GPS in society

If you go back about 50 years we a hardly had any technology now we have phones, Televisions and GPS'. GPS' play an huge role in todays society, If you are lost you can use a GPS to find your destination. A GPS is a system that accurately determines the precise position of something on earth. There are three different elements of GPS' in the United States today. One is that satellites in predetermined orbits, Tracking stations to monitor and control satellites and, a receiver that can locate at least 4 satellites. There are also many applications of GPS' including Turn by turn directions in vehicles, Navigational aid to planes and ship captains,  and, provide location to social media applications in a smartphone. Personally I do not think I'd like places to know my location and information. However I do like it when a GPS tells us how far away we are from the closest location we entered.
