A track model is created for use with a GPS receiver. In one embodiment, the track model is a set of planar surfaces [Fig. 1, item 170] which approximate the contiguous surface on which navigation takes place [item 160]. The GPS receiver searches for an appropriate planar surface associated with its approximate position [item 166]. Having found the appropriate planar surface, the GPS receiver constrains its position using the planar surface associated with its approximate position. Using the track model improves the accuracy of the computed position at the time and improves the ambiguity estimation process so that positions with greatly improved accuracy are available sooner.

Selon cette invention, on crée un modèle de poursuite devant être utilisé avec un récepteur GPS. Dans un premier mode de réalisation, le modèle de poursuite est un ensemble de surfaces planaires qui ressemblent à la surface contiguë sur laquelle s'effectue la navigation. Le récepteur GPS recherche une surface planaire appropriée associée à sa position approximative. Lorsqu'il trouve la surface planaire appropriée, le récepteur GPS délimite sa position en faisant intervenir la surface planaire associée à la position approximative. L'utilisation du modèle de poursuite multiplie la précision de la position calculée à ce moment là et améliore le processus d'estimation de l'ambiguïté de manière à obtenir des positions très précises plus rapidement.
