Spheroidal Distance evaluator uses Spheroidal Distance = Reduced Distance+((Reduced Distance^3)/(24*Earth Radius in km^2)) to evaluate the Spheroidal Distance, The Spheroidal Distance formula is defined as the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior). Spheroidal Distance is denoted by S symbol.
