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. 

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. 

The Police 

Officers in the Royal Canadian Mounted Police (RCMP) use a variety of math concepts everyday in their line of work. They use math while on patrol and more specifically in accident reconstruction and crime scene investigation.
