How does a GPS tracker work?

a GPS tracker is a small device that, once emblaped on a person, animal or moving object, can be used to know your geographical location. And all this, thanks to geographical coordinates, which can be found in latitude and longitude. To achieve this result, the GPS tracker goes through a few steps. 


Get geographic coordinates via satellites

there Geolocation is made possible by a network of 24 satellites, dispersed and orbiting the Earth, the global positioning system. Originally intended for military use, this technology was made public from the mid-1990s. The GPS tracker is actually a case that is related to this network of satellites to determine its position from space. The data emitted by the satellite then passes through operators on Earth before being sent to the GPS tracker. As we have seen, location data is expressed in latitude and longitude; they can be located anywhere on the surface of the globe. Fortunately, at this point, they can easily be interpreted by entering them on Googlemap, for example. To do this, some devices store this data in a memory card for the user to retrieve. For others, they send them.


Send location data to the user

At this point, the different types of GPS trackers use various techniques to send their geographical positions, duly obtained from satellites. The only common thread is the objective: to send real-time geolocation data. Some GPS devices use a SIM card to send in the form of sms messages. The most sophisticated use the internet to send them to a server: The user can view the tracker's positions from an account on a website or mobile app (service provided by the manufacturer).
