摘要：A great circle route (GCR) is the shortest route on a spherical earth model.Do we have a visual diagram to handle the shortest route? In this paper,a graphical method (GM) is proposed to solve the GCR problems based on the celestial meridian diagram (CMD) in celestial navigation.Unlike developed algebraic methods,the GM is a geometric method.Appling computer software to graph,the GM does not use any equations but is as accurate as using algebraic methods.In addition,the GM,which emphasizes the rotational surface,can depict a GCR and judge its benefit.
