He pai te whakarite a te antena i te pokapū o te pokapū o te 1575.42mHz ± 3 MHz hei whakarite i te tino tohu tohu. Ko te VSWR he 1.5: 1 me te hōkaiipurangi he ± 5 MHz, ko te whakarite i te hononga me te hono ki nga satelites GPS. Ko te 50-Ohm i kaha ake te whakarei ake i te tuku tohu.
Ko te antena e ahu mai ana i runga i te rererangi 7x7CM whenua me te nui o te pikinga o te 3dbic. E whakarato ana i te kapinga nui, hei whakarite i te painga iti o te -9DBIC i te -90 ° me te + 90 ° me te hipoki neke atu i te 75% o te rōrahi taputapu. Ko te porization he kaupapa porowhita-tika (RHCP), e pai ana ki nga tohu tohu mai i nga amiollites i nga ahunga katoa.
Ko te LNA / tātari te whakakii i te antena Dielectric ki te whakapai ake i nga mahi. Me te 28db o te whiwhinga (kaore he taura) me te iti o te 1.5db haruru ahua, ka whakanuia nga tohu GPS ngoikore me te whakaiti i te maarama me te tika.
Ko te LNA / Tātari he tohu-kounga nui hei whakaiti i te wawaotanga o waho-o-roopu. He iti noa iho te 7DB mo te nekehanga i F0 +/ 20mHz, he iti rawa te 20DB i te F0 +/- 50MHz, me te 30DB nui o te Whakatupato i F0 +/- 100mHz. Ma tenei ka whakarite i te tohu GPS maamaa me te kounga nui, ara i nga taiao whanui me te waatea.
Ko te VSWrd o te LNA / Tātari he iti iho i te 2.0, e kii ana i te ngaro o te utu iti ki te whakanui i te kaha whakawhiti tohu me te whakaiti i te tohu tohu.
