Our aim is to always offer you the best solution. At EPOSA, you receive positioning data of the highest quality and accuracy. We achieve this by utilizing all four global navigation satellite systems (GNSS): the American GPS, the Russian GLONASS, the European Galileo, and the Chinese BeiDou
Precise position determination in seconds
The use of these satellite systems enables precise, real-time positioning. The satellites orbit the Earth at altitudes of approximately 20,000 to 30,000 kilometers. From there, they transmit digital signals. These signals are received by local GNSS receivers (rovers) in the EPOSA network and converted into coordinates.
This is how satellite transmission works
The satellite signals are received by both the GNSS receiver and the EPOSA reference stations. The position can be determined based on their distance. Correction data is used for even more precise results. This data is derived from measurements taken by two receivers located close to each other.
This method is also called "Differential Global Navigation Satellite System" (DGNSS or DGPS). The combination of directly received signals and correction data results in a highly accurate position for the user. The correction data is transmitted via mobile network.
