Abstract
(EN)
The present invention relates to a method for determining a position of an object having a Global Navigation Satellite System (GNSS) receiver. According to the invention, the method comprises the steps of: receiving signals by the GNSS receiver which are transmitted by GNSS transmitters positioned on board of satellites which are positioned in a view of the object; updating service data in the object, the service data including satellite clock data indicating internal clocks of the satellites, satellite orbit data indicating positions of the satellites, satellite delay code bias data relating to delay code biases of the GNSS transmitters and ionospheric model data indicating a state of an ionosphere; determining, based on the ionospheric model data, ionospheric delay data indicating corrections relating to delays of the signals, the delays of the signals resulting from a passage of the signals through the ionosphere between transmission of the signals from the GNSS transmitters and reception of the signals by the GNSS receiver; and determining a position of the object based on the signals, the satellite clock data, the satellite orbit data, the satellite delay code bias data and the determined ionospheric delay data.

La présente invention porte sur un procédé pour déterminer une position d'un objet ayant un récepteur de géolocalisation et navigation par un système de satellites (GNSS). Selon l'invention, le procédé comprend les étapes consistant à : recevoir des signaux par le récepteur GNSS qui sont transmis par des émetteurs GNSS positionnés à bord de satellites qui sont positionnés dans une vue de l'objet ; mettre à jour des données de service dans l'objet, les données de service comprenant des données d'horloge de satellite indiquant des horloges internes des satellites, des données d'orbite de satellite indiquant des positions des satellites, des données de biais de code de retard de satellite relatives à des biais de code de retard des émetteurs GNSS et des données de modèle ionosphérique indiquant un état d'une ionosphère ; déterminer, sur la base des données de modèle ionosphérique, des données de retard ionosphérique indiquant des corrections relatives à des retards des signaux, les retards des signaux résultant d'un passage des signaux à travers la ionosphère entre l'émission des signaux à partir des émetteurs GNSS et la réception des signaux par le récepteur GNSS ; et déterminer une position de l'objet sur la base des signaux, des données d'horloge de satellite, des données d'orbite de satellite, des données de biais de code de retard de satellite et des données de retard ionosphérique déterminées.
