Title (EN) IMPROVED GNSS RECEIVER USING A COMBINATION OF VELOCITY INTEGRATION AND PRECISE POINT POSITIONING
(FR) RÉCEPTEUR GNSS AMÉLIORÉ UTILISANT UNE COMBINAISON D'INTÉGRATION DE VITESSE ET DE POSITIONNEMENT DE POINT PRÉCIS
Abstract:
(EN) The invention discloses an improved GNSS receiver which determines a location of the receiver by combining a first location determined from the standard PVT of a multi-frequency receiver and a second location determined by integrating the velocity from the standard PVT. The combination is based on a duty cycle or a combination of the duty cycle with a weighting of the error budgets of the first position and the second location. The improved receiver is preferably based on a standard receiver with an add-on software module which receives and processes data transmitted from the standard receiver by, for example, NMEA messages. The improved receiver allows a determination of a more precise and smoother trajectory in a simple way.
(FR) L'invention concerne un récepteur GNSS amélioré qui détermine un emplacement du récepteur en combinant un premier emplacement déterminé à partir du PVT standard d'un récepteur multi-fréquence et un second emplacement déterminé par intégration de la vitesse à partir du PVT standard. La combinaison est basée sur un cycle de service ou une combinaison du cycle de service avec une pondération des budgets d'erreur du premier emplacement et du second emplacement. Le récepteur amélioré est de préférence basé sur un récepteur standard avec un module logiciel complémentaire qui reçoit et traite des données émises par le récepteur standard par, par exemple, des messages NMEA. Le récepteur amélioré permet de déterminer une trajectoire plus précise et plus régulière d'une manière simple.
