Antenne bibande multi-constellation int\u00e9gr\u00e9e<\/p>\n\n

Le TW3887XF est une antenne Accutenna\u00ae bi-bande \u00e0 r\u00e9glage pr\u00e9cis qui couvre les syst\u00e8mes GPS\/QZSS-L1\/L2, GLONASS-G1\/G2, Galileo-E1 et BeiDou-B1, 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

Le TW3887XF est dot\u00e9 d’un amplificateur \u00e0 faible courant et \u00e0 faible bruit (LNA) \u00e0 la pointe de l’industrie, qui comprend un pr\u00e9-filtre int\u00e9gr\u00e9 \u00e0 faible perte pour emp\u00eacher les interf\u00e9rences harmoniques provenant de signaux \u00e0 forte amplitude, tels que les signaux LTE de la bande 700 MHz et d’autres signaux cellulaires \u00e0 bande proche. Le spectre des fr\u00e9quences radio \u00e9tant de plus en plus encombr\u00e9, les signaux et les fr\u00e9quences harmoniques des nouvelles bandes LTE [par exemple 800 MHz x 2 = 1600 MHz (GLONASS-G1)] peuvent affecter les antennes et les r\u00e9cepteurs GNSS. En Am\u00e9rique du Nord, les signaux Ligado pr\u00e9vus \u00e0 1525 – 1536 MHz pourraient avoir un impact particulier sur les antennes GNSS qui prennent en charge les corrections en bande L bas\u00e9es 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. Les nouvelles antennes Tallysman XF ont \u00e9t\u00e9 con\u00e7ues pour att\u00e9nuer les signaux hors bande et emp\u00eacher la saturation des antennes GNSS. Le filtrage XF personnalis\u00e9 de Calian att\u00e9nue tous les signaux existants et les nouveaux signaux Ligado et LTE, permettant aux antennes et aux r\u00e9cepteurs GNSS connect\u00e9s de fonctionner de mani\u00e8re optimale.Id\u00e9al pour les capteurs de contr\u00f4le des trains, le suivi et le guidage des v\u00e9hicules autonomes, l’agriculture de pr\u00e9cision et d’autres applications o\u00f9 la pr\u00e9cision est importante, le TW3887XF offre une r\u00e9jection sup\u00e9rieure des signaux \u00e0 trajets multiples, une r\u00e9ponse de phase lin\u00e9aire et une faible variation du centre de phase (PCV).<\/p>\n\n

Le TW3887XF est dot\u00e9 d’un \u00e9l\u00e9ment de patch empil\u00e9 \u00e0 double alimentation circulaire, accord\u00e9 avec pr\u00e9cision. Les signaux provenant des deux alimentations orthogonales sont combin\u00e9s dans un combinateur hybride, amplifi\u00e9s dans un LNA \u00e0 large bande, puis divis\u00e9s en bandes pour un filtrage \u00e9troit dans chaque bande et encore amplifi\u00e9s avant d’\u00eatre recombin\u00e9s \u00e0 la sortie.3 Le TW3882XF offre un excellent rapport axial et une variation du centre de phase \u00e9troitement group\u00e9e.<\/p>\n\n
