Namuhla sizoxoxa ngalokho GPS, indlela uhlelo lusebenza. Thina ukulalelisisa ekuthuthukiseni lobu buchwepheshe, izici zalo zisebenza kahle. Sizobuye sixoxe nendima eyadlalwa amabalazwe interactive ohlelweni.
Indaba GPS
Indaba positioning zohlelo jikelele, noma izixhumanisi, waqala e-United States namanje in the 50s ezikude lapho kuqalwa isathelayithi lokuqala Soviet emkhathini. Ithimba lososayensi owayegade kwethulwa, kwazeke ukuthi ngasekupheleni satellite ibanga ngokulinganayo kushintsha imvamisa lophansi. Ngemva ngo-ejulile analysis bona idatha baye bafinyelela esiphethweni sokuthi ngosizo iziphuphutheki, uma sikhuluma kabanzi, indawo yayo kanye ibhiphu, ungakwazi ukunquma ngokunembile khona nesivinini ukunyakaza kwabantu emhlabeni, futhi aba amaSheshi, satellite velocity orbit ekunqumeni eqondile Ebantwini. Lwathi luphela ngeminyaka yoma-US zoMnyango Wezokuvikela wasungula uhlelo GPS izinjongo zabo, futhi eminyakeni embalwa kwaba iyatholakala ukuba isetshenziswe abantu abangekho empini. Uhlelo GPS ukuthi isebenza kanjani manje? Ngendlela efanayo njengoba wasebenza ngesikhathi, ku izimiso ezifanayo futhi eziyisisekelo.
inethiwekhi iziphuphutheki
Bangaphezu kuka-iziphuphutheki amabili nane emzileni sizungeze Earth, ukudlulisa amasignali esibophezelayo. Isibalo iziphuphutheki kuyahlukahluka, kodwa ukulokho njalo inombolo efanele ukuqinisekisa ekusebenzeni, plus abanye kubo in isitokwe, ukuze uma zokugwema ukuphuka wokuqala ukuthatha imisebenzi yabo ngokwabo. Njengoba ukuphila service ngamunye wabo emhlabeni iminyaka engaba ngu-10, wenza kwethulwa entsha, izinguqulo ngcono. Ukujikeleza satellite lwenzeka omise eziyisithupha emhlabeni Umhlaba endaweni engamamitha amakhilomitha engaphansi kwengama-20 eziyinkulungwane, akha khona inethiwekhi oxhumene, ukusebenzisa i-GPS esiteshini. Thola zakamuva ziqhingi ezishisayo futhi axhunyiwe iphuzu eliyinhloko ebalulekile e-United States.
Kanjani GPS-Itilosi?
Le nethiwekhi Ungafunda indawo by kuhlaziywa ukubambezeleka we isiginali kusuka kumasathalayithi, futhi ukunquma izixhumanisi ngokusebenzisa lolu lwazi. Uhlelo GPS ukuthi isebenza kanjani manje? Njenganoma iyiphi inethiwekhi navigation emkhathini - ke nakanjani free. Isebenza ne ukusebenza kahle kakhulu kuzo zonke izimo zezulu bese nganoma isiphi isikhathi sosuku. Ukuthengwa kuphela okufanele wena unaso GPS-Itilosi, noma idivayisi esekela umsebenzi GPS. Empeleni, itilosi isimiso ukusebenza kusekelwe elula navigation isikimu eside esetshenziswa: uma wazi kahle indawo lapho into umaka ukuthi kufanelekile kakhulu indima umhlahlandlela, kanye nebanga elivela yona, ukudweba indilinga lapho uphawu indawo yakho iphuzu. Uma lo engaba umbuthano likhulu ke esikhundleni salo umugqa oqondile. Chitha ambalwa bands kusuka endaweni kungenzeka ohlangothini lwakho izimpawu, iphuzu empambana emigqeni izomaka indawo yakho ebalazweni. Kumasathalayithi ngenhla kulesi simo, nje ukudlala indima letintfo umaki ibanga kusuka indawo yakho angaba yizinkulungwane 18 km. Nakuba Ukujikeleza yabo orbit bese uya ngesivinini esikhulu, indawo njalo ukugadwa. isiphequluli ngasinye efakwe GPS-umamukeli, okuyinto zahlelwa ukuba imvamisa oyifunayo, futhi ukuxhumana ngqo ne satellite. isignali ngamunye umsakazo oqukethe inani elithile ulwazi anekhodi, okubandakanya izitatimende mayelana nesimo yomsebenzi satellite, indawo yayo eMhlabeni orbit nesikhathi zone (isikhathi samanje). By the way, ulwazi mayelana nendawo nesikhathi esiqondile ezibaluleke kakhulu ukuthola idatha emayelana izixhumanisi yakho kwenzekani kubalwa ubude besikhathi phakathi umthelela kanye yokwamukela isignali yomsakazo iyanda yi ijubane amagagasi omsakazo futhi-unomphela izibalo ukubala ibanga phakathi kudivayisi yakho navigation kanye satellite orbit.
Ubunzima ukuvumelanisa
Kususelwa lesi simiso Ukuqondiswa kwemikhumbi, kuthathwa ngokuthi ukunquma ngokunembile isikhundla sakho singase sidingeke iziphuphutheki amabili nje, esekelwe amasignali ukuthi kuyoba lula ukuthola iphuzu yemigwaqo, futhi ngenxa yalokho - indawo lapho ukhona. Kodwa, ngeshwa, Ngezizathu zezobuchwepheshe ezidinga ukusetshenziswa okungaphezu kokukodwa satellite njengendlela umaka. Inkinga eyinhloko iwashi GPS-umamukeli ukuthi ayikuvumeli ukuvumelanisa esanele kumasathalayithi. Isizathu salokhu kube ukuthi ukubonisa isikhathi umehluko (kusiphequluli sakho bese emkhathini). Satellites abakhona eliphezulu okunethezeka amawashi njalo athomu, siyivumele ukuba ukubala isikhathi ngobuciko obukhulu, kuyilapho abamukelayo ezivamile amawashi anjalo akunakwenzeka ukusebenzisa, njengoba usayizi, izindleko, ukuba yinkimbinkimbi ukusebenza awuzange ungivumele ukuba uzisebenzise yonke indawo. Ngisho iphutha elincane 0,001 imizuzwana ungase ucabange ukuthi ubhekene izixhumanisi km ezingaphezu kuka-200 e-isiqondiso!
umaka wesithathu
Ngakho Onjiniyela watimisela kuya ezivamile asebenza ngebhethri ubuchwepheshe GPS-Itilosi uhambe ngenye indlela, uma sikubeka ngokuqondile - ukusebenzisa esikhundleni isiqondiso ezimbili satellite - ezintathu, ngokulandelana, inani elifanayo imigqa owela okwalandela. Isixazululo kusekelwe ophumayo Ngokuhlakanipha elula: ezimpambanweni zomgwaqo obuthathu imakwe omaka, ngisho uma ukungalungi kungenzeka, ukudala indawo esime unxantathu, maphakathi okuyinto ethatha maphakathi yayo - indawo yakho. Iphinde yembule umehluko isikhathi umamukeli bese zonke iziphuphutheki ezintathu (okuyiwona umehluko kuyafana), ukuthi ikuvumela ukulungisa empambana emigqeni ncamashi maphakathi, Ngamafuphi nje - sichaza isikhundla sakho GPS.
omunye imvamisa
Kufanele kuphawulwe ukuthi zonke iziphuphutheki ithunyelwa Imininingwane kudivayisi yakho at a imvamisa olulodwa, futhi lokhu kuyinto engavamile ngempela. Kusho GPS-Itilosi futhi kanjani walichaza kanjani lonke ulwazi ilungile, uma konke kumasathalayithi ngokuqhubekayo futhi kanyekanye ulithumele Imininingwane? Zonke lilula. Isethelayithi omoya ukucacisa isignali ngokwayo umsakazo uthunyelwa kwenye, futhi ulwazi oluvamile, okuyinto ngekhodi ikhodi. Uthi satellite izici eliphezulu futhi lilondolozwe database kudivayisi yakho, lapho ke ikuvumela ukuba uqinisekise idatha data base satellite lesiphequluli. Ngisho nalapho inqwaba iziphuphutheki limile ngokushesha futhi kalula bakwazi ukubona okungawabo. Konke lokhu lula lonke icebo, ikuvumela ukuthi usebenzise i-GPS-Itilosi ezincane futhi buthaka antenna reception, okuyinto kunciphisa tindleko kanye kunciphisa design nobungako zedivayisi.
GPS-amabalazwe
GPS amabalazwe ilandelwe idivayisi yakho eceleni, njengoba wenza ukuthonya kukhethwa indawo okuyiwona ufuna ukuhambisa. Uhlelo usetha kuphela indawo yakho emhlabeni, futhi ikhadi umsebenzi Ayenethemba kule nguqulo sokuqhafaza kwesikrini esiseceleni lapho izixhumanisi, okuyinto ikuvumela ukuba udabule sezwe. GPS njengendlela umsebenzi kuleli cala? Mahhala, ngakho futhi uhlala kuleli isimo, ikhadi kwezinye izitolo inthanethi (hhayi kuphela) Namanje ikhokhwe. Ngokuvamile, izicelo ngabanye zidalwe yedivayisi nge GPS-Itilosi ukusebenza amabalazwe: kokubili ezikhokhelwayo khulula. ikhadi ezihlukahlukene lezimanga emnandi futhi ikuvumela ukuba wenze ngendlela ofisa ngayo indlela kusuka iphuzu A kuya endaweni B njengoba ulwazi ngangokunokwenzeka kanye nazo zonke Izinsiza okuyinto ezikhangayo wena kuzodlula, enqamulelayo eya endaweni, izwi umsizi, Inkhombandlela kanye nezinye.
Engeziwe GPS-imishini
uhlelo GPS isetshenziswa hhayi kuphela ukuze abonise indlela osithandayo. Kuvumela i-surveillance into, okungase kube okuthiwa beacon noma i-GPS-Tracker. Siqukethe owamukelayo isignali futhi Transmitter ngesisekelo GSM, 3gp noma ezinye yezifiso zokuxhumana ukuze adlulisele ulwazi indawo into ezindaweni inkonzo, ngizithiba. Zisetshenziswa izimboni eziningi: ukuphepha, ezempilo, umshwalense, ezokuthutha kanye nabanye abaningi. imoto zomsebenzi futhi khona, ezixhunywe kuphela emotweni.
Ukuhamba ngaphandle kwezinkinga
Nsuku zonke ikhadi ukubaluleka kanye ikhampasi unomphela ubuyele ku esedlule. ubuchwepheshe besimanje ukuvumela umuntu iholele uhambo lwakhe nge ukulahlekelwa sakugcina isikhathi, imizamo kanye nemali, ngesikhathi esifanayo ukubona izindawo ethokozisa isimanga kanye ezithakazelisayo. Yayiyini kumnandi sekudlule cishe ikhulu leminyaka edlule manje usukhona, futhi angasebenzisa cishe njalo umbutho wezempi, amatilosi nama-pilot bezindiza izivakashi kanye ngezithunywa. Manje is kuyanda okwandisa nokusetshenziswa kwalezi izinhlelo ngokuba inzuzo, ukuzijabulisa kanye nokukhangisa izimboni, lapho wonke usomabhizinisi kungase kubonise ngokwayo kumephu global zezwe, futhi ngeke kube lula ngempela ukuthola. Sithemba ukuthi lesi sihloko kuye kwangisiza ukuba wonke umuntu onekareko, GPS - ukuthi isebenza kanjani, kungasiphi isisekelo, a ukuzimisela izixhumanisi, yini izimfanelo zayo kanye nobuthakathaka.
