L’antenne h\u00e9lico\u00efdale \u00e0 profil bas HC990XF eXtended-filter, en instance de brevet, est con\u00e7ue pour le positionnement de pr\u00e9cision, couvrant les bandes de fr\u00e9quences GPS\/QZSS-L1\/L2\/L5, QZSS-L6, GLONASS-G1\/G2\/G3, Galileo-E1\/E5a\/E5b\/E6, BeiDou-B1\/B2\/B2a\/B3, et NavIC-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.<\/p>\n\n

L’antenne HC990XF supporte la technologie XF (eXtended Filtering) de Tallysman. \u00c0 l’\u00e9chelle mondiale, le spectre des fr\u00e9quences radio est devenu encombr\u00e9 par l’activation de nombreuses nouvelles bandes LTE, dont les signaux ou les fr\u00e9quences harmoniques peuvent affecter les antennes et les r\u00e9cepteurs GNSS. En Am\u00e9rique du Nord, le service Ligado pr\u00e9vu, qui \u00e9mettra dans la gamme de fr\u00e9quences de 1526 \u00e0 1536 MHz, peut affecter les signaux GNSS. De m\u00eame, les nouveaux signaux LTE en Europe [Band 32 (1452 \u2013 1496 MHz)] et au Japon [Bands 11 and 21 (1476 \u2013 1511 MHz)] ont \u00e9galement affect\u00e9 les signaux GNSS. La technologie XF de Tallysman att\u00e9nue tous ces signaux.<\/p>\n\n
