Kuyini GPS: isimiso ukusebenza, isicelo ukukhubazeka

Namuhla, iziphuphutheki yokufakelwa ngenkuthalo lisetshenziswe sphere eziningi zokuphila kwethu. Kuye saphela eseyintsha TV satellite Inthanethi. Kungokufanayo iba komkhuba kanye satellite navigation system GPS. Hlobo luni system, futhi yini izinkinga okuyixazululayo?

Umgomo we operation

Ukuze uqale, ake ukubhekana neqiniso lokuthi GPS enjalo. Lokhu isifinyezo livela amazwi English of Global ukuma System - Global Positioning System. Ngakho sikubiza uhlelo satellites, yona eyaqala ukwenza i ukuthuthukisa emuva 1970 i-United States. In the 80s ke wayevunyelwe ukusebenzisa abavamile. Uhlelo GPS kusiza ukuhlonza indawo ngqo bese uhlela into yokuhamba. Satellites umsebenzi ayitsintseki izimo zezulu, ukuze isistimu usebenza ubusuku nemini.

Inzuzo main kwalesi simiso - mahhala. Ukuze ufunde futhi sithola ukuthi i-GPS, udinga kuphela ukuthenga umamukeli akhethekile isofthiwe. Lesi sakamuva kuyinto ibalazwe electronic esifundeni lapho ukhona, futhi uhlelo A-GPS, okuyinto esetshenziswa sezulu esinamafu. It uxhuma iseva ekhethekile, equkethe ulwazi mayelana izixhumanisi kumasathalayithi eliseduze. Namuhla uhlelo kuzo zonke Itilosi imoto.

Kanjani navigation GPS? Ukuhambisa omise isiyingi we satellite 24, ngalinye elikwazi wenza 2 linemibhikisho ngelanga futhi adlulisele amasignali. Ukuthatha kubo, GPS-umamukeli sinquma isikhundla salo. Okokuqala, umehluko phakathi isignali isikhathi ibalwa kokunikeza nokwamukela isikhathi. ibalwa Ngakho Ibanga satellite. Uma labo owamukelayo indawo endaweni, kunezindlela okungenani ezimbili, kungaba ukucacisa nobude, esemgwaqweni bese umaka ngokwakho emamebheni electronic. Uma ushutha iziphuphutheki ezine noma ngaphezulu isofthiwe umamukeli sinquma hhayi kuphela nobude, kodwa futhi ijubane into, futhi ibanga esele uhambo, isikhathi ukuphuma nokushona kwelanga , kanye naletinye tindlela tekuphila eziningi. Positioning ukunemba GPS-abamukelayo namuhla kusuka 5 kuya ku-20 m (ukuphakama - 10 m).

sphere kwesicelo

Ngakho-ke yini i-GPS, siye safunda le. Kukuziphi izici ingasisebenzisa kanjani lesi simiso? Cishe kuzo zonke.

Siqala umsebenzisi ezivamile futhi aziwayo ububanzi. Lokhu amatilosi imoto. Eqinisweni, kungcono amakhompyutha, okuyiwona bethole indlela ekhethekile yokusebenza esetshenziswa. Sebevele efakwe isofthiwe navigation ukuthi ukushintsha awunakuba khona ngaphandle kokuthethelela yokwephula ilayisensi. Ngaphezu ukuma esikhaleni ezisemadolobheni, Amatilosi ukunikeza a lot of izici ezengeziwe - angasetshenziswa ukubuka izithombe, ukudlala umculo, amavidiyo, ukuxhuma kwi-Inthanethi.

Car Navigator ngenkuthalo isetshenziswe kuphela abashayeli abavamile, kodwa futhi ukuthutha izinkampani. Phela, uhlelo GPS ikuvumela ukuba ulandele umzila nge wezimpahla izimoto ezilandelwa futhi lisabela ngokushesha ukubambezeleka kungenzeka. Uma kukhona inzwa usebenzisa lesi simiso singasetshenziswa elibukhali ukusetshenziswa kukawoyela.

Esinye isici esibangela isicelo - navigation abahamba ngezinyawo. Kukhona Itilosi compact ukuthi ingasetshenziswa ukukhempa uhambo futhi izintaba. Ziyakwazi okunye okuhle kumephu evamile futhi ikhampasi. Amatilosi singasebenza bafakwe kumadivayisi eselula - Smartphones. Ukunemba izixhumanisi kuleli cala ephansi kakhulu kunaleyo abamukelayo ezivamile, kodwa abakhiqizi ngenkuthalo ukusebenza ekuthuthukisweni software navigation.

Ngaphandle kweqiniso lokuthi GPS enjalo, awukwazi bayakhohlwa amaphutha zalesi simiso. izinga Reception kuthinte ukuminyana ezisemadolobheni, khona izihlahla uhlaza obukhulu, imithombo ezweni-based amasignali omsakazo nezinye izinto bagxambukele ezindabeni zethu. Kodwa inkinga eyinhloko - kuyinto ukwencika umsebenzi iziphuphutheki entandweni amasosha aseMelika. Asikho isiqinisekiso sokuthi ngesikhathi esisodwa ngeke kudingeke isiphazamiso noma umane ukuvimbela wemboni yombango yisiphi isifunda. Ngenhlanhla, manje kukhona kakade okunye navigation systems, okuvumela hhayi "ulahleke" kuleli cala. Lona GLONASS Russian kanye uGalileo European. Abakhiqizi amatilosi futhi ulungiselela zimo futhi njengoba ezizimele ekuthuthukiseni chips ezingaba asekele zonke uhlelo ezintathu navigation.
