Chitani Chidwi Passive GPS Antennas
Ndondomeko Yogwiritsira Ntchito Padziko Lonse (GPS) zimayenda pozilandira zizindikiro kuchokera ku satellites, ndipo izi sizingatheke popanda mtundu wina wa antenna. Chifukwa chake nthawi zambiri simukuwona chizindikiro chilichonse cha nyenyezi pamene mukuyang'ana galimoto ndilo mwa iwo ali ndi ziphuphu zomwe ziri zobisika mkati, kapena zimangidwira mkati, vuto.
Kuwonjezera pa zida zomangidwa, zida zambiri za GPS zimakhalanso ndi mwayi wogwiritsa ntchito antenna yakunja. Ngakhale sizingakhale zofunikira kukhazikitsa ma GPS antenna, pali zochitika zomwe zingathandize.
Ndani Amafunikira Antenna ya GPS?
Ngati mwakhala mukugwiritsa ntchito galimoto kwa kanthawi, ndipo simunazindikirepo kutayika kapena chizindikiro choyenera, ndiye simukusowa mtundu uliwonse wa antenna. Chokhachokha ndichokha ngati mukukonzekera kuyendetsa kwinakwake inu simunayambe mwakhalapo kale, ndiye kuti mkhalidwe wosiyana mu malo atsopano ungapangitse antenna kufunikira.
Ngati, ngati, mwakhala mukukumana ndi zinthu monga ngati chiwonetsero chakutayika kapena kusamveka bwino ndi gawo la GPS, ndiye mwayi ndi wabwino kuti GPS yangwiro ya antenna ikhoza kukhala yoyenera mtengo wogula.
Zimakhudzadi zinthu ziwiri: khalidwe la antenna limene GPS yanu imabwera nayo ndi zoletsera zomwe mukuzichita.
Zina zomwe zingakhalepo zimaphatikizapo kusintha kuchokera ku galasi lapadera la GPS kupita ku dash-in-unit , kapena kugula chipangizo chatsopano cha GPS nthawi yoyamba. Milandu ngati iyi, ikhoza kulipira kuti afunse ngati wina aliyense m'dera lanu ali ndi zizindikiro kapena zolondola ndi magulu awo GPS asanayambe kupanga ndalama.
Zotsatira za Zoletsedwa ndi Kusamvana pa Kulandidwa kwa GPS
Zida zoyendetsa GPS zimagwira ntchito pozilandira zizindikiro kuchokera ku makina a satellites omwe ali mbali ya Global Positioning System. Pogwiritsa ntchito malangizo ndi kuwonetsa mphamvu za ma satellites ambiri, kachipangizo ka GPS kamatha kuwerengera bwinobwino malo ake enieni ndi pang'ono.
Pamene chipangizo cha GPS sichikuwoneka bwino chifukwa cha kutsekemera, sichikhoza kupeza zizindikiro zokwanira za satana, zomwe zingachititse kuti zonse zisawonongeke. Izi zikhoza kuyambitsidwa ndi zinthu ngati nyumba zazitali, koma madenga (ndipo nthawi zambiri mawindo) a magalimoto ndi magalimoto amapanganso zolepheretsa zomwe zingasokoneze mphamvu ya chizindikiro cha GPS.
Zotsatira za zoletsedwa zingathe kuchepetsedwa poika malo a GPS pazenera, koma magalimoto ena ndi ovuta kuthana ndi ena. Mwachitsanzo, denga lamatabwa limapanga zowonjezera zowonjezera RF kuposa zida za ragtops, ndipo mawindo osindikizira angaphatikizepo tinthu ting'onoting'ono tazitsulo zomwe zingalepheretse chizindikiro cha GPS.
Mkati Antennas yangwiro ya GPS
Zida zambiri zogwiritsa ntchito GPS zimabwera ndi ziwalo zamkati zomwe zimagwira ntchito bwino ngati zikuwonetsedwa momveka bwino.
Komabe, ziphuphu zamkatizi zimakhala zochepa kwambiri kuposa zikopa zazikulu zakunja, zomwe zingakhale zopanda mphamvu kapena zowonjezereka. Pankhani ya ziphuphu zakunja zowonjezera, mphamvu yamagetsi ya GPS ikhoza kuwirikiza kawiri poyerekeza ndi antenna yopanda mphamvu.
Ngati mutapeza kuti GPS yanu nthawi zina imalephera kupeza chizindikiro, kapena ngati imawoneka yosagwirizana nthawi zina, ndiye kuti phokoso lakunja limatha kuthetsa vuto. Ziri zotsika mtengo komanso zosavuta kuyesa kusuntha chipangizo chozungulira mozungulira m'galimoto yanu yoyamba, popeza izi zingathandize kuthetsa vutoli komanso zosokoneza, koma mungapeze kuti njira yokhayo yothetsera vutoli ndi kukhazikitsa zowonjezera.
Passive Vs. Amplified GPS Antennas
Antennas akunja a GPS akhoza kukhala osalimbikitsa kapena owonjezera. Zizindikiro zopanda mphamvu zimangolandira chizindikiro cha GPS ndikuzipereka ku chipangizo cha GPS, pamene magulu opangira ntchito akuphatikizapo amplifier yomwe imapangitsa mphamvu ya chizindikiro.
Zomalizazo zimakhala zodula komanso zovuta kuziyika, koma zimatha kukhazikitsidwa kutali kwambiri ndi GPS yanu kusiyana ndi momwe mungagwiritsire ntchito antenna. Kawirikawiri, phokoso lokhazikika liyenera kukhazikitsidwa popanda makina ochepa kwambiri a coaxial pakati pake ndi GPS.
Popeza kuti ma antine amatha kuikidwa patali, amatha kugwiritsa ntchito magalimoto akuluakulu.
