Ukuqalelisa ngokungafanelekanga ikhompyutha ngokucofa kwi Umlawuli

Njengoko nezimaphambili ezingundoqo apho umsebenzi isiqalo ebandayo, sebenzisa lwencwadi kunye ephemeris. Umongo la magama kuya kuxoxwa ngezantsi. Abasebenzisi zobugcisa zale mihla umdla kancinane kweenkqubo zangaphakathi emsebenzini wayo. Yiloo nto ngaphandle kwaye Umatiloshe, leyo ngoku esisetyenziswa ngokubanzi iinjongo ezahlukeneyo ukunika ezihambelanayo ngqo.

Indlela yokusebenza yesi sixhobo elula kakhulu. Ngenxa iperi iminwe inokuba umzuzu ukuba achaze indlela elizayo. Emva kokusebenzisa isixhobo kwimizuzwana limisela ngqo yokuququzelela indawo abo banabo.

Ukuze siqonde iimpawu kwiinkalo zobugcisa ukuba lokuba olu hlobo kobuchwepheshe, ingakumbi ukuqonda ukuba ukwenza njani lokulayita kwibrawuza, akwanelanga ukuba aqhelane ulwazi olusisiseko olufunekayo ukuze zisetyenziswe. Kuyimfuneko ukuba uphanda kanye isigama kunye isakhiwo izixhobo kunye inyathelo kwicala layo ezisebenzayo.

isigama basic

Ukuze siqonde indlela isiqalo GPS ukubanda nobushushu, kufuneka baqonde isigama esisiseko. lwesigaba ngasinye yobuchwepheshe nesayensi izele ngokoMthetho. Nangona le mfihlakalo ozalanayo kuqala weva amazwi, kuhlahlelwa ixabiso kuba ingqiqo kwacaca Nakukubona.

Theory of navigation wasemajukujukwini ingqalelo:

• movement satellite;
• reception umqondiso, ukusetyenzwa, ukudluliselwa;
• signal encoding.

Njengoko kuchaziwe ngaphambili, ukuqala ashushu nabandayo luxhomekeke isigama. Makhe sihlolisise ngokweenkcukacha ingqiqo lwencwadi kunye ephemeris.

isetyenziswa njani lwencwadi yokukhangela

Njengoko igama elithi "Almanac" eziqhelekileyo kwabaninzi. Ngokuba lixesha lokuqala eli lizwi savakala esikolweni. Enyanisweni, lo lwencwadi kugqalwa uhlobo handbook eziqulathe ulwazi data amaxabiso esisiseko ngeenkwenkwezi. Le datha ifaka isigxina imizimba yasezulwini esithubeni, ingakumbi ziyabophelela iintshukumo zabo neentsuku zekhalenda. Almanac ezindala emhlabeni ithathwa ethi "Tun Isono" evela eTshayina.

Ngexesha le omkhulu abo ukuqalelisa ashushu nabandayo, akukho nto kuye kwatshintsha ukuqeshwa achaza. Utshintsho nawo kuphela data ngokwayo, okanye ngaphezulu kanye inani labo. Ngenxa uphuhliso ubuchwepheshe bale mihla kwakunye neempawu ukusebenza koomatshini ezintsonkothileyo, iinkcukacha lwencwadi ziye ebanzi ngakumbi noluchanekileyo.

Almanac ezisetyenziswa kwinkqubo satellite navigation mihla, kuyinto isethi data, kuquka ulwazi zonke Orbital iparameters eziphambili ngaphakathi apho intshukumo-Hewana system navigation.

Almanac uye Orbital parameters ezintandathu, satellites eziphantsi. Ngamnye eliya kusebenza kangangexesha elithile. satellite ngalinye nkqubo data ezinye satellites. Ngenxa yoko, Umlawuli, lokufumana indibaniselwano omnye kuphela kubo, ukulungiswa anthology "ufunda" idatha zonke ezinye ezindleleni zazo.

Xa kulayishwa lwencwadi kwimemori esasihamba, umsebenzisi akanokukwazi ukusebenzisa olu lwazi iintsuku ezingama-30. Ngaphandle koku, uhlaziyo data kwenzeka kakhulu ngakumbi rhoqo. Le nkqubo yenziwa ngexesha uxhulumaniso omnye kwizikhululo emhlabeni okhoyo imihla yonke ezimbalwa.

Okukodwa ephemeris

ukuqalelisa ukhokelwa kunye data ezifana ephemeris. Zisetyenziswa ukuba abale Orbital izinxaxhi, ukuphazamiseka kunye nezinye izinto. Ngamanye amazwi, le ephemeris kuphela ukunceda ukumisela indawo-Hewana, kodwa kwenza kube lula ukwenza oko ngokuchanileyo olukhulu.

Ezo ephemeris, ezo idatha echanekileyo, mhlawumbi ngaphandle umhla. Umsebenzi le datha kuthatha imizuzu engama-30 kuphela. Hlaziya olu lwazi kwaye lwaqhutywa yi kwizikhululo emhlabeni.

Ukubaluleka kwala idatha ukuze akwazi ukwenza ukuqalelisa eshushu okanye ebandayo kwi Umatiloshe, izicacele. receiver isikhundla zingenakuqinisekiswa ngaphandle ulwazi malunga nendawo-Hewana navigation. Oku kufuna satellites ezine.

I algorithm asetyenziswe Umatiloshe

Qonda imigaqo jikelele apho kukho lokulayita kwibhrawuza, kulula. Kodwa ukuba sithethe malunga algorithm, ngoku kwifowni yakho, ngoko ke kunokuba jikelele kuphela. ulwazi Ubunzulu idlalwa kuphela ngumkhangeli developers.

Ngokubanzi, isiphumo sale ibandakanya:

1. esasihamba Okuqukiweyo kwenza iinzame ukuba uqhagamshelane enye Hewana navigation okhoyo.
2. Isathelayithi yokuqala, leyo wakwazi ukuseka ngempumelelo uqhagamshelwano, iqala ekudluliseleni lwencwadi isixhobo. Lidla iqulethe yonke inkcazelo esisiseko malunga umlaza enye Orbital satellite ngaphakathi kwinkqubo navigation ethile.
3. Ngenxa unxibelelwano satellite mnye ukufumana uququzelelo ngqo ngokwaneleyo (wobungakanani - 4), i usindileyo kuqala ukudluliselwa ephemerides zabo. Oku nokulungiswa ukubekwa khona.

Iimpawu ikhompyutha ngokucofa iqhosha lokulayita

Xa uvula ifowuni yakho okokuqala, okanye emva kokuba ikhefu elide kwi lokulayita kubangelwa. Umsebenzisi kufuneka alinde ixesha logama nje bafumana zilungelelanise zabo. Oku kuya kuba lixesha lokulayita GPS.

Ixesha lokulinda kuxhomekeke imiba eyahlukeneyo:

• kwinqanaba umgangatho weyunithi yokunyuselwa efakwe kwi kwibhrawuza;
• zingaphi Hewana na emehlweni;
• iimpawu nemozulu;
• kwisalathiso kwengxolo magnetic, nto leyo maxa ezitsho yokusebenza.

Ngokubanzi, ikhompyutha ngokucofa iqhosha lokulayita - imeko esasihamba apho kwinkumbulo yakhe ngokubanzi akukho Ephemeris kunye Almanac. Kwezinye iimeko, idatha ukuze langoku, kodwa ziya kuqwalaselwa lixesha.

Kuba data ezintsha kuya kufuneka ukuba uqale i-GPS ikhompyutha ngokucofa iqhosha lokulayita kwaye enze zonke zazo eziyimfuneko.

amanyathelo algorithm of lokulayita

Kuba esasihamba data omtsha ufuna ukuba umjikelo opheleleyo we sesicatshulwa.

ukuqalelisa ngexesha elifanayo kuquka la manyathelo alandelayo:

• kumfuna isathelayithi yokuqala kunye iinzame ukuzama ukuqhagamshelana naye;
• abafumana lwencwadi kunye nokulondolozwa kwezi data;
• ekufumaneni nasekugcineni ephemeris;
• Kwiinzame ukuseka unxibelelwano kunye namanye Hewana abathathu;
• ukufumana iinkcukacha kwiisathelayithi ephemeris ezintathu ivenkile data;
• Sebenzisa ephemeris ukubala zilungelelanise zalo.

Ngenxa zingaphi izenzo yenziwe ukuze "warm" Umlawuli, kucacile ukuba kutheni isixhobo lokulayita kufuna ixesha.

Ngokubanzi, xa sisondela isifaniso, a sungula onjalo Umlawuli ifuze ixesha iindleko injini lokulayita.

Iimpawu ezifudumeleyo aqalise ezishushu

Hot esasihamba Qala luphawulwa phambi kwimemori lwe data ngqo - lwencwadi esebenzayo kunye ephemeris. Izenzo esele ibonwe. Ziintsuku 30 Almanac, isiqingatha seyure - phezu ephemeris.

Ukukwazi ukwenza isiqalo shushu apho kunokwenzeka ukuba amandla sele icimile ixesha elifutshane. Oku kuthetha ukuba izothola zikwazi kuncitshiswa ngokubonakalayo ngenxa nokulawula.

Idinga kuphela:

• zama ukuseka uqhagamshelwano nge yonke Hewana;
• ukuba kuyimfuneko, ukuba benze lo ephemeris uhlaziyo kunye nolondolozo zazo;
• usebenzisa ephemeris ukubala uququzelelo indawo yayo.

Xa ukuqalelisa lo msebenzi lula kakhulu. Kule meko, Umlawuli uba lwencwadi lwangoku, kodwa kufuneka ukufumana ephemeris oluhlaziweyo.

Iimpawu esasihamba "Navitel"

"Navitel" uhlobo software navigation software. Kujongwe ukuba naluphi na uhlobo izixhobo kwi izixhobo leyo equka yangaphandle okanye eyakhelwe-GPS-receiver. Le program ibonelelwa ngokulanda iimephu kumazwe awahlukeneyo kwi ifomu eneenkcukacha.

amakhadi enjalo ziqulathe:

• inqubo ye zezindlu;
• amagama ezitalato;
• amagama izikhululo metro, njalo njalo.

ukuqalelisa ngokungafanelekanga ikhompyutha ngokucofa "Navitel" lithetha ukuba bengaziwa ixesha yokusebenza, ephemeris, indawo, lwencwadi. off umbundu, apho iinkcukacha yokukhangela ilahlekileyo, kuba iiyure ezingama-70 okanye ngaphezulu. Oku negalelo navigation kunye nokuthuthwa phezu imigama emide off. Inkqubo yokufumana data kulo mzekelo sele kuchaziwe ngaphambili. ixesha ukuqalelisa unokuthatha kwemizuzu engama-20.

Abaqhubi abaninzi zizithengele iimoto ikhithi yawo ibe lokulayita Webasto. Ngapha koko, injini imoto yakhe ngamaxesha yokungasebenzi ngexesha lonyaka abandayo kufuneka ubushushu nje, ngokunjalo navigation.

Ukuba sithethe malunga ukuqalelisa nobushushu Umlawuli "Navitel", kufanele kuqatshelwe ukuba beesekethe iyafana isenzo. Kuphela ekuqaleni isixhobo ubushushu luvuliwe emva kwemizuzwana embalwa. Xa zika ezishushu ebalwa elingaphantsi komzuzu.

Izinto eziluncedo "Navitel" esasihamba

Kukho iinkqubo ezininzi ezifanayo. Kodwa xa kuthelekiswa kubo "Navitel" ineendlela ezininzi.

Izinto eziluncedo idivayisi:

• zoom fast and pan imaphu, inkqubo;
• inkqubo usuke ezenzekelayo;
• akhetha orientation neemephu isekelwe kwi indlela apho ukuhamba okanye ngokwesiseko indawo ngasentla;
• ulwazi ziqhele fullscreen;
• 2D no-3D iindlela;
• Umsebenzi izixhobo zootshuphe.

kwicala isixhobo esebenzayo ixhasa imisebenzi emininzi, kuquka ukumiselwa indawo yangoku emephini, ukubonisa oko, yomgudu (manual okanye automatic), njl
