L’antenne h\u00e9lico\u00efdale brevet\u00e9e HC871SXF est con\u00e7ue pour le positionnement de pr\u00e9cision, couvrant les bandes de fr\u00e9quences 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

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. Le spectre des fr\u00e9quences radio est devenu plus encombr\u00e9 \u00e0 mesure que de nouvelles bandes LTE sont activ\u00e9es et leurs signaux ou fr\u00e9quences harmoniques [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 peuvent avoir un impact particulier sur les antennes GNSS qui prennent en charge les services de correction de la bande L bas\u00e9s dans l’espace (1539 – 1559 MHz). Les nouveaux signaux LTE en Europe [Band 32 (1452 – 1496 MHz)] et au Japon [Bands 11 and 21 (1476 \u2013 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
