Title (EN) A METHOD OF ANALYSING MULTIPLE SIGNALS TRANSMITTED BY DISCRETE GLOBAL NAVIGATION SATELLITE SYSTEMS
(FR) PROCÉDÉ D'ANALYSE DE MULTIPLES SIGNAUX ÉMIS PAR DES SYSTÈMES MONDIAUX DE SATELLITES DE NAVIGATION DISCRETS
Abstract:
(EN) The present disclosure provides a method of analysing multiple signals transmitted by multiple discrete global navigation satellite systems for identifying information to be combined and delivered to a single-receiver user for use in an application. The method comprises analysing each of the signals to identify observed quantities of the signal. The observed quantities comprise information tracked by a network of receivers or by a single receiver. The method further comprises formulating full-rank observation equations from the observed quantities and determining inter-system biases (ISB) existing between the discrete satellite systems. In addition, the method comprises incorporating the inter-system biases into the full-rank observation equations to yield ISB-corrected observation equations, thereby allowing the multiple discrete global navigation satellite systems to be represented as a single global navigation satellite system and delivering the ISB-corrected observation equations to the single-receiver user.
(FR) La présente invention concerne un procédé d'analyse de multiples signaux émis par de multiples systèmes mondiaux de satellites de navigation discrets pour identifier des informations devant être combinées et distribuées à un utilisateur de récepteur unique pour une utilisation dans une application. Le procédé consiste à analyser chacun des signaux pour identifier des quantités observées du signal. Les quantités observées comprennent des informations suivies par un réseau de récepteurs ou par un seul récepteur. Le procédé consiste en outre à formuler des équations d'observation de rang entier à partir des quantités observées et à déterminer des polarisations inter-systèmes (ISB) existant entre les systèmes de satellites discrets. De plus, le procédé consiste à incorporer les polarisations inter-systèmes dans les équations d'observation de rang entier pour produire des équations d'observation à ISB corrigée, permettant ainsi aux multiples systèmes mondiaux de satellites de navigation discrets d'être représentés en tant que système mondial de satellites de navigation unique et de distribuer les équations d'observation à ISB corrigée à l'utilisateur de récepteur unique.
