Koj lub iPhone suav nrog GPS nti zoo li qhov pom hauv cov khoom siv GPS nyob ib leeg. Lub iPhone siv GPS nti ua ke nrog cov xov tooj ntawm tes thiab Wi-nkaus tes hauj lwm hauv cov txheej txheem hu ua GPS pab, uas pab xam lub xov tooj txoj haujlwm. Koj tsis tas yuav teeb tsa GPS nti, tab sis koj tuaj yeem tua nws lossis txwv nws txoj haujlwm ntawm iPhone. Nov yog li cas.
Yuav ua li cas tua txhua GPS / Chaw Pabcuam
Koj tuaj yeem kaw txhua qhov chaw pabcuam, suav nrog GPS, ntawm iPhone. Nov yog li cas:
- Qhib Settings ntawm iPhone.
- In the Settings ntawv qhia, xaiv Privacy.
- Xaiv Qhov Chaw Pabcuam nyob rau sab saum toj ntawm Privacy npo.
- Caws lub Chaw Pabcuam toggle hloov nws mus rau Off/dawb txoj haujlwm.
-
Xaiv Turn Off hauv qhov kev lees paub uas tshwm sim.

txwv GPS kom tsuas yog qee qhov Apps
Koj tuaj yeem siv txoj hauv kev tshwj xeeb los ntawm kev txwv lossis tso cai nkag mus rau GPS cov ntaub ntawv rau cov apps tshwj xeeb. Koj tuaj yeem teeb tsa thaum lub app tso cai nkag mus rau GPS cov ntaub ntawv thiab lwm qhov chaw thev naus laus zis rau Tsis txhob , Nug Lub Sijhawm Ntxiv , Thaum siv lub App, los yog Ib txwm
- Go to Settings > Privacy > Chaw Pabcuam rov qab mus rau Chaw Pabcuam chaw tshuaj ntsuam.
- Txhob mus Qhov Chaw Pabcuam toggle mus rau On/ntsuab txoj haujlwm yog tias nws raug tua.
- Scroll cia rau hauv daim ntawv teev cov apps ntawm iPhone thiab xaiv ib qho.
-
Xaiv Tsis muaj, Nug Lub Sijhawm Ntxiv, Thaum siv App, lossisIb txwm txhawm rau tswj GPS thiab lwm qhov chaw siv thev naus laus zis rau lub app ntawd.
Image - Rov ua cov txheej txheem nrog txhua lub app ntawm daim ntawv teev npe.
txwv GPS rau Kev Pabcuam
Apps tsis yog tib yam ntawm iPhone uas siv GPS thev naus laus zis. Apple System Services kuj siv qhov chaw siv tshuab. Tej zaum koj yuav xav kaw qhov chaw raws li Apple tshaj tawm, piv txwv li, tab sis qhib koj qhov chaw rau kev hu xovtooj xwm ceev thiab SOS cov kev pabcuam.
txhawm rau nrhiav qhov chaw no:
- Go to Settings > Privacy > Chaw Pabcuam rov qab mus rau Chaw Pabcuam chaw tshuaj ntsuam.
- Scroll rau hauv qab ntawm lub vijtsam thiab coj mus rhaub System Services.
-
Coj mus rhaub lub toggle ntawm ib sab ntawm txhua qhov kev pabcuam txhawm rau qhib lossis kaw qhov chaw pabcuam, suav nrog GPS, rau qhov kev pabcuam ntawd.

Koj tuaj yeem pom tus xub nyob ib sab ntawm ib lossis ntau qhov Kev Pabcuam System.
- Ib xub grey qhia tias qhov kev pabcuam siv koj qhov chaw nyob hauv 24 teev dhau los.
- Tus xub liab liab txhais tau tias qhov kev pabcuam siv koj qhov chaw tsis ntev los no.
- Ib xub khoob qhia tias yam khoom nws nyob ib sab tuaj yeem tau txais koj qhov chaw nyob hauv qee zaus.
GPS Systems
GPS luv luv rau Lub Ntiaj Teb Txoj Haujlwm Txoj Haujlwm, uas yog lub kaw lus ntawm satellites muab tso rau hauv lub voj voog thiab tswj hwm los ntawm US Department of Defense. GPS pom ib txoj hauj lwm los ntawm trilateration uas siv tsawg kawg yog peb ntawm 31 satellite teeb liab.
Lwm lub teb chaws tau tsim cov tshuab, tab sis GPS tsuas yog siv dav thoob ntiaj teb. Tsuas yog lwm qhov system uas nyob ze ntawm lub peev xwm yog Russia lub GLONASS satellite system. Lub iPhone muaj peev xwm nkag tau ob qho tib si GPS thiab GLONASS systems.
Ib qho tsis muaj zog ntawm GPS yog tias nws lub teeb liab muaj teeb meem nkag mus rau hauv tsev, hav zoov sib sib zog nqus, thiab canyons, suav nrog hauv nroog skyscraper canyons. Hauv cov xwm txheej no, cov xov tooj ntawm tes thiab Wi-nkaus teeb liab muab lub iPhone kom zoo dua li ib leeg GPS units.
kab hauv qab
Txawm hais tias muaj kev sib txuas nrog GPS yog qhov tseem ceeb rau cov apps uas muaj kev taw qhia thiab kev ua haujlwm, muaj kev txhawj xeeb txog kev ceev ntiag tug ntsig txog nws siv. Vim li no, iPhone muaj ntau qhov chaw uas koj tuaj yeem tswj tau li cas thiab seb lub peev xwm GPS puas siv ntawm lub xov tooj smartphone.
GPS Complementary Technologies
Lub iPhone suav nrog ntau lub thev naus laus zis ntxiv uas ua haujlwm nrog GPS nti los tswj lub xov tooj qhov chaw.
- Accelerometer thiab gyroscope: Lub iPhone muaj me me rau-axis gyroscope thiab accelerometer ua ke nti. Lub gyroscope taug qab txoj kev taw qhia ntawm lub xov tooj, xws li seb nws tau tuav ncaj los yog ntawm nws sab. Lub accelerometer kuaj pom thiab sau cov lus tsa suab hauv xov tooj, loj thiab me, raws li cov ntaub ntawv xov tooj thiab cov apps siv tau.
- Wi-Fi taug qab: Thaum GPS tsis ua haujlwm zoo, xws li hauv cov tsev lossis hauv cov tsev siab, Wi-Fi taug qab hloov lossis ntxiv nws. Wi-Fi taug qab siv cov ntaub ntawv ntawm Wi-Fi tes hauj lwm thoob ntiaj teb los triangulate lub xov tooj txoj hauj lwm raws li ntau lub teeb liab Wi-Fi.
- Compass: Lub iPhone muaj lub xov tooj digital uas yog ib feem ntawm nws cov lus taw qhia. Lub compass ntxiv rau lwm yam kev siv thev naus laus zis thiab cov duab qhia chaw hauv xov tooj.
- Barometer: Tej zaum koj yuav xav tias lub ntsuas ntsuas, uas ntsuas huab cua siab, feem ntau yog cov cuab yeej ntsuas huab cua, tab sis nws tsis siv rau lub hom phiaj ntawm iPhone. Lub barometer pab txhawb GPS nti thiab ntsuas qhov siab hloov pauv kom tsim tau qhov siab thiab nce siab-hloov nyeem ntawv.
- M-series motion coprocessor: Lub iPhone siv Apple's motion coprocessor nti los ntsuas cov ntaub ntawv tsis tu ncua los ntawm accelerometer, compass, gyroscope, thiab barometer. Lub coprocessor offloads ua hauj lwm los ntawm lub ntsiab ua nti rau kev txhim kho zog efficiency.
