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 prend en charge la technologie eXtended Filtering (XF) de Tallysman. \u00c0 l’\u00e9chelle mondiale, le spectre des radiofr\u00e9quences est d\u00e9sormais satur\u00e9 en raison de l’activation de nombreuses nouvelles bandes LTE, dont les signaux ou les fr\u00e9quences harmoniques peuvent perturber les antennes et les r\u00e9cepteurs GNSS. En Am\u00e9rique du Nord, le service Ligado pr\u00e9vu, qui \u00e9mettra dans la bande de fr\u00e9quences comprise entre 1 526 et 1 536 MHz, peut perturber les signaux GNSS. De m\u00eame, les nouveaux signaux LTE en Europe [bande 32 (1 452 \u2013 1 496 MHz)] et au Japon [bandes 11 et 21 (1 476 \u2013 1 511 MHz)] ont \u00e9galement perturb\u00e9 les signaux GNSS. La technologie XF de Tallysman att\u00e9nue l\u2019impact de tous ces signaux. <\/p>\n\n
