Great Circle Navigation

Great circle navigation is a method used in map routing that follows the shortest path between two points on the Earth's surface. Since Earth is round, this shortest path is a segment of a great circle, which is any circle that divides the globe into two equal halves. Traveling along a great circle minimizes distance and fuel consumption, making it ideal for ships and aircraft. Navigators plot these routes using specific calculations to stay on the great circle, ensuring efficient and accurate long-distance travel across the globe.
