Title (EN) SATELLITE NAVIGATION RECEIVER AND METHOD FOR SWITCHING BETWEEN REAL-TIME KINEMATIC MODE AND RELATIVE POSITIONING MODE
(FR) RÉCEPTEUR DE NAVIGATION PAR SATELLITE ET PROCÉDÉ DE COMMUTATION ENTRE MODE CINÉMATIQUE EN TEMPS RÉEL ET MODE DE POSITIONNEMENT RELATIF
Abstract:
(EN) An offset module (130) or navigation positioning estimator (57) determines a reference frame bias between precise point positioning (PPP) reference frame and an RTK reference frame, where the PPP reference frame is associated with relative position estimates generated by the relative position estimator (124) and where the RTK reference frame is associated RTK position estimates generated by the RTK position estimator (122). Upon loss of the RTK correction signal, the navigation positioning estimator (57) or controller switches to a relative position mode based a last available RTK position. The relative position estimator (124) determines an estimated relative position based on time-differenced phase measurements by the mobile receiver (12, 30) in the relative position mode. The relative position estimator (124) or offset module (130) offsets the estimated relative position in the relative position mode.
(FR) Selon l'invention, un module de décalage (130) ou un estimateur de positionnement de navigation (57) détermine une polarisation de trame de référence entre une trame de référence de positionnement de point précis (PPP) et une trame de référence RTK, la trame de référence PPP étant associée à des estimations de position relative générées par l'estimateur de position relative (124) et la trame de référence RTK étant associée à des estimations de position RTK générées par l'estimateur de position RTK (122). Lors d'une perte du signal de correction RTK, l'estimateur de positionnement de navigation (57) ou le dispositif de commande commute en un mode de position relative, sur la base d'une dernière position RTK disponible. L'estimateur de position relative (124) détermine une position relative estimée sur la base de mesures de phase à différenciation dans le temps par le récepteur mobile (12, 30) dans le mode de position relative. L'estimateur de position relative (124) ou le module de décalage (130) décale la position relative estimée dans le mode de position relative.
