ʻIke: Ke hoʻonohonoho ʻana i ka pilina wikiwiki
Noi: Mīkini hele manawa
Hōʻike ʻikepili:M8N
Laina huahana: GPS
Nā mea koʻikoʻi o ka huahana:
■ Panana hui
■ E nana pono i ka oihana hoomalu lele, me kona mea kakau magnetic
■ Nui huahana :25 x 25x 8 mm
■ Mea hoʻonui hōʻailona LNA i kūkulu ʻia
■ ʻOihana maʻamau 25x 25x 4mm kiʻekiʻe sensitivity ceramic antenna
■ ʻO ke aniani TCXO i kūkulu ʻia a me ka capacitor Farad no ka hoʻomaka wela ʻoi aku ka wikiwiki
■ 1-10Hz Hoʻonohonoho ʻana i ka helu hou
1. Hōʻike huahana
ʻO F23-U kahi mea hoʻokipa Beidou / GPS hiki ke loaʻa nā hōʻailona ukali me nā kaha 72, ka hoʻohana haʻahaʻa haʻahaʻa a me ka naʻau kiʻekiʻe, a hiki ke huli wikiwiki a pololei i nā hōʻailona nāwaliwali ma nā kūlanakauhale, nā canyons, nā wahi kiʻekiʻe a me nā wahi ʻē aʻe. Hele mai ka mea hoʻokipa me kahi mea kākau geomagnetic, e kōkua ana i ka mea hoʻohana e holomua i ka hana me ka wikiwiki.
