Le TW3997 est une antenne Accutenna\u00ae pleine bande \u00e0 r\u00e9glage pr\u00e9cis qui offre une couverture compl\u00e8te des syst\u00e8mes GPS\/QZSS-L1\/L2\/L5\/L6, GLONASS-G1\/G2\/G3, Galileo-E1\/E5a\/E5b\/E6, BeiDou-B1\/B2\/B2a\/B3, NavIC-L5, L5, y compris le syst\u00e8me de renforcement satellitaire (SBAS) disponible dans la r\u00e9gion d’exploitation [WAAS (Am\u00e9rique du Nord), EGNOS (Europe), MSAS (Japon) ou GAGAN (Inde)], ainsi que les services de correction en bande L. Il est sp\u00e9cialement con\u00e7u pour un positionnement GNSS pr\u00e9cis en bande compl\u00e8te. <\/p>\n\n

Le TW3997 est dot\u00e9 d’un \u00e9l\u00e9ment de patch superpos\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. L’antenne dispose \u00e9galement d’un pr\u00e9-filtre puissant pour att\u00e9nuer les interf\u00e9rences des signaux intermodul\u00e9s provenant de la LTE et d’autres bandes cellulaires. Le TW3997 offre un excellent rapport axial et une variation du centre de phase \u00e9troitement group\u00e9e.<\/p>\n\n

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 TW3997 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

L’OEM TW3997 est fourni avec un plan de masse circulaire standard de 60 mm de diam\u00e8tre, avec un c\u00e2ble coaxial termin\u00e9 par un connecteur (l’angle droit MCX est illustr\u00e9 dans le dessin). Des trous de montage sont pr\u00e9vus pour la fixation sur des plans de masse plus importants. Des options de r\u00e9glage personnalis\u00e9 et de plan de masse peuvent \u00eatre disponibles, en fonction du niveau d’engagement d’achat.<\/p>\n\n

Ce produit est \u00e9galement disponible en format log\u00e9 : TW3990XF<\/a>.<\/p>\n\n
