Which professions need to use great circles to perform their duties?

Great circles are the shortest paths between two points on a sphere, like Earth. They're essential in professions that deal with long-distance travel or global planning. Pilots and ship captains use them to chart efficient routes. Satellite engineers rely on them for orbital paths. Mapmakers and GIS analysts use them to calculate accurate distances. And telecom planners follow great circles when laying undersea cables to reduce cost and signal delay. Even military strategists use them for missile trajectories and surveillance planning.
