Global Positioning Systems, also known as GPS systems, can be found almost everywhere nowadays. They use the satellites so they can send signals on the surface of the Earth, signals that are intercepted by the so called GPS receivers. The official name of the GPS is NAVSTAR GPS, which was given by John Walsh. The GPS satellites have atomic clocks because the system in based on time synchronization with all the existent GPS units. Starting with 1983 the GPS is used on a large scale and not only by the government, which allowed scientists to benefit from its help too.
