Vs Active I-GPS ye-Antennas
I-Global Positioning System (GPS) iinkqubo zokuhamba zisebenza ngokufumana iimpawu ezisuka kuma-satellites, kwaye akunakwenzeka ngaphandle kolunye uhlobo lwe-antenna. Isizathu sokuba awubonanga nayiphi na impawu ye-antenna xa ukhangela i-GPS iyunithi zazo zi-antenna ezifihliweyo ngaphakathi, okanye zakhiwe ngqo, kwimeko.
Ukongeza kwii-antenna ezakhiweyo, ezininzi izixhobo ze-GPS zinokhetho lokusebenzisa i-antenna yangaphandle. Nangona ngokuqhelekileyo akufuneki ukuba ufake i-antenna yangaphandle ye-GPS, kukho imeko apho kunokukunceda.
Ngubani ofuna i-GPS Antenne?
Ukuba uye wasebenzisa i-GPS iyunithi kwithuba elithile, kwaye awuzange uqaphele nayiphi na impazamo yokulahlekelwa okanye ukuchaneka kwemiba, mhlawumbi awudingi naluphi uhlobo lwe-antenna yangaphandle. Ukwahlukana nje kuphela ukuba uceba ukuqhubela kwindawo apho ungakaze ube khona ngaphambili, apho imeko eyahlukileyo kwindawo ekhoyo ingenza i-antenna iyimfuneko.
Ukuba, ngakolunye uhlangothi, uye wabhekana nemiba efana nokulahleka kwempawu okanye ukuchaneka okungafanelekanga ngeyunithi yeGPS, ngoko ke amathuba amnandi ukuba i-antenna ye-GPS yangaphandle ingafanelekile intengo yokuthenga.
Oku kunene kwizinto ezimbini: umgangatho we-antenna yangaphakathi apho i-GPS yakho iyunithi kunye neziphazamiso ezithile ozijongene nazo.
Ezinye iimeko ezibandakanyekayo ziquka ukutshintshwa kwiyunithi ephathekayo yeGPS ukuya kwiyunithi ye-in-dash , okanye ukuthenga isixhobo esitsha seGPS okokuqala. Kwiimeko ezinjengalezi, inokuhlawula ukubuza malunga nokuba ubani kuloo ndawo uye waba neengqinisiso okanye iinkcukacha zokuchaneka ngeeyunithi zabo zeGPS ngaphambi kokwenza utyalo-mali.
Iimiphumo zeZimiselo kunye nokuchithwa kwi-GPS Ukufumana
Izixhobo zokuhamba nge-GPS zisebenza ngokufumana iimpawu ezisuka kwinethiwekhi yeetetelliti eziyinxalenye ye-Global Positioning System. Ngokuthatha isalathiso kunye namandla ombonakaliso kwi-satellites ezininzi kwi-akhawunti, idivayisi ye-GPS inokwazi ukubala imeko yayo yesimo kunye nomda omncinane wephutha.
Xa idivaysi yeGPS engabonakali kakuhle esibhakabhakeni ngenxa yokuphazamiseka, kungenzeka ukuba ayikwazi ukufumana izibonakaliso ezaneleyo ze-satellite, ezinokubangela ukuba kukho ukungaphumeleli ngokupheleleyo ukusetyenziswa okanye ukuchaneka ngokuchanekileyo. Oku kungabangela izinto ezinjengezakhiwo ezide, kodwa uphahla (kunye neefestile rhoqo) zeemoto kunye namaloli zidala ukuphazamiseka okunokuhlaziya amandla esignali se-GPS.
Imiphumo yesithintelo iyakuncitshiswa ngokubeka indawo ye-GPS efestile, kodwa ezinye izithuthi zinzima ukujongana nabanye. Ngokomzekelo, uphahla lwentsimbi ludala ngaphezulu kwe-RF ukhuseleko kunezixhobo zokugqithisa, kwaye iifestile ezifakwe kwiintsimbi zingabandakanya iincinci ezincinci zentsimbi ezikhusela uphawu lweGPS.
Vs. zangaphakathi I-Antennas yangaphandle ye-GPS
Uninzi lwezixhobo zokuhamba ze-GPS ziza kunye nama-antenna angaphakathi asebenza kakuhle xa eboniswe ngombono ocacileyo, ongabonakaliyo esibhakabhakeni.
Nangona kunjalo, ezi zi-antenna zangaphakathi zikwazi ukukwazi ukuzenza ezincinci kunezikhuni zangaphandle, ezingabonakaliyo okanye zikhutshwe. Kwimeko yokuphucula i-antenna yangaphandle, amandla esignali se-GPS angaphinda aphindwe kabini ngokubhekiselele kwi-antenna engaphenduliyo.
Ukuba ufumanisa ukuba ngezinye iinkcukacha i-GPS iyunithi yehluleka ukufumana isalathisi, okanye ukuba ibonakala ingalungile maxa wambi, i-antenna yangaphandle iya kulungisa ingxaki. Kubiza kwaye kulula ukuzama ukuhambisa iyunithi ejikelezayo kwimoto yakho kuqala, kuba oko kunokuncedisa ukunciphisa imiqobo kunye nokuphazamiseka kwemiba, kodwa unokufumana ukuba isisombululo esifanelekileyo kuphela ukufaka i-antenna yangaphandle.
Valiyo Vs. Amplified GPS Antennas
I-antenna ze-GPS zangaphandle zingabonakali okanye ziphuculwe. Ama-antennas angapheliyo athola isalathisi se-GPS kwaye adlulisele kwidivaysi yokuhamba ye-GPS, ngelixa iiyunithi ezisebenzayo zibandakanya umbane onamandla okhuthaza amandla esignali.
Olu hlobo lokugqibela luya kubiza kwaye lunzima ukufaka, kodwa luyakwazi ukufakela kude ngakumbi kwi-unit yakho ye-GPS kunokuba i-antenna engenziwanga. Kwiimeko ezininzi, i-antenna engabonakaliyo kufuneka ifakwe ngaphandle kweetrafa ezintathu ze-coaxial cable phakathi kwayo kunye ne-GPS unit.
Ekubeni i-antenna esebenzayo ingafakelwa kude kakhulu, ikulungele ukusetyenziswa kunye neenqwelo ezinkulu.
