A receiver is provided for use with a satellite navigation system comprising a constellation of multiple satellites. Each satellite transmits a signal incorporating a spreading code. The receiver includes at least one code storage unit that includes combinatorial logic for storing a memory code comprising a fixed pattern of bits including address decoding, wherein the stored memory code corresponds to a spreading code incorporated into a signal transmitted from a satellite. The receiver further includes a correlator for performing a correlation between an incoming signal and the stored spreading code from the one code storage unit.
L'invention concerne un récepteur à utiliser avec un système de navigation par satellite qui comprend une constellation de plusieurs satellites. Chaque satellite émet un signal incorporant un code d'étalement. Le récepteur comporte au moins une unité de stockage de codes qui renferme une logique combinatoire pour stocker un code mémoire comprenant un motif fixe de bits comportant le décodage d'adresse, le code mémoire stocké correspondant à un code d'étalement incorporé dans un signal émis d'un satellite. Le récepteur comporte en outre un corrélateur qui exécute une corrélation entre un signal entrant et le code d'étalement stocké à partir de l'unité de stockage de codes.
