The invention relates to a satellite-based positioning system in which a transmitter (2) emits electromagnetic radiation at least at N >= 3 carrier frequencies (3, 4, 5). In order to resolve the phase ambiguity for said satellite-based positioning system, the electromagnetic radiation is received by a receiver (1), and K pseudo paths (3a, 4a, 5a, 6a) and L carrier phases (3b, 4b, 5b, 6b), especially at least two pseudo paths (3a, 5a) and at least two carrier phases (3b, 4b), are derived from the received radiation as M pieces of distance data, wherein M = K + L. In order to determine the position, the integer phase ambiguity is derived from the linear combination of a maximum of M <= 2N-1 pieces of distance data.
L'invention concerne un système de positionnement par satellite comportant une unité d'émission (2) émettant un rayonnement électromagnétique présentant au moins N = 3 fréquences de porteuses (3, 4, 5). Pour la détermination d'ambiguïté de phase, une unité de réception (1) reçoit le rayonnement électromagnétique et dérive K pseudo-voies (3a, 4a, 5a, 6a) et L phases de porteuses (3b, 4b, 5b, 6b) en tant que M informations de distance (M = K + L), notamment au moins deux pseudo-voies et au moins deux phases de porteuses (3b, 4b), à partir du rayonnement reçu. Pour la détermination de position, l'ambiguïté de phase entière est dérivée à partir de la combinaison linéaire de M = 2N - 1 informations de distance au maximum.
