Abstract
(EN)
The present invention pertains to the field of radio-navigation and essentially relates to generators for generating a code of pseudo-random sequences. These generators can be used as reference code generators during the digital correlation processing of signals in multi-channel receivers for receiving pseudo-noise signals from the GPS and GLONASS satellite radio-navigation systems (SRNS). The purpose of this invention is to provide a generator for generating a code of pseudo-random sequences for the SNRS that has two modes of operation, i.e. a mode for generating a code of pseudo-random sequences for the GPS system and a mode for generating a code of pseudo-random sequences for the GLONASS system. The common elements of the generator are used for generating both codes, which simplifies the structure and reduces the number of components in the equipment used. This result can be achieved by an optimisation of the connection and interaction between the standard components of the generator.

Cette invention se rapporte au domaine de la radionavigation, et concerne des générateurs de code de séquences pseudo-aléatoires. Ces générateurs peuvent être utilisés comme générateurs de codes de référence lors du traitement de corrélation numérique de signaux dans des récepteurs à canaux multiples qui reçoivent des signaux de pseudo-bruit provenant des systèmes de radionavigation satellite (SRNS) GPS et GLONASS. Cette invention a pour but de créer un générateur de code de séquences pseudo-aléatoires pour les SRNS qui peut fonctionner selon deux modes, plus précisément selon un mode de génération de code de séquences pseudo-aléatoires pour le système GPS, et selon un mode de génération de code de séquences pseudo-aléatoires pour le système GLONASS. Les éléments communs du générateur participent à la génération des deux codes, ce qui permet de simplifier la structure et de réduire le nombre des composants de l'équipement utilisé. Ce résultat est obtenu par une optimisation de la connexion et de l'interaction des composants standards du générateur.
