Abstract

L'invention concerne un procédé de transformation d'une indication d'au moins une position sur un globe terrestre d'un premier système de coordonnées terrestre dans un second système de coordonnées local. La position dans le premier système de coordonnées terrestre peut être indiquée en longitude et en latitude et la position dans le second système de coordonnées local peut être indiquée par rapport à deux axes orientés orthogonalement l'un à l'autre. Le procédé comprend les étapes consistant à : - recevoir un signal contenant une indication de la position au moyen d'une antenne, - déterminer une première distance (x) entre la position et une longitude de référence pour le premier axe local au moyen d'une unité de calcul, et - déterminer une seconde distance (y) entre la position et la latitude de référence pour le second axe local au moyen de l'unité de calcul. L'invention est caractérisée en ce que la longitude de référence est sélectionnée de façon à se trouver au voisinage de la position.
