I-GPS Yenza Umsebenzi Wendawo Yomsebenzi, kodwa Iza Ngokukhathazeka Ngokwemfihlo
I-iPhone yakho ifaka phakathi i-chip ye-GPS njengaleyo etholakala kumadivayisi we-GPS azimele. I-iPhone isebenzisa i-chip chip ngokubambisana nemibhoshongo yeselula namanethiwekhi we-Wi-Fi-inqubo ebizwa ngokuthi "i- GPS esiziwe" -ukubala ngokushesha isikhundla sefoni. Awudingi ukusetha i-chip ye-GPS, kodwa ungayivala noma uyivumele ngokukhetha i-iPhone.
I-GPS Chip
I-GPS isifinyelele ohlelweni lwe- Global Positioning System , okuyinto yokwakhiwa kwe-satellite constellation kanye nokwesekwa kwengqalasizinda efakwe futhi igcinwe nguMnyango Wezokuvikela wase-US. I-GPS ithola isikhundla ngokudonswa okungenani kwezintathu zomakhalekhukhwini ezingu-31 ezingenzeka. Amanye amazwe asebenza ezinkambisweni zawo, kodwa uhlelo lwe-US kuphela olusetshenziswa kabanzi emhlabeni jikelele. Uhlelo olulodwa kuphela olusondeleyo uhlelo lwe-satellite ye-GLOSNASS yeRussia. I-iPhone ikwazi ukufinyelela kokubili i-GPS nezinhlelo ze-GLOSNASS.
Ubuthakathaka obunye be-GPS ukuthi isibonakaliso saso sinenkinga yokungena kwezakhiwo, izinkuni ezijulile kanye nama-canyons, kuhlanganise namademoni asezindaweni zasemadolobheni asezindaweni zasemadolobheni, okuyilapho izigodlo zesitokisi nama-Wi-Fi izimpawu zenza i-iPhone ibe inzuzo ngaphezu kwama-GPS e-stand-alone.
Ukuphatha ulwazi lwe-GPS
Nakuba ukuxhumana kwe-GPS okusebenzayo kubalulekile ekuhambeni nasekusebenzeni imephu, phakathi kwamanye amaningi, kukhona ukukhathazeka kwangasese okuhlobene nokusetshenziswa kwayo. Ngenxa yalesi sizathu, i-iPhone iqukethe izindawo eziningana lapho ungalawula khona nokuthi uma ngabe amandla e-GPS asetshenziswa kanjani efonini.
Ukulawula i-GPS ku-iPhone
Ungavala ubuchwepheshe bendawo ku-iPhone-okuyinto i-Apple ayinconywa-ngokuya kuzilungiselelo > Ubumfihlo nokuguqula amasevisi wendawo . Kunokuba wenze lokho, bheka uhlu olude lwezinhlelo zokusebenza kusikrini sezinsizakalo zendawo lapha ngezansi "Yabelana Ngendawo Yami." Ungasetha ngayinye ku-Never, ngenkathi usebenzisa noma njalo. Iphuzu liwukuthi, uthatha ukulawula ukuthi yiziphi izinhlelo zokusebenza ezisebenzisa idatha yakho yendawo nokuthi kanjani.
Ukufinyelela kuhlu lohlelo lokusebenza
Thepha isithonjana sezilungiselelo bese upheqa phansi ohlwini lohlelo lokusebenza. Lapho ungathinta isithonjana ngasinye sohlelo lokusebenza esibonisiwe ukuze ubone ukuthi sisebenzelana kanjani ne-GPS (lapho kufanele khona) kanye nefoni yakho. Ungashintsha noma uvale izilungiselelo ezihlukahlukene, kuye ngohlelo lokusebenza, kufaka phakathi indawo, izaziso, sebenzisa idatha yeselula nokufinyelela kukhalenda yakho noma oxhumana nabo nokuningi.
GPS Complementary Technologies
I-iPhone inezinkinobho eziningana ezihambisanayo ebhodini ezisebenza ngokubambisana ne-GPS chip ukuthola indawo yocingo.
- I-Accelerometer ne-Gyroscope: I-iPhone ine-gyroscope encane encane engama-6-axis kanye ne-accelerometer inhlanganisela chip ebhodini. I-gyroscope isitshela ukuthi ifoni yakho iqondiswe kanjani ngaso sonke isikhathi. I-accelerometer ithola futhi ibhale imibiko emikhulu nangamancane njengemigomo engayisebenzisa ifoni.
- Ukulandelela kwe-Wi-Fi: Uma i-GPS ingasebenzi kahle, njengezakhiwo zangaphakathi noma ezakhiweni ezide, ukulandelela kwe-Wi-Fi kungayithatha noma kuyifake esikhundleni. I-Wi-Fi yokulandelela isebenzisa imininingwane yamanethiwekhi e-Wi-Fi emhlabeni jikelele ukuze i-triangulate isikhundla sefoni ngokusekelwe kumasignali amaningi we-Wi-Fi.
- I-Compass: I-iPhone yakho inekhampasi yedijithali njengengxenye ye-chip yayo yokulandela ukuhamba. Ikhampasi isetshenziselwa ukwengeza ezinye ubuchwepheshe bokuhamba futhi ukuqondisa noma yiliphi ibalazwe ozisebenzisayo. Ikhampasi iqala ukudlala, isibonelo, uma uthepha umcibisholo we-Maps ukuqondisa imephu. I-Compass ingasetshenziswa futhi yedwa.
- I-Barometer: Ungase ucabange nge-barometer, elinganisa ukucindezela komoya, njengokwedlulele idivayisi yokubikezela isimo sezulu, kodwa ayisetshenziselwa leyo njongo ku-iPhone. I-barometer ihlanganisa i-GPS chip yokulinganisa izinguquko zokuphakama ukudala ukufundwa okunembile nokuphakanyiswa kokuphakama.
- I-M10 Motion Coprocessor: Ku-iPhone, i-Apple isebenzisa i-M10 motion coprocessor chip ukuze ilandele idatha ngokuqhubekayo kusuka ku-accelerometer, ikhampasi, i-gyroscope, ne-barometer. Lokhu kukhululeka umsebenzi kusukela ku-A10 Fusion chip ukuze kube namandla okuthuthukisa amandla.
