ʻO nā hōkū he nui i ka antenna RTK GNSS
Hoʻolauna Huahana
Aia ma lalo o nā hiʻohiʻona ka hōkū holo piha holoʻokoʻa satellite navigation antenna:
liʻiliʻi liʻiliʻi,
kūlana kiʻekiʻe-pololei,
Loaʻa kiʻekiʻe,
ikaika anti-interference hiki.
ʻO ka hoʻolālā antenna me ka multi-feed no laila paʻa ke kikowaena phase.I ka manawa like, ua lako pū ka antenna me kahi pā choke multi-path, kahi e pale pono ai i ka mana o ka hoʻopili ʻana i ka hōʻailona ma ka pololei o ka hoʻokele ʻana ma ke kāohi ʻana i nā hōʻailona multi-ala.
Hiki i ka hoʻolālā anti-surge ke kū'ē maikaʻi i ka hoʻopilikia o waho a hōʻoia i ka paʻa a me ka palekana o nā hōʻailona hoʻokele.
Eia kekahi, ʻo kēia antenna ka laulā o nā hiʻohiʻona noi.Inā he geodetic surveying, oceanographic surveying, waterway surveying, a i ʻole ka nānā ʻana i ke ōlaʻi, ke kūkulu ʻana i ke alahaka, ka hili ʻāina, ka hana pahu pahu, a me nā mea ʻē aʻe, hiki iā ia ke lawe i nā lawelawe hoʻokele pololei a maikaʻi i nā ʻano āpau o ke ola.
