Ikhasi eligcinwe ngesinye isibukezo in the Navigator

Njengoba imiqondo eyisisekelo lapho umsebenzi isiqalo ezibandayo, sebenzisa lwencwadi futhi ephemeris. Ingqikithi migomo kuzoxoxwa ngezansi. Abasebenzisi ubuchwepheshe besimanje isithakazelo kancane izinqubo zangaphakathi emsebenzini wayo. Kuyinto ayihlukile neze futhi itilosi, okuyinto manje kabanzi isetshenziselwe izinhloso ezinhlobonhlobo ukunikeza izixhumanisi ngqo.

Lo mshini wezenzo zale divayisi silula. Ngenxa pair of umunwe ukunyakaza kungaba iminithi akhombisa izinkomba esizayo. Ngemva ukushintsha kudivayisi ngemizuzwana inquma ngqo Ukudidiyela indawo umnini wayo.

Ukuze siqonde izici izici lobuchwepheshe ukuthi esivela kule uhlobo lobuchwephese, futhi ikakhulukazi ukuba baqonde indlela yokwenza ukuqalisa ikhompiyutha kusiphequluli, akwanele ukuba bajwayelane ulwazi oluyisisekelo oludingekayo ukuze kusetshenziswe. Kuyadingeka ukuba umbe ujule kakhulu amagama kanye nokwakheka apharathasi begodu isenzo uhlangothi lwalo sokusebenza.

amagama Eziyisisekelo

Ukuze uqonde ukuthi amakhaza kanye hot isiqalo GPS, kufanele baqonde amagama ayisisekelo. sphere Ngamunye kwezobuchwepheshe nesayensi ugcwele imigomo. Naphezu imfihlakalo isihlobo waqale wezwa amazwi, kudluliswa ukubaluleka kuba umqondo ngempela ecacile futhi bayezwa.

Theory isikhala navigation ezibhekwa:

• ukunyakaza satellite;
• isignali reception, ukucubungula, ukudluliswa;
• amasignali wekhodi.

Njengoba kushiwo ngaphambili, ekuqaleni ashisayo nabandayo incike amagama. Ake sihlole kabanzi umqondo lwencwadi futhi ephemeris.

Indlela isetshenziswa navigation lwencwadi

Nge elithi "lwencwadi" ijwayelekile eziningi. Ngokokuqala ngqá leli gama kwakuzwakala esikoleni. Eqinisweni, lwencwadi kubhekwa uhlobo bhukulwazi eliqukethe eziyisisekelo ulwazi idatha amanani ezinto ezisemkhathini. Le datha ihlanganisa isikhundla nezinto zasemkhathini emkhathini, ngokucacile of zibopha ukunyakaza kwabo ezinsukwini zekhalenda. lwencwadi endala kakhulu emhlabeni kubhekwa incwadi "Tun Sin" ovela eChina.

Ngesikhathi amatilosi abanale isiqalo ashisayo nabandayo, akukho okushintshile ekukhetfweni ezincwadini zonyaka ezazisakazeka. Izinguquko zabhekana kuphela idatha uqobo, noma ngaphezulu ngokunembile inombolo yabo. Banikezwe ukuthuthukiswa ubuchwepheshe yesimanje kanye izici ukusebenza imishini eyinkimbinkimbi, idatha lwencwadi babé ebanzi xaxa futhi kunembile.

Lwencwadi elisetshenziswa yesimanje satellite navigation system, kuyinto iqoqo idatha, kuhlanganise ulwazi lonke nemingcele esemqoka esemkhathini ngaphakathi ukunyakaza satellites navigation system.

Lwencwadi unamapharamitha eziyisithupha esemkhathini, iziphuphutheki ephethwe. Ngamunye okuyinto isebenza isikhathi esithile. Ngamunye satellite kohlelo inedatha yezinye iziphuphutheki. Ngenxa yalokho, itilosi, esungula uxhumano munye, ukulungiswa Anthology "ifunda" idatha mayelana zonke ezinye zazo zingaphazami.

Lapho kulayishwa lwencwadi kwimemori itilosi, umsebenzisi bangasebenzisa lolu lwazi izinsuku ezingu-30. Naphezu kwalokhu, buyekeza idatha kwenzeka kakhulu njalo. Le nqubo ibizwa eyenziwa ngesikhathi ngokuqondene omunye iziteshi ezikhona phansi njalo ngemva kwezinsuku ezimbalwa.

ngokucacile ephemeris

ikhasi eligcinwe ngesinye isibukezo uqondiswa nedatha ezifana ephemeris. Zisetshenziswa ukubala esemkhathini ngeziphambeko, isiphithiphithi uphazamise nezimoto nezinye izinto. Ngamanye amazwi, lo ephemeris hhayi kuphela ukusiza ukunquma indawo iziphuphutheki, kodwa futhi enze kube nokwenzeka ukuba sikwenze ngokunemba okukhulu.

Labo ephemeris, okuyizinto idatha olunembile kunazo, okungenzeka kakhulu ukuthi iphelelwe yisikhathi. Umsebenzi walo idatha kuthatha imizuzu engu-30 kuphela. Buyekeza lolu lwazi futhi eyenziwa iziteshi phansi.

Ukubaluleka kwalezi idatha ukuze senze isiqalo kushisa noma kubanda e itilosi, kusobala. umamukeli isikhundla ayikwazi ukucaciswa ngaphandle ulwazi mayelana indawo navigation iziphuphutheki. Lokhu kudinga iziphuphutheki ezine.

I-algorithm esetshenziswa itilosi

Qonda imigomo ejwayelekile lapho kukhona ukuqalisa ikhompiyutha kusiphequluli, kulula. Kodwa uma sikhuluma algorithm, wamanje kule divayisi, khona-ke kungaba jikelele. Ukujula ulwazi kungenziwa kuphela ezijatshulelwa isiphequluli onjiniyela.

Ngokuvamile, umphumela kule divayisi zihlanganisa:

1. Itilosi Kufaka kwenza imizamo yokuxhumana omunye navigation iziphuphutheki ekhona.
2. I isathelayithi lokuqala, okuyinto wakwazi ngempumelelo usungule uxhumano, iqala okuxhunyanwa kudivayisi lwencwadi. It ngokuvamile iqukethe lonke ulwazi oluyisisekelo mayelana eyodwa esemkhathini satellite umlaza ngaphakathi ethile navigation system.
3. Ngoba ukukhulumisana nomunye satellite ukuthola izixhumanisi eqondile ngokwanele (ubuningi ubuncane - 4), asele uqale ukudluliselwa ephemerides yabo. It kuzoba intuthuko ukubekwa yabo.

Izici ukuqalisa

Lapho ushintshela kudivayisi yakho okokuqala noma ngemuva kwekhefu elide ku ukuqalisa ikhompiyutha kucushwa. Umsebenzisi kudingeka alinde isikhashana nje wathola izixhumanisi zabo. Lokhu kuyoba ngesikhathi abandayo isiqalo GPS.

Isikhathi sokulinda kuxhomeke ezicini eziningana:

• ezingeni izinga ukwamukelwa iyunithi ukufakwa isiphequluli;
• indlela iziphuphutheki abaningi emehlweni;
• izici weatherproof;
• phezu Inkomba umsindo kagesi, elisemnyango yokusebenza amaza.

Ngokuvamile, ukuqalisa - isimo Itilosi lapho inkumbulo yakhe ngokuvamile ayinakho Ephemeris futhi lwencwadi. Kwezinye izimo, le datha khona, kodwa ngeke kubhekwe ukuthi ayisebenzi.

Ukuze idatha entsha kuyodingeka uqale GPS ukuqalisa futhi enze yonke manipulations kunesidingo.

Algorithm izinyathelo ukuqalisa ikhompiyutha

Ukuze entsha Itilosi idatha kudinga umjikelezo ogcwele ukudlula.

ikhasi eligcinwe ngesinye isibukezo ngesikhathi esifanayo kuhlanganisa izinyathelo ezilandelayo:

• cinga leli isathelayithi lokuqala kanye umzamo ngixhumane naye;
• ethola lwencwadi kanye nokulondolozwa lezi idatha;
• ukuthola nokubuyisa ephemeris;
• ngomzamo ukusungula yokukhulumisana nabanye iziphuphutheki ezintathu;
• enikwa ezintathu iziphuphutheki ephemeris kanye nokugcina idatha;
• Sebenzisa ephemeris ukubala izixhumanisi lalo.

Njengoba sazi ukuthi abaningi izenzo kwenziwe ukuze "kulungele" itilosi, kuyacaca ukuthi kungani idivayisi ukuqalisa ikhompiyutha kudinga isikhathi.

Ngokuvamile, uma sithola isifaniso, lokwethulwa enjalo Navigator sifana nesikhathi izindleko injini abandayo isiqalo.

Izici efudumele futhi siqala esishisayo

Hot Qala Itilosi libhekene khona kwimemori idatha langempela - lwencwadi asebenzayo futhi ephemeris. Izenzo wawabona. Kuyinto izinsuku ezingu-30 e-lwencwadi, isigamu sehora - kwi ephemeris.

Ikhono ukwenza isiqalo ashisayo lapho kwenzeka ukuthi amandla kuvaliwe okwesikhathi esifitshane. Lokhu kusho ukuthi i-algorithm ngeke unike amandla kakhulu ziyancipha okwesikhathi Ukudidiyela.

Idinga kuphela:

• zama usungule uxhumano yonke iziphuphutheki;
• uma kunesidingo, ukuze uhambise ephemeris update kanye nokongiwa zabo;
• usebenzisa ephemeris ukubala izixhumanisi indawo yayo siqu.

Lapho isiqalo esijabulisayo umsebenzi lula kakhulu. Kuleli zinga, itilosi has a lwencwadi zamanje, kodwa kudingeka uthole ephemeris zohlelo.

Izici Itilosi "Navitel"

"Navitel" uhlobo software navigation. Kuhloswe noma luphi uhlobo amadivayisi imishini ehlanganisa sangaphandle noma i-GPS eyakhelwe-umamukeli. Lolu hlelo olunikezwa ukulanda amabalazwe amazwe ehlukene ifomu enemininingwane.

amakhadi okunjalo aqukethe:

• izinombolo zezindlu;
• amagama emigwaqo;
• amagama iziteshi kaMasipala nokunye.

ikhasi eligcinwe ngesinye isibukezo "Navitel" lisikisela ukuthi engaziwa Yizinga isikhathi, ephemeris, isikhundla, lwencwadi. ukuvala nombundu, lapho idatha navigation kulahleka, ngema-awa lange-70 noma ngaphezulu. Lokhu kungaba nomthelela navigation kanye zokuthutha olude off. Inqubo yokuthola idatha kuleli cala isivele echazwe ngaphambilini. Cold sokuqala ingahlala imizuzu engaphezu kwengu-20.

Abashayeli abaningi ukuthenga izimoto zabo kit isiqalo ezibandayo Webasto. Phela, injini yemoto ngezikhathi sokungasebenzi phakathi nenkathi ebandayo nje idinga Ukushisa, kanye navigation.

Uma sikhuluma isiqalo efudumele futhi kushisa Navigator "Navitel", kufanele kuphawulwe ukuthi wesifunda iyafana isenzo. Kuphela ekuqaleni zedivayisi ukushisa icushiwe emva kwamaminithi ambalwa. Lapho izixhumanisi ashisayo ebalwa ngaphansi komzuzu.

Izinzuzo "Navitel" Itilosi

Kukhona izinhlelo eziningi ezifanayo. Kodwa uma kuqhathaniswa nabo "Navitel" kunezinzuzo eziningi.

Izinzuzo kudivayisi:

• zoom kuyashesha futhi pan ibalazwe, uhlelo;
• inqubo usuke ngemishini;
• kukhethwa orientation amamephu esekelwe isiqondiso lapho ukunyakaza noma ngesisekelo indawo enyakatho;
• Imininingwane bezibona yesikrini esigcwele;
• 2D ne-3D izindlela;
• Umsebenzi tooltips.

Functional kudivayisi ohlangothini isekela izici eziningi, kuhlanganise ukuzimisela isikhundla lamanje kumephu, sibonise ke, yomgudu (ibhukwana noma othomathikhi), njll
