Ingxaki enje ngonyaka ka-2000 iya kuchaphazela amawaka eGPS kwihlabathi liphela kule mpelaveki ngenxa yomda okhoyo kwiisistim ukusukela oko kwadalwa inkqubo yokumisa yehlabathi. Yimpazamo esele yenzekile ngo-1.999, kwaye izakuvela kwakhona kule mpelaveki ngesizathu esinye esilula: imathematika.
Ukusetha kwakhona inombolo yeveki kwi-GPS
Xa ngowe-1980 owokuqala IGPS, abavelisi baphoqeleka ukuba basebenzise inkqubo ye-10-bit ngenxa yokunciphisa imemori eyayikho ngelo xesha. Olu kukhubazeka luchaphazela ngokuthe ngqo indlela inkqubo ekwazi ngayo ukubala imihla, ekubeni izibalo ziya kuvumela kuphela ukuba ihlanganise ixesha elilinganiselweyo leeveki ezili-1024 (iminyaka eyi-19,7). Ithetha ntoni le nto? Ewe, xa idlula elo xesha, inkqubo ihlala ikwi-limbo. Okanye kunoko, buyela ekuqaleni. Yinto eyaziwa ngokuba yi- Inombolo yeVeki yoMnyhadala we-Rollover.
Ngobusuku buka-Agasti 21-22, 1999 yenzeka, kwaye kule mpelaveki kuya kwenzeka into efanayo kwakhona. Kodwa kwenzeka ntoni kanye kanye? Ukuba isixokelelwano siyasebenza ngexesha lokusetwa kwakhona komhla, umsebenzi usenokubuyisela iimpazamo ngoko nangoko kwaye ukukhangela kuya kulahleka. Ukuba uzama ukusebenzisa iyunithi ngosuku olulandelayo, indawo inokusebenza kakuhle, kodwa ukubala kwe-ETA kuya kubuyela amaxabiso angenangqondo ngokupheleleyo. Nangona eyona nto iqhelekileyo kukuba akunakwenzeka ukuseka uxhumano kunye neesathelayithi, njl. Oko kukuthi, i-GPS iya kuyeka ukusebenza ngokuchanekileyo.
Kodwa iimeko ezimbi kakhulu aziyi kufunyanwa kukhangelo lomntu. Iisistim ze-GPS zisetyenziselwa ukwenza i-geolocate kwaye ichaze izinto eziguquguqukayo zeenkqubo ezininzi ezintsonkothileyo, ngoko ke impazamo ekugcinweni kwayo kwiinkqubo ezibalulekileyo inokubangela iingxaki ezinkulu. Ukukunika umbono, izikhululo zamandla zinokunxibelelana enye kwenye kwaye zilungelelaniswe ngoncedo lweenkqubo zeGPS. Ukuba eli xesha, ukusebenza kunokuba yingozi.
Ungazi njani ukuba iGPS yam ichatshazelwa yingxaki yokusetha kwakhona inombolo yeveki?
Ukuba unesixhobo seGPS esiyilelweyo ukusuka ngo-2010, uqhubo lwakho lukhuselekile kakhulu kule ngxaki. Isizathu asikho esinye ngaphandle kokusetyenziswa kwenkcazo ye-IS-GPS-200E, inguqulo ekhutshwe ngoJuni 2010 eyalungisa ingxaki yokubala umhla. Nangona kunjalo, ezinye iimodeli ezindala zinokuba ngaphandle kwesi satifikethi esitsha, kwaye kulapho kuvela khona iingxaki.
Esona sisombululo silungileyo kukuqhagamshelana nomvelisi weGPS kwaye ujonge ukuba iyunithi yakho ihlaziywe ngepatch yamva nje ekhoyo. Oku kufuneka kulungise zonke iingxaki. Iindaba ezimbi ziya kuba kwezo zithuthi zineenkqubo zokukhangela ezindala, kuba kuya kuba nzima (ukuba akunakwenzeka) ukuba umenzi anike inkxaso kwingxaki ethethiweyo.
Kwimeko ibha, umenzi wenze iwebhusayithi ikwazi ukufaka inombolo yesiriyali yeGPS yakho kwaye ikwazise ukuba ufuna ukwenza uhlaziyo lwesoftware ukulungisa ingxaki. Ukukhuphela kusimahla kwaye kufuneka ukwazi ukuyifaka ngaphandle kweengxaki kwimizuzu embalwa.
Jonga ukuba isixhobo sakho sokujonga iTomTom sichaphazelekile
Renault Ngenxalenye yayo, iphinde yapapasha iwebhusayithi apho ibonisa iinkqubo ezichaphazelekayo (i-R-Link Evolution kunye neCarminat Tomtom) kwaye incoma ukuhlaziywa ngaphambi kwe-6 ka-Apreli ukuphepha iingxaki.
Khangela ukuba inkqubo yakho yeRenault ichaphazelekile
