Question

In which area GPS used ?

Answer 1

Your imagination is the only limitation to the possibilities of global positioning system (GPS) technologies. GPS systems are extremely versatile and can be found in almost any industry sector. They can be used to map forests, help farmers harvest their fields, and navigate airplanes on the ground or in the air. GPS systems are used in military applications and by emergency crews to locate people in need of assistance. GPS technologies are often working in many areas that we do not normally consider.
Global positioning system applications generally fall into 5 major categories:
1. Location - determining a position 
2. Navigation - getting from one location to another 
3. Tracking - monitoring object or personal movement 
4. Mapping - creating maps of the world 
5. Timing - bringing precise timing to the world
