Geolocation by satellite
there Geolocation is a process that determines the geographic position of a fixed or mobile object or person on the Earth's surface. there geolocation by satellite works according to the principle of triangulation. The position of the object to be geolocated is calculated by the signals exchanged between the receiver equipped with the geolocation device and a set of satellites with a minimum of three. Measuring the travel time of these signals can be used to identify the longitude, latitude and altitude of the object with an accuracy of 10 to 5 meters.
There are different satellite geolocation systems. There is the Russian system called GLONASS which has been operational since 2010 and covers 100% of the planetary surface. The European system called GALILEO has been fully functional since 2014 and offers great precision. The Chinese system, BEIDOU, has also been operational since 2011. The most well-known system to date is the GPS launched by the United States and it works globally. The majority of satellite geolocation devices in the world work with GPS, whether it is GPS tracker car, the GPS beacon motorcycle or child GPS snitch.
