What is GPS?
GPS is the acronym for Global Positioning System, and consists of satellite tracking technology.
GPS is a satellite navigation system from a mobile device, which sends information about the position of something at any time and in any weather condition.
Originally, GPS was created in 1973 to facilitate navigation systems. Currently, there are two types of satellite navigation systems: the American GPS, which was initially only in military (and now citizens already have access) and Russian GLONASS.
The GPS system works thanks to a set of 24 satellites that surround the Earth at an altitude of approximately 20,200 km and at a speed of almost 11,500 km / h. Everywhere in the world, the receiving device (the GPS device) picks up information from a group of four of these satellites and, by exchanging some data and algorithms, is able to determine for the user his exact location on the map.
Nowadays, GPS is used in the most diverse aspects of people’s daily lives, be it navigational guidance (in aviation, sea or car) or to find a specific location on the map.
GPS has the main function of finding the way to a certain place, knowing the speed and direction of its displacement. Currently, this system is widely used in automobiles, with a map system that greatly facilitates the discovery of faster paths between two points, for example.
