GPS, a device known as Global Positioning System is a tool used for tracking locations, finding routes for certain places and for finding the position of objects, people and yourself. This device uses a satellite based network to provide you with necessary information to a certain place or location you wish to go to. This technology uses signals that are transmitted from satellites to the earth which are captured by monitoring stations on the earth then sent to the receivers called GPS. The information provided is as accurate to 3 meters therefore making it quite precise in its measurements compared to other devices. Once a GPS has found your position, it can also find the speed, distance; acceleration and the time the trip will take in total.
How does a GPS work?
GPS work with the help of 24 satellites that orbit around the earth 12000 miles above. They provide each segment of the earth coverage so that a location can be obtained by a simple method called Trilateration. This method allows us to acquire our location by using signals from 3 satellites that cover our area. The GPS simply finds the location of the three satellites plus the distance of the device and the three satellites by radio signals. It is then transmitted to the GPS by radio waves to provide you with an address, a street view of the location or a satellite view of the location you wish to see.
If a direction or specific route is wanted, a GPS can provide you with directions from the position you are at to the destination wanted. It will obtain information from the destination you wish to be at plus your location at the moment and it will form a possible route that may be taken to arrive to that destination.
This technology has also been developed to work on cellular devices such as smartphones. Now, people are able to use a technology similar to a GPS called an A-GPS with their cellular data to provide them with locations and routes but this
