ʻEhā-hōkū nui-Band Survey antenna 40dBi GPS GLONASS Beidou Galileo
Hoʻolauna Huahana
ʻEhā-hōkū nui-frequency waho ho'āʻo antenna: Hiki i ka antenna ke loaʻa nā hōʻailona GPS L1/L2, GLONASS G1/G2, Beidou II B1/B2/B3, a ua kūpono me ka GALILEO E1/E5a/E5b pūnaewele frequency band.Hiki ke hoʻohana nui ʻia i ka nānā ʻana i ka geodetic, ke kūkulu ʻana i ke alahaka, ke kūkulu ʻana i ke alanui, ka ʻenehana, ka nānā ʻana i ka moana, ka ʻāina i lalo o ka wai, ka hoʻāʻo ʻana i ke alanui kula, ka hana pahu pahu a me nā manawa ʻē aʻe.He kūpono no nā ʻōnaehana ʻekolu a me ʻehā ʻōnaehana kiʻekiʻe kiʻekiʻe a me ka palapala ʻāina.·
He kiʻekiʻe ka pololei o ka antenna, haʻahaʻa haʻahaʻa, loaʻa kiʻekiʻe, loaʻa maikaʻi ma nā kihi haʻahaʻa haʻahaʻa, polarization circular ākea ākea, a me ke kikowaena pae paʻa.Hoʻohana ka ʻāpana antenna i kahi hoʻolālā hoʻolālā multi-feed e hōʻoia i ka hui ʻana o ke kikowaena phase a me ke kikowaena geometric, e hōʻemi ana i ka hopena o ka antenna i nā hewa ana a me ka hoʻomaikaʻi ʻana i ke ana pololei.Hoʻokomo ʻia i loko o ka module amplifier haʻahaʻa haʻahaʻa.
