The Global Positioning System and Circles 

The Global Positioning System is based on common mathematical equations of distance and speed. Trilateration enables GPS receivers to find the latitude, longitude, and altitude of a receiver, anywhere on the earth. 

Lithotripsy  A Medical Application of the Ellipse 

Lithotripsy is the process of fragmenting painful kidney stones. The lithotripter is successful because of the reflective property of an ellipsoid. 

Long Range Navigation System 

Three stations, located along the coast, use hyperbolics branches to locate ships at sea. This system is known as Long Range Navigation (Loran). 

Navigation 

Two successful navigation systems known as Loran (Long Range Navigation) and GPS (Global Positioning System) are based on the principles of the hyperbola and the circle, as well as the idea of trilateration. 

Suspension Bridges 

Suspension Bridges encompass many mathematical concepts including its parabolic shape, the length and measurements of the bridge, the forces acting on the bridge, and elements of weather.
