A method for collaborative determination of satellite navigation system positioning errors The aim of the invention is to produce information making it possible to determine the positioning errors resulting from the satellite navigation signal use by generating a map of the ionospheric errors of sufficient precision from terminals receiving GNSS signals. The position may not be known precisely.
A method for collaborative determination of satellite navigation system positioning errors Publicity - Better positioning leads to better advertising targeting Agriculture - The accuracy of the map makes the sensors more efficient and increases productivity Access to new data - Processing of new signals from smartphones previously inaccessible Improved performance - Increased convergence speed (faster positioning) - More precise positioning New ionospheric maps - New, more accurate maps
Smartphones - Interesting convergence speed for smartphones GPS positioning Advertising - Geotagged advertising Sports et leisures - Interesting precision when hikes or excursions in hostile environment Agriculture - Management of agricultural sensors
