L’antenne h\u00e9lico\u00efdale brevet\u00e9e HC977SXF est con\u00e7ue pour le positionnement de pr\u00e9cision, couvrant les bandes de fr\u00e9quences GPS\/QZSS-L1\/L2\/L5, GLONASS-G1\/G2\/G3, Galileo-E1\/E5a\/E5b, BeiDou-B1\/B2b\/B2a, et NavIC-L5, y compris le syst\u00e8me d’augmentation par satellite (SBAS) disponible dans la r\u00e9gion d’op\u00e9ration [WAAS (Am\u00e9rique du Nord), EGNOS (Europe), MSAS (Japon), ou GAGAN (Inde)], ainsi que les services de correction de la bande L.<\/p>\n\n

Pesant seulement 32 g, le HC977SXF, l\u00e9ger et compact, est dot\u00e9 de l’\u00e9l\u00e9ment h\u00e9lico\u00efdal de pr\u00e9cision Tallysman de deuxi\u00e8me g\u00e9n\u00e9ration qui offre d’excellents rapports axiaux et fonctionne sans plan de masse, ce qui le rend id\u00e9al pour une grande vari\u00e9t\u00e9 d’applications, y compris les v\u00e9hicules a\u00e9riens sans pilote (UAV). L’\u00e9l\u00e9ment h\u00e9lico\u00efdal miniaturis\u00e9 de deuxi\u00e8me g\u00e9n\u00e9ration est environ 25 % plus l\u00e9ger et 20 % (1 cm) plus court que l’\u00e9l\u00e9ment h\u00e9lico\u00efdal de premi\u00e8re g\u00e9n\u00e9ration, sans compromis sur les performances telles que le gain maximal au z\u00e9nith, la faible d\u00e9croissance et la largeur de bande.<\/p>\n\n

Le HC977SXF 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. Le filtrage \u00e9tendu a \u00e9t\u00e9 ajout\u00e9 \u00e0 l’antenne HC977 pour att\u00e9nuer les nouvelles bandes de fr\u00e9quences radio qui interf\u00e8rent avec les signaux GNSS. Par exemple, de nouvelles bandes LTE ont \u00e9t\u00e9 activ\u00e9es et leurs signaux ou fr\u00e9quences harmoniques peuvent affecter les antennes et 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 antennes GNSS qui re\u00e7oivent les signaux du service de correction en bande L bas\u00e9 dans l’espace (1539 – 1559 MHz). De m\u00eame, les nouveaux signaux LTE en Europe [Band 32 (1452 – 1496 MHz)] et au Japon [Bands 11 and 21 (1476 \u2013 1511 MHz)] ont \u00e9galement affect\u00e9 les signaux GNSS. Enfin, la liaison montante de communication par satellite Inmarsat (1626,5 – 1660,5 MHz), couramment utilis\u00e9e sur les navires, peut \u00e9galement affecter les antennes GNSS situ\u00e9es \u00e0 proximit\u00e9.<\/p>\n\n

Les essais sur le terrain ont confirm\u00e9 que la technologie XF personnalis\u00e9e de Calian att\u00e9nue les nouveaux signaux (Europe et Japon) et les signaux LTE existants, ce qui permet \u00e0 l’antenne XF de produire des donn\u00e9es de radiofr\u00e9quence GNSS propres et pures.<\/p>\n\n

Les \u00e9l\u00e9ments d’antenne h\u00e9lico\u00efdale log\u00e9s de deuxi\u00e8me g\u00e9n\u00e9ration de Calian sont prot\u00e9g\u00e9s par un robuste bo\u00eetier en plastique IP67 de qualit\u00e9 militaire. La base du bo\u00eetier comporte deux inserts filet\u00e9s pour une fixation s\u00fbre, ainsi qu’un joint torique en caoutchouc autour du bord ext\u00e9rieur pour assurer l’\u00e9tanch\u00e9it\u00e9 de la base de l’antenne et de son connecteur SMA m\u00e2le int\u00e9gr\u00e9.<\/p>\n\n
