Namhlanje siza kuthetha ntoni na GPS, esebenza ngayo le nkqubo. Sinikela ingqalelo kuphuhliso obu bugcisa, iimpawu zayo ezisebenzayo. Kwakhona siza kuxubusha indima edlalwa iimephu inxaxheba kule nkqubo.
Indaba GPS
Ibali inkqubo yokumisa equka konke, okanye uququzelelo, yaqala eUnited States ngxi 50 ezikude xa bekuqalwa isathelayithi yokuqala yiSoviet emajukujukwini. Iqela izazinzulu US wayegcine lokwazisa, waphawula ukuba le satellite kumgama iyatshintsha ngokulungelelana amaza uphawu. Emva olunzulu uhlalutyo ukuba data baye bafikelela kwisigqibo sokuba ngoncedo-Hewana, xa sithetha ngokweenkcukacha, indawo yayo kwaye beep, unako ukugqiba ngokuchanileyo ubukho kunye nesantya ukuhamba kwabantu emhlabeni, and vice versa, Velocity satellite kunye okuwo ekumiseleni the ngqo imvelaphi yabantu. Ekupheleni yoma Wase lindulule inkqubo GPS ngeenjongo zabo, yaye kwiminyaka embalwa yaba zifumaneke ukuze zisetyenziswe emkhosini. Inkqubo GPS ukuba isebenza njani ngoku? Ngendlela efanayo njengoko wayesebenza ngelo xesha, phezu kwalaa migaqo nalaa kwiziseko.
inethiwekhi-Hewana
Ngaphezu ezingamashumi amabini anesine Hewana ukujikeleza Emhlabeni, ukudlulisa imiyalezo abophe. Inani Hewana buyahluka, kodwa okuwo usoloko inani ilungelo ukuqinisekisa ukusebenza egudileyo, kunye abanye babo baye kwistokhwe, ukuze xa breakage okokuqala ukuba athathe imisebenzi yabo ngokwabo. Ekubeni ubomi inkonzo nganye kuzo macala iminyaka emalunga ne-10, wenza bekusungulwa, iinguqulelo ezintsha ziphuculwe. Njengokujikeleza yesathelayithi lwenzeka kwi nokujikeleza ezintandathu ejikeleza uMhlaba kwintaba ephakame engaphantsi kwe-20 ophosa, yenza womnatha ezihambelanayo, baleka station GPS. Fumana i zakutshanje kwiziqithi yimvula eziyelelene ingongoma ephambili yinqontsonqa eUnited States.
wenza njani GPS-esasihamba?
Lo womnatha banokufunda indawo yokubala nokubambezeleka uphawu ukusuka Hewana, yaye ukuba ukujonga zilungelelanise usebenzisa olu lwazi. Inkqubo GPS ukuba isebenza njani ngoku? Njengalo naluphi womnatha yeNavigeyishini kwisithuba - kuba ngokuphelele free. Isebenza ngempumelelo eziphakamileyo kuzo zonke iimeko zemozulu nangalo naliphi na ixesha lemini. Le kuphela kuthenga kufuneka ukuba unayo ngokwakho GPS-esasihamba, okanye isixhobo exhasa umsebenzi GPS. Enyanisweni, lo mgaqo usebenza esasihamba isekelwe phezu scheme elula yokukhangela elide-isetyenziswe: ukuba uyazi ncam indawo apho injongosenzi isiphawuli oko ifanelekileyo ukuze indima njengesikhokelo, yaye umgama kulo kuwe, bazobe isangqa apho uphawu kwindawo ingongoma yakho. Ukuba radius wesangqa mkhulu, ngoko endaweni kulo umgca othe ngqo. Chitha embalwa bands ukusuka kwindawo kunokwenzeka amakishayo yakho ecaleni, indawo ekudibaneni kwe-imigca baya kumakisha indawo yakho emephini. I-Hewana ngasentla kulo mzekelo, ukudlala nje indima yezi zinto isiphawuli umgama ukusuka kwindawo yakho malunga ne-18 amawaka km. Nangona orbit kwabo ukuphendula ehamba ngesantya esikhulu, indawo kusoloko ubekwe iliso. browser ngasinye efakwe GPS-receiver, nto leyo icwangciselwe kwi kumaza afunekayo, yaye xa zidibene ngqo kunye satellite. uphawu radio nganye equlethe nesixa ulwazi encoded, equka iinkcazo malunga nemeko lobugcisa bala satellite, indawo yayo phezu orbit kunye nezowuni koMhlaba (ixesha langoku). Hi ndlela leyi, iinkcukacha malunga nexesha esiza kakhulu eziyimfuneko ukufumana iinkcukacha malunga zilungelelanise zakho kwenzeka ukubala ubude bexesha phakathi ifuthe kunye nangokwamkela uphawu umsakazo liphindaphindwe isantya amaza erediyo kwaye ngu-isigxina izibalo ukubala umgama phakathi kwefowuni yakho navigation kwaye ndiza orbit.
ubunzima ungqamaniso
Ngokusekelwe kulo mgaqo yeNavigeyishini, siya kuthathwa ngokuthi ukufumanisa ngokuchanileyo isikhundla sakho ukuze kufuneka Hewana nje ezimbini, ngokusekelwe imiyalezo kuya kuba lula ukufumana kwindawo yonqumlo, yaye ngenxa yoko - indawo apho ukhoyo. Kodwa ke, ngelishwa, ngezizathu zobugcisa ifuna ukusetyenziswa satellite ngaphezu kwesinye ukuba amakishe. Eyona ngxaki inkulu iwotshi GPS-ngumamkeli ukuba ayikuvumeli ungqamaniso eyaneleyo kunye Hewana. Isizathu soku kukuba ukubonisa umahluko ixesha (kwi kwibhrawuza yakho kwaye space). Satellites abakhoyo iiwotshi ezikumgangatho ophezulu zodidi qho atom, ebavumela ukuba ukubala ixesha ngobuciko obukhulu, ngoxa abanye balwamkele eqhelekileyo athom ezinjalo nje akunakwenzeka ukuba isicelo, njengoko ubukhulu, indleko, ukuntsokotha kwi msebenzi akazange avunyelwe ukuba sizisebenzise kuyo yonke indawo. Nokuba impazamo encinane seconds 0.001 ungase uququzelelo abangaphezu kwe-200 km ngendlela!
umaki wesithathu
Ngoko ke ababhekisi bagqiba ekubeni ushiye iteknoloji zwi aqhelekileyo GPS-esasihamba kunye uye enye indlela, ukuba ngqo ngakumbi - ukusebenzisa endaweni ulwalathiso satellite-mbini - amathathu, ngokulandelelana, inani elifanayo imigca kwibhulorho ezilandelayo. Isisombululo isekelwe ngomnyango emangalisayo ilula: ekudibaneni kwe imigca emithathu ephawulwe markers, nkqu kwimeko ezingachanekanga kunokwenzeka, ukudala indawo kwi imilo unxantathu, kunye iziko leyo ethatha phakathi kwayo - indawo yakho. Iveza umahluko kwi ngexesha receiver kunye bonke Hewana ezintathu (apho umahluko kuyafana), oko ikuvumela ukunyenyisa ekudibaneni kwe-imigca ngqo kwiziko, ukuba nje - sichaza GPS yakho indawo.
enye frequency
Kufuneka kuqatshelwe ukuba zonke Hewana ethunyelwa ngayo inkcazelo ifowuni yakho qho olunye, kwaye oku kakhulu ezingaqhelekanga. Ingaba GPS-esasihamba kunye nendlela ukutolika njani yonke ingcaciso ichanekile, ukuba zonke Hewana ngokuqhubekekayo yaye kwangaxeshanye ulithumele ulwazi? Zonke pretty elula. zidlulisele Satellite ukujonga uphawu radio ngokwayo othunyelwe kwenye, yaye iinkcukacha ezilubala, nto leyo khowudi khowudi. Uthi satellite features eliphezulu yaye igcinwe kwiziko ledatha kwisixhobo sakho, nto leyo ke yenza ukuba uqinisekise ukuba idatha base data satellite. Naxa kukho inani elikhulu-Hewana ziindidi ngokukhawuleza kakhulu kwaye kalula ukubona. Konke oku lula yonke le nkqubo, kwaye ikuvumela ukuba usebenzise GPS-esasihamba zibencinane kwaye buthathaka-eriyali reception, leyo kunciphisa iindleko lize linciphise uyilo kunye nemilinganiselo ifowuni.
GPS-iimephu
GPS mephu kwifowuni yakho ngokwahlukileyo, njengoko wenza ukuphembelela ukukhetha indawo ofuna ukuhambisa. Le nkqubo ubeka kuphela indawo yakho emhlabeni, kwaye ikhadi umsebenzi kudalwa ngokutsha kwi kwinguqulelo lomzobo yeskrini nekufakwe kuzo uququzelelo, evumela ukuba uzulazule elimi ngayo. GPS nje umsebenzi kule meko? Free, yaye uhlala kule iwonga, ikhadi kwezinye kwiivenkile intanethi (hayi kuphela) nangoku ihlawulwe. Amaxesha amaninzi, ezi zicelo ngamnye zenzelwa Isixhobo GPS-esasihamba ukusebenza kunye neemephu: bobabini ihlawulwe kunye simahla. ikhadi iintlobo izimanga ezimnandi kwaye ikuvumela ukuba uqwalasele indlela ukusuka kwindawo A ukuya kwindawo B njengoko ulwazi kangangoko kunokwenzeka kwaye yonke aluncedo eniya ezinika ziya kudlula, le ndlela imfutshane ukuya khona, umncedisi ilizwi, ezibonisa indlela kunye nezinye.
Ezongezelelweyo GPS-izixhobo
inkqubo GPS lisetyenziswa kuphela ukubonisa indlela yakho oyithandayo. Ivumela elibukhali le into, leyo isenokuba CTLI ekuthiwa-okanye GPS-tracker. Luquka kwisamkeli uphawu kunye samaza ngokusekelwe GSM, 3gp okanye ezinye iprotocol zonxibelelwano ukuze udlulise ulwazi malunga indawo into kumaziko enkonzo, ukubonisa ulawulo. Bona zisetyenziswa mveliso ezininzi: ukhuseleko, unyango, i-inshorensi, uthutho kunye nabanye abaninzi. aba bazingeli imoto khona, abaqhagamshelwe kuphela imoto.
Ukuhamba ngaphandle naziphi na iingxaki
Yonke imihla ikhadi ixabiso kunye ikhampasi esisigxina singene nzulu kwixesha elidlulileyo. ubugcisa bale mihla ukuvumela umntu ukuhlahlela indlela uhambo lwakhe kunye nokulahlekelwa amancinane ixesha, amandla kunye nemali, ngaxeshanye ukuze abone iindawo ezininzi umdla umdla. Yintoni kwakuhle malunga kwinkulungwane edluleyo ngoku ngokwenene, kwaye ungasebenzisa phantse zonke emkhosini, oomatiloshe nabaqhubi-moya wabakhenkethi zeposi. Ngoku ukuzuza ukwandisa kuthandwa kunye nokusetyenziswa kwezi neenkqubo, ukuzonwabisa kunye izibhengezo mveliso zorhwebo, apho yonke umrhwebi zinokubonisa ngokwalo kwimephu ehlabathini lonke ihlabathi, yaye oko kuya kuba kakhulu lula ukufumana. Siyathemba ukuba eli nqaku iye yanceda ukuba wonke umntu onomdla, GPS - isebenza njani, yintoni isiseko, isigqibo of zilungelelanise, yintoni amandla kunye nobuthathaka yayo.
