I-antenna ye-dielectric inemininingwane enhle kakhulu yemvamisa yesikhungo sika-1575.42mhz ± 3 MHZ ukuqinisekisa ukwamukelwa okulungile kwesiginali. I-VSWR ingu-1.5: 1 kanye ne-bandwidth yi- ± 5 mhz, eqinisekisa ukuxhumana okuzinzile futhi okusebenzayo nama-satellite we-GPS. Ukuphazamiseka okungu-50-Ohm kuthuthukisa ukuhanjiswa kwesiginali.
I-antenna isuselwa endizeni ye-7x7cm emhlabathini futhi inenzuzo ephezulu ye-3DBIC. Inikeza ukumbozwa okuhle kakhulu, iqinisekisa inzuzo encane ye--4dbic at -4dbic at -90 ° no-90 ° angeles, isembozo ezingaphezu kwama-75% wevolumu yedivayisi. I-polarization ine-polarization eyindilinga yesandla sokudla (i-RHCP), ethuthukisa ukwamukelwa kwesiginali kuma-satellites kuzo zonke izinkomba.
I-LNA / Isihlungi igcwalisa i-antenna ye-dielectric ukuze ithuthukise ukusebenza. Nge-28db ye-Gain (ngaphandle kwekhebula) kanye nesibalo somsindo esiphansi esingu-1.5DB, kukhulisa amasiginali we-GPS abuthakathaka futhi kunciphisa ukuphazamiseka komsindo, ngaleyo ndlela kuthuthukise ukucaciswa kokucacisa nokunemba.
I-LNA / Ihlunga futhi libonisa izihlungi ezisezingeni eliphakeme ukunciphisa ukuphazamiseka okungaphandle kwe-band. Inikeza ubuncane be-7DB ye-attenuation ku-F0 +/- 20mhz, ubuncane be-20DB ku-F0 +/- 50MHz, ne-30DB ehlaba umxhwele ye-attenuation ku-F0 +/- 100mhz. Lokhu kuqinisekisa isiginali ye-GPS ecacile nesezingeni eliphakeme, ngisho nasezindaweni ezinabantu abaningi nasenomsindo.
I-VSWR ye-LNA / Filter ingaphansi kuka-2.0, okuqinisekisa ukulahleka okuphansi kokubuyisa ukukhulisa ukusebenza kahle kwesiginali futhi kuncishise i-attiation yesiginali.
