian longitude is more than a line on a map—it is the foundation of global navigation, timekeeping, and our shared understanding of location. From ancient astronomers to modern GPS, the quest to measure how far east or west we are has driven innovation and connected the world. The next time you look at a map, remember that every vertical line tells a story of geometry, history, and human ingenuity. meridian longitude
