Abstract
L'invention concerne un récepteur de navigation en système LORAN-C. Elle se rapporte à un récepteur léger, peu encombrant et peu coûteux dont l'antenne 2 reçoit des signaux transmis à un filtre 1, un détecteur 6 de passage à 0 déterminant le passage à 0 vers les valeurs positives du troisième cycle des impulsions des émetteurs du système et transmettant la valeur à une bascule 5. Les valeurs permettent la détermination précise des différences des temps d'arrivée entre les impulsions des trains des différents émetteurs, les différences de temps étant comparées avec des valeurs convenables affichées à l'aide de commutateurs 11. Application à la navigation dans les aéronefs et les bateaux.
