Ukutyhila umahluko phakathi kwe-GPS kunye ne-GNS

I-GPS, emela inkqubo yokubeka i-Global, yinkqubo yokutyala ekwakheni yeSathellite eyaphuhliswa kwaye iqhutywa ngurhulumente we-United States. Inomnatha wenethiwekhi ezingama-24 ijikeleza umhlaba, ukuhambisa ixesha elifanelekileyo kunye nendawo yendawo kubamkeli beGPS. Aba bamkeleyo basebenzise olu lwazi ukubala indawo yabucala yomsebenzisi, ukuvalwa, kunye nexesha. I-GPS ibe sisixhobo esibalulekileyo kuluhlu olubanzi lwezicelo, kubandakanya umkhosi, inqwelo moya, elwandle, kunye noluntu.

Kwelinye icala,GnsLigama eliqhelekileyo elibandakanya kungekuphela kwenkqubo ye-GPS kodwa nezinye iinkqubo ezifanayo eziphuhliswe ngamanye amazwe. Eyona nto ixabisekileyo yezi yinkqubo ye-glossass yaseRussia, inkqubo ye-European yeGalileo, kunye neNkqubo yaseTshayina yeBeidou. Ezi nkqubo zisebenza kwimigaqo efanayo yesiseko njenge-GPS, esebenzisa inethiwekhi yesatellites ukuba ibonelele ngendawo kunye nexesha lokufumana ixesha kubasebenzisi kwihlabathi liphela.

Owona mahluko ophambili phakathi kwe-GPS kwayeGnslinani lesathelayithi kwiqela elichaphazelekayo. Ekuqaleni i-GPS iquka iisatellite ezingama-24, kodwa eli nani lelonyuke laya ngaphezulu kwama-30, elinikezela ukugubungela okukhulu kunye nokuchaneka. I-GNS, kwelinye icala, idibanisa iisatellite kwiinkqubo ezininzi, ezikhokelela kwikhonkco elikhulu kakhulu kwaye linokugubungela ngakumbi, ingakumbi kwiindawo ezinomngeni okanye amahlathi amnyama.

Olunye umahluko obalulekileyo yinqanaba lokuchaneka kunye nokuchaneka kwe-GPS kunye ne-GNS. Ngelixa zombini iinkqubo ziyakwazi ukubonelela ngolwazi oluchanekileyo lokuhlala, ii-GNSs zinokubakho ukubonelela ngokuchaneka okukhulu ngenxa yenani leesatellite kunye nokukwazi ukufikelela kwiinkwenkwezi ezininzi ngaxeshanye. Oku kunokuba luncedo ngokukhethekileyo kwizicelo ezifuna amanqanaba aphezulu okuchaneka, njengokuphononongwa, kwezolimo ezichanekileyo, kunye nendawo ye-geodetic.

Ngokwamalunga nokufumaneka, i-GPs yembali ibiyeyona nto isetyenziswa kakhulu kwaye ifikeleleke kakhulu yesatellite. Nangona kunjalo, ngokuphuhliswa kweenkqubo ezongeziweyo ze-GNS ezifana neGalileo naseGeidou, abasebenzisi ngoku banokufikelela kuluhlu oluqhelekileyo lwesatellite, enokukhokelela ekuphuculeni umsebenzi ophuculweyo, ngakumbi kwimimandla ye-GPS anokuthi athintele okanye ayonakalisiweyo.

Ngapha koko, ii-GNSs zibonelela ngenzuzo yokungafuneki kunye nokomelela. Ngokusebenzisa uninzi lwesatellite, abasebenzisi be-Gnss banokuxhamla kwi-ortism eyandayo kunye nokuthembeka. Kwimeko yokuphazamiseka kwesatellite okanye ukuphazamiseka kwesibonakaliso, abamkeli be-Gnss banokuthi batshintshele kwenye indawo yokusebenzisana, ukuqinisekisa ukusebenza okuqhubekayo kunye nokunciphisa umngcipheko wokuphazamiseka kwenkonzo.

Ukusuka kwimbono yetekhnoloji, i-GNSs ikwanakho ukuxhasa uluhlu olubanzi lweempawu kunye neenkonzo xa kuthelekiswa ne-GPS yedwa. Umzekelo, inkqubo yeGalileo ibandakanya amanqaku anjengenkonzo evulekileyo, enika ukufikelela simahla ukubeka kunye nexesha lokujonga ixesha, kunye nenkonzo elawulwa ngurhulumente, ebonelela ngorhulumente okhuselekileyo noorhulumente abagunyazisiweyo. Ezi zixhobo ezongeziweyo zikhuthaza ukusetyenziswa kunye nokungaguquguquki kwee-GNSs zeZicelo ezahlukeneyo kunye namaqela abasebenzisi.

Ukuqukumbela, ngelixa i-GPS kunye nee-GNS zabelana ngeenjongo ezifanayo zokubonelela ukubekwa kwehlabathi kunye nezahlulo ezihlukileyo, kukho umahluko ohlukileyo phakathi kweenkqubo ezimbini ngokweenkqubo zokwenza indawo ngokwezixhobo ze-connelting, ukulungisa, ukomelela kwezobuchwephesha. Njengoko intsimi yendawo yokuhamba ngeSatellite iyaqhubeka ivela, ukudityaniswa kweengqungquthela ezininzi ze-Gnss kunika amandla okusebenza okuphuculweyo kunye nokuthembeka, ukusebenzisa abasebenzisi bokuxhamla, abasebenzisi abaninzi kuluhlu olubanzi lwamashishini kunye nemisebenzi. Ukuqonda umahluko phakathi kwe-GPS kunye nee-GNS kubalulekile ukuba bafumane amandla apheleleyo etekhnoloji yokuhamba ngeSatellite kunye nokuqinisekisa ukuba abasebenzisi behlabathi.
