(Ottawa, Ontario, Canada, 2 juin 2025) Calian GNSS, leader mondial des technologies GNSS et RF de pr\u00e9cision, est fier d’annoncer le lancement de son antenne \u00e0 diagramme de r\u00e9ception contr\u00f4l\u00e9 (CRPA) anti-brouillage de nouvelle g\u00e9n\u00e9ration. La CR8894SXF+ est une CRPA avanc\u00e9e, con\u00e7ue pour fournir une protection efficace contre les interf\u00e9rences et une connaissance de la situation en temps r\u00e9el dans les infrastructures critiques, la marine et les environnements de d\u00e9fense o\u00f9 la continuit\u00e9 du GNSS est essentielle \u00e0 la mission. L’antenne CRPA est sp\u00e9cialement con\u00e7ue pour fournir une solution l\u00e9g\u00e8re et de faible puissance dans un format compact. <\/p>\n\n\n\n

Con\u00e7ue pour les applications \u00e0 haute r\u00e9silience, l’antenne CRPA CR8894SXF+ utilise une formation de nullit\u00e9 avanc\u00e9e dans la bande. Ce nouveau mod\u00e8le \u00e0 montage en surface est con\u00e7u pour prot\u00e9ger les signaux GPS L1\/L2 et Galileo E1\/E5b, garantissant un positionnement, une navigation et une synchronisation (PNT) r\u00e9silients dans les environnements RF contest\u00e9s, encombr\u00e9s et d\u00e9grad\u00e9s. Con\u00e7ue avec la technologie d’att\u00e9nuation des interf\u00e9rences eXtended Filtering (XF+) de Calian, leader sur le march\u00e9, l’antenne offre performance et fiabilit\u00e9 en pr\u00e9sence de menaces RF. <\/p>\n\n\n\n

Le CRPA combine une formation de nullit\u00e9 dans la bande (20-40 dB) avec une puissante r\u00e9jection hors bande (jusqu’\u00e0 80 dB) de 700 MHz \u00e0 2500 MHz et dispose de deux canaux ind\u00e9pendants d’amplificateur \u00e0 faible bruit (LNA) – ainsi, si une bande de signal est compromise, le second canal maintient l’int\u00e9grit\u00e9 op\u00e9rationnelle.<\/p>\n\n\n\n

L’antenne forme des z\u00e9ros dans les bandes GNSS sup\u00e9rieures (L1\/E1) et inf\u00e9rieures (L2\/E5b) pour supprimer activement les sources de brouillage. Une interface de sortie s\u00e9rie int\u00e9gr\u00e9e fournit un retour d’information en temps r\u00e9el, permettant aux utilisateurs de surveiller les conditions RF et l’\u00e9tat du syst\u00e8me. Les sorties comprennent : <\/p>\n\n\n\n

– \u00c9tat de l’ACRP<\/strong>: ouvert (pas de brouillage), prot\u00e9g\u00e9 (brouillage att\u00e9nu\u00e9) ou ferm\u00e9 (brouill\u00e9 mais prot\u00e9g\u00e9)– Caract\u00e9risation du brouilleur<\/strong>: angles d’azimut et d’\u00e9l\u00e9vation des sources de brouillage d\u00e9tect\u00e9es– R\u00e9sum\u00e9 des signaux de menace<\/strong>: offre une \u00e9valuation rapide de la menace pour le commandement et le contr\u00f4le<\/p>\n\n\n\n

Ces caract\u00e9ristiques am\u00e9liorent consid\u00e9rablement la connaissance de la situation, permettant aux op\u00e9rateurs de syst\u00e8mes de maintenir des op\u00e9rations s\u00e9curis\u00e9es et ininterrompues bas\u00e9es sur le GNSS dans des environnements \u00e0 haut risque.<\/p>\n\n\n\n

La s\u00e9rie CRPA de Calian vise \u00e0 \u00e9tablir une nouvelle r\u00e9f\u00e9rence en mati\u00e8re de r\u00e9silience op\u00e9rationnelle, en offrant une protection et une intelligence avanc\u00e9es pour les applications GNSS critiques.<\/p>\n\n\n\n
