Abstract
(EN) Apparatus and methods for resolving integer ambiguities in position determination. An embodiment of the invention includes a reference system, augmented with multi-frequency pseudolites using a carrier phase differential GPS implementation, and a mobile system. In one embodiment, the components of the reference system include one or more multi-frequency pseudolites, one or more multi-frequency reference receivers, a data link standing alone or built into the pseudolites, and the associated antennae for each of these elements. The components of the reference system may be stationary. The mobile system may include a multi-frequency receiver and its associated antennae. Because the mobile systems may passively receive information, an unlimited number of mobile systems may be included in any given embodiment of the invention. A multi-frequency pseudolite uses a single frequency source to synthesize all of the multiple carrier frequencies and all of the multiple base band signals modulated onto carrier frequencies for transmission.
(FR) L'invention concerne un appareil et des procédés permettant la résolution des ambiguïtés de longueurs d'onde entière dans la détermination de position. Dans un mode de réalisation de l'invention, ledit appareil comprend un système de référence complété par des pseudolites à fréquences multiples, par la mise en oeuvre d'un GPS différentiel à décalage de porteuse, et un système mobile. Dans un mode de réalisation, les composants du système de référence comportent un ou plusieurs pseudolites, un ou plusieurs récepteurs de référence à fréquences multiples, une liaison de données séparée ou intégrée aux pseudolites et les antennes associées pour chacun de ces éléments. Les composants du système de référence peuvent être stationnaires. Le système mobile peut inclure un récepteur multifréquence et ses antennes associées. Etant donné que les systèmes mobiles peuvent recevoir passivement des informations, un nombre illimité de systèmes mobiles peut être inclus dans n'importe quel mode de réalisation de l'invention. Un pseudolite multi-fréquence utilise une seule source de fréquence pour synthétiser la totalité des multiples fréquences porteuses et des multiples signaux dans la bande de base modulés sur les fréquences porteuses en vue de leur transmission.
