Zusammenfassung: | The invention relates to a method for measuring the position of a device based on a network of satellites in a predictive system comprising a filter with a variable gain K, said gain K being represented by a vector of variable gain coefficients, said method, which is implemented by the device, comprising, in particular in each iteration following a time t, the steps of minimizing the expectation of the square of the innovation of the filter at the time t+1, the innovation being computed based on the coefficients of the gain, in order to improve the accuracy of the positioning.
L'invention concerne un procédé de mesure de la position d'un dispositif à partir d'un réseau de satellites dans un système prédictif à filtre de gain K variable, ledit gain K étant représenté par un vecteur de coefficients de gain variables, ledit procédé, mis en œuvre par le dispositif, comprenant notamment à chaque itération suivant un instant t les étapes de minimisation de l'espérance du carré de l'innovation du filtre à l'instant t+1, l'innovation étant calculée à partir des coefficients du gain, afin d'améliorer la précision du positionnement. |
