L’AJ977XF prend en charge les bandes de fr\u00e9quences GPS\/QZSSL1\/L2\/L5, GLONASS-G1\/G2\/G3, Galileo-E1\/E5a\/E5b, BeiDou-B1\/B2a\/B2b et NavIC-L5, y compris le syst\u00e8me de renforcement par satellite (SBAS) disponible dans la r\u00e9gion d’exploitation [WAAS (Am\u00e9rique du Nord), EGNOS (Europe), MSAS (Japon) ou GAGAN (Inde)].<\/p>\n\n

L’antenne anti-brouillage AJ977XF est con\u00e7ue pour att\u00e9nuer les interf\u00e9rences et les signaux de brouillage \u00e9mis par des \u00e9metteurs terrestres proches. Le diagramme de rayonnement de l’antenne d’annulation \u00e0 faible angle d’\u00e9l\u00e9vation (LEANA) offre une suppression \u00e0 large bande de 20 dB (typique) pour tous les signaux de la bande GNSS re\u00e7us \u00e0 un angle d’\u00e9l\u00e9vation de 0\u00b0 \u00e0 environ 15\u00b0. Ce niveau d’att\u00e9nuation permet d’att\u00e9nuer un signal de brouillage de 600 watts diffus\u00e9 \u00e0 un angle d’\u00e9l\u00e9vation de 10\u00b0, \u00e0 100 m ou plus de l’antenne AJ977XF. La combinaison du mod\u00e8le de rayonnement \u00e0 faible angle d’\u00e9l\u00e9vation de Tallysman et des technologies de filtrage \u00e9tendu (filtres profonds et IP3 \u00e9lev\u00e9 (emp\u00eache la saturation en pr\u00e9sence de bruit)) offre un double coup de poing contre le brouillage et le bruit des fr\u00e9quences radio. En m\u00eame temps, le diagramme de rayonnement de l’AJ977XF au-dessus d’un angle d’\u00e9l\u00e9vation de 20\u00b0 offre un excellent gain et un centre de phase qui permet un positionnement pr\u00e9cis et exact.<\/p>\n\n

La technologie d’antenne eXtended Filter (XF) de Tallysman a \u00e9t\u00e9 con\u00e7ue pour att\u00e9nuer les signaux hors bande et emp\u00eacher la saturation de l’antenne GNSS. En Am\u00e9rique du Nord, les signaux Ligado \u00e0 1525 – 1536 MHz peuvent avoir un impact particulier sur les antennes GNSS qui prennent en charge les services de correction en bande L bas\u00e9s dans l’espace (1539 – 1559 MHz). Les nouveaux signaux LTE en Europe [bande 32 (1452 – 1496 MHz)] et au Japon [bandes 11 et 21 (1476 – 1511 MHz)] ont \u00e9galement \u00e9t\u00e9 observ\u00e9s comme interf\u00e9rant avec les signaux GNSS. En outre, les communications par satellite Inmarsat (liaison montante : 1626,5 – 1660,5 MHz) peuvent \u00e9galement affecter les signaux GNSS. Le filtrage XF personnalis\u00e9 de Tallysman att\u00e9nue tous les signaux existants et les nouveaux signaux Ligado et LTE, ce qui permet aux antennes et aux r\u00e9cepteurs GNSS connect\u00e9s de fonctionner de mani\u00e8re optimale.<\/p>\n\n

L’antenne Tallysman AJ977XF est id\u00e9ale pour toutes les applications critiques de positionnement, de navigation et de synchronisation.<\/p>\n\n
