Pocket geolocation yog ib qho zoo sib xws thiab paub tsis ntev los no. Tam sim no txhua tus qauv ntawm cov xov tooj niaj hnub muaj GPS system. Tab sis feem ntau cov neeg siv muaj lus nug txog nws. Piv txwv li, lawv xav paub yuav ua li cas txhawm rau txhim kho GPS txais tos ntawm Android lossis IOS kom tau txais cov ntaub ntawv qhov chaw raug ntau dua lossis ua si ua si uas xav tau cov ncauj lus kom ntxaws geolocation yooj yim dua. Cia peb tsom xam qhov teeb meem no thiab nrhiav seb yuav ua li cas.
Y GPS yog dab tsi?
GPS yog ib qho system uas tso cai rau koj lub xov tooj smartphone siv cov apps navigation thiab txiav txim siab koj qhov chaw los muab txoj hauv kev zoo tshaj plaws rau koj qhov chaw. Raws li tau txais cov ntaub ntawv los ntawm satellites nyob rau sab nraud.
Vim li cas kuv thiaj xav tau?
GPS navigation yog siv los ntawm kev siv navigation. Ua ke lawv pab kom mus rau qhov chaw zoo yam tsis muaj kev kawm ntxaws txog daim ntawv qhia chaw ntawm thaj chaw thiab xaiv lwm tus ntawm lub ntsiab lus "Yuav mus qhov twg ntxiv thiab tig qhov twg?"
Tus nto moo tshaj plaws GPS navigators rau Android: Yandex. Maps lossis Yandex. Navigator, GoogleMaps thiab MapsMe. Koj tuaj yeem nrhiav tau pirated version ntawm Navitel hauv Is Taws Nem. Tab sis qhov kev zov me nyuam yuav yog xyoo tso tawm qub. Nyob rau hauv rooj plaub no, nws muaj peev xwm coj koj mus rau txoj kev uas tsis muaj nyob thiab nyob rau hauv "cib". Tsis tas li ntawd, qhov kev zov me nyuam yuav kis tau tus kab mob. Tom qab ntawd muaj qhov ua tau tias nws yuav "lov" lub kaw lus ntawm koj lub xov tooj smartphone, thiab koj yuav tau hloov tsis yog tus navigator xwb, tab sis kuj yog lub xov tooj lossis tsawg kawg nws cov firmware.
Tam sim no cov qauv xov tooj ntau tshaj plaws thiab niaj hnub no yog IOS-raws li IPhone thiab cov xov tooj txhawb nqa sib txawv ("Android"). Lawv siv GPS hauv daim ntawv tshaj lij - A-GPS. Qhov no yog ib qho kev ua haujlwm uas ua rau kom nrawm ntawm daim ntawv thov thaum lub caij txias thiab kub pib, vim muaj lwm yam kev sib txuas lus (WI-FI, cellular), thiab tseem txhim kho qhov chaw raug.
Cold start - qhov xwm txheej uas lub xov tooj tsis tuaj yeem txuas rau cov satellites tshiab thaum daim ntawv thov qhib. Nyob rau hauv cov ntaub ntawv no, nws ua hauj lwm autonomously raws li cov ntaub ntawv kis tau tus mob nyob rau hauv lub dhau los switch-on los ntawm cov satellites uas nws tau txuas nrog. Kub pib - thaum lub satellites tam sim ntawd suav nrog hauv kev ua haujlwm. Lawv tshwm sim ntawm daim ntawv thov screen lossis hauv ib lub tab tshwj xeeb rau kev taug qab lawv txoj haujlwm thiab tau txais cov ntaub ntawv.
thawj qhov kev txhim kho kev xaiv
Muaj ntau txoj hauv kev los txhim kho GPS txais tos ntawm Android lossis IOS. Cia wb mus saib 3 lub npe nrov tshaj plaws. Ua ntejthiab txoj hauv kev yooj yim tshaj plaws los txhawb lub teeb liab GPS yog qhib hom tsim nyog hauv xov tooj. Txhawm rau ua qhov no, ua cov kauj ruam hauv qab no:
- Tig rau GPS (geolocation) thiab mus rau hauv xov tooj.
- Nrhiav qhov "Geodata" ntu.
- Xaiv lub pob saum toj "Mode".
- Qhib lub qhov rai hu ua "Kev Tshawb Nrhiav".
- Xaiv cov khoom "High raug".
Koj lub xov tooj kev ua tau zoo yuav txhim kho los ntawm kev qhib qhov tseeb. Nyob rau tib lub sijhawm, nws lub sijhawm ua haujlwm yam tsis tau them rov qab tuaj yeem txo ntau zaus. Qhov tshaj plaws yog tias tus navigator suav nrog yuav tsuas "noj" lub roj teeb.
Txoj kev thib ob los txhim kho GPS txais tos ntawm Android
Qhov kev xaiv thib ob yog qhov nyuaj dua. Tab sis nws pab ntau npaum li thawj zaug. Koj yuav tsum rub tawm ib qho app kom tshem cov ntaub ntawv GPS. Tom qab hloov kho cov ntaub ntawv satellite, cov txheej txheem navigation yuav ua haujlwm zoo dua qub. Tab sis qhov kev xaiv no yuav tsis haum rau qee lub xov tooj vim app thiab qauv tsis sib xws, tsis muaj chaw, thiab lwm yam.
Txoj kev nyuaj tshaj plaws tab sis txhim khu kev qha
Nws yog qhov thib peb, kev daws teeb meem nyuaj tshaj plaws, yuav ua li cas txhim kho GPS txais tos ntawm Android. Nws yog tsim nyog rau computer geniuses. Nws lub ntsiab lus yog nyob rau hauv kev hloov pauv ntawm cov ntaub ntawv kaw lus uas tswj kev ua haujlwm ntawm lub xov tooj GPS system. Cia peb txheeb nws raws li kev txiav txim:
- Nws yog qhov yuav tsum tau rho tawm cov ntaub ntawv GPS. CONF nyob hauv daim nplaub tshevsystem/etc/gps/conf, los ntawm cov kev pabcuam tshwj xeeb uas muab kev nkag mus rau cov ntaub ntawv kaw lus. Tom qab ntawd peb txav nws mus rau lub cim xeeb sab hauv ntawm lub xov tooj lossis mus rau SD daim npav kom nws tuaj yeem qhib rau lub khoos phis tawj yav tom ntej.
- Hloov lub GPS. CONF nqis yog ua tiav los ntawm Notepad ++ program ntawm lub PC tsis tu ncua. Thiab lub xov tooj txuas nrog lub computer ntawm tus qauv USB cable.
- Tom ntej no, koj yuav tsum hloov cov chaw ntawm NTP server, uas yog siv rau lub sijhawm synchronization. Feem ntau lawv hais tej yam zoo li no - North-america.pool.ntp.org. Qhov kev nkag yuav tsum tau sau dua tshiab - ru.pool.ntp.org lossis europe.pool.ntp.org. Yog li ntawd, nws yuav tsum tig tawm zoo li no: NTP_SERVER=ru.pool.ntp.org.
- Tsis tas li ntawd, nws yuav tsis yog superfluous nkag mus rau cov servers ntxiv yam tsis tau hloov pauv rau lawv: XTRA_SERVER_1=https://xtra1.gpsonextra.net/xtra.bin, XTRA_SERVER_2=https://xtra2.gpsonextra.net /xtra.bin, XTRA_SERVER_3=https://xtra3.gpsonextra.net/xtra.bin.
- Tom ntej no, koj yuav tsum txiav txim siab seb tus neeg txais GPS puas yuav siv WI-FI los txhawb lub teeb liab. Thaum nkag mus rau ENABLE_WIPER=parameter, koj yuav tsum sau tus lej uas yuav tso cai (1) lossis txwv tsis pub (0) siv kev sib txuas wireless. Piv txwv li, ENABLE_WIPER=1.
- Qhov kev ntsuas tom ntej yog kev sib txuas ceev thiab cov ntaub ntawv raug. Nyob ntawd, koj xaiv yog: INTERMEDIATE_POS=0 <-- (muaj tseeb, tab sis qeeb) lossis INTERMEDIATE_POS=1 <-- (tsis yog, tab sis nrawm).
- Nyob rau hauv hom kev hloov ntaub ntawv siv, cov neeg txawj ntse qhia txog kev teeb tsa Tus Neeg Siv Dav Hlau, uas yog lub luag haujlwm rau kev hloov pauv ntawm cov ntaub ntawv rau cov neeg siv dav dav. Ces nyob rau hauv txoj kab kev pab cuam nws yog sauDEFAULT_USER_PLANE=TRUE.
- Qhov tseeb ntawm GPS cov ntaub ntawv yog saib xyuas los ntawm INTERMEDIATE_POS=qhov ntsuas, nyob rau hauv kab uas koj tuaj yeem teeb tsa ob qho tib si rau hauv tus account tag nrho cov ntaub ntawv yam tsis muaj kev zam, thiab tshem tawm qhov yuam kev. Yog tias koj muab 0 (zero) tom qab "=" kos npe, geolocation yuav coj mus rau hauv tus account txhua yam nws pom, thiab yog tias nws yog 100, 300, 1000, 5000, nws yuav tshem tawm qhov yuam kev. Programmers pom zoo kom teeb nws rau 0. Tab sis yog tias koj xav sim, koj tuaj yeem siv kev debugging.
- Daim ntawv thov ntawm A-GPS muaj nuj nqi, raws li tau hais los saum toj no, tau txais kev txhawb nqa lossis qhib rau txhua yam khoom siv niaj hnub no. Tab sis yog tias koj tseem xav kom txoj haujlwm ua haujlwm raws nraim, ces koj yuav tsum teeb DEFAULT_AGPS_ENABLE=TRUE hauv A-GPS pab kab.
- Qhov kawg ntawm cov ntaub ntawv yuav tsum tau khaws cia thiab rub tawm rau hauv lub xov tooj, tom qab ntawd rov pib dua.
Ib qho tseem ceeb: yog tias koj tsis xav ua txhua yam ntawm koj tus kheej rau ntau yam, piv txwv li, vim kev tub nkeeg, ntshai ua txhaum ib yam dab tsi hauv lub kaw lus, thiab lwm yam, ces koj tuaj yeem nrhiav cov ntaub ntawv GPS. CONF nrog cov kev txwv uas koj xav tau thiab tsuas yog luam rau koj lub smartphone. Nws tsuas yog rov pib dua lub xov tooj thiab siv GPS txhim kho.
Vim li cas GPS tsis ua haujlwm ntawm Android tseem?
Muaj lwm yam teeb meem. Nws tshwm sim tias GPS tsis ua haujlwm ntawm Android txhua (nws tsis qhib, nws tsis nrhiav satellites, thiab lwm yam). Rov pib dua lub kaw lus rau lub Hoobkas teeb tsa tuaj yeem pab daws qhov teeb meem no. Qhov no ua tiav los ntawm kev teeb tsa hauv xov tooj. Tsis tas li ntawd, lub gadget tuaj yeem hloov kho lossis muab tso tsegCov neeg ua haujlwm pabcuam hauv chaw pabcuam uas yuav "txiav" rau hauv cov khoom siv hluav taws xob thiab kho qhov tsis xws luag.
