Abstract
(EN) A method for determining a state parameter of a global navigation satellite system receiver and an apparatus, in particular its absolute position, determining being based on - a measured information including a pseudorange, a carrier phase and/or a Doppler frequency measurement, - broadcast information on the satellite orbits and clock offsets, and - high accuracy correction information of a satellite positions, clock offsets, code and/or phase biases, the method comprising: - determining a satellite position estimate and a clock offset estimate based on the broadcast information, - determining a corrected satellite position and a corrected clock offset based on the satellite position estimate and the clock offset estimate by using the high accuracy information, in particular the high accuracy correction information of the satellite position and the clock offset.
(FR) L'invention concerne un procédé de détermination d'un paramètre d'état d'un récepteur de système global de navigation par satellite, en particulier sa position absolue, et un appareil, la détermination étant basée sur : une information mesurée comprenant une pseudodistance, une phase porteuse et/ou une mesure de fréquence Doppler, des informations de diffusion sur les orbites des satellites et le décalage des horloges, et des informations de correction de haute précision des positions des satellites, du décalage des horloges, du code et/ou des biais de phase, le procédé comprenant : la détermination d'une estimation de la position du satellite et d'une estimation du décalage des horloges sur la base des informations de diffusion, la détermination d'une position corrigée du satellite et d'un décalage corrigé des horloges sur la base de l'estimation de la position du satellite et de l'estimation du décalage des horloges en utilisant les informations de haute précision, en particulier les informations de correction de haute précision de la position du satellite et du décalage des horloges.
