Since October 12, 2017, after a good month of testing, G\u00e9odata Diffusion has therefore expanded its service offer by offering real-time Full GNSS NRTK corrections compatible with GPS, GLONASS, Galileo and BeiDou.<\/p>

Full GNSS<\/h2>

Full GNSS (for Geolocation and Navigation by a Satellite System) is a term that designates positioning equipment or installations capable of using all the satellite constellations available for their calculations.<\/p>

Different satellites<\/h2>

Until today, we used the generic term GPS for Global Positioning System to describe the various geopositioning equipment.<\/p>

However, this term is actually the name of a set of 24 American satellites placed in orbit at an altitude of 20,000 km. This constellation of satellites, which was the first in history, therefore left its name to geopositioning technology.<\/p>

These satellites revolve around the earth and are therefore in constant motion. To establish a position, a minimum of 5 satellites is required.
Other constellations of satellites have thus been put into service by other countries:<\/p>
