I-Global Positioning System (i-GPS) yimbonakaliso yobugcisa eyenziwe yile iqela lama-satellites ekujikelezeni komhlaba okuhambisa izibonakaliso ezichanekileyo, ukuvumela abamukeli be-GPS ukuba babale kwaye babonise indawo echanekileyo yendawo, isantya kunye nexesha kumsebenzisi.
Ngokuthabatha iimpawu ezivela kwiisatelliti ezintathu okanye ngaphezulu (phakathi kweenkcukacha ze-satellites ezingama-31 ezikhoyo), abalamkeli be-GPS banako ukuhlaziya idatha kunye nokukhomba indawo yakho.
Ngokudibanisa kwamakhompyutha kunye nedatha egcinwe kwimemori efana nemephu yeendlela, amanqaku anomdla, ulwazi lwezobugcisa kunye nokunye okuninzi, abafumene i-GPS banako ukuguqula indawo, isivinini kunye nolwazi lwexesha zibe yindlela yokwenza ifayile efanelekileyo.
I-GPS yenziwe ngokusekwa yiSebe lase-United States loKhuselo (iDOD) njengesicelo somkhosi. Inkqubo iye ya sebenza ukususela ekuqaleni kwee-1980 kodwa yaqala ukuba luncedo kubantu abahlali ekupheleni kwee-1990. I-GPS yabathengi sele ibe yimboni yeebhiliyoni eziligidigidi kunye neentlobo ezininzi zeemveliso, iinkonzo, kunye neenkonzo ezisekelwe kwi-intanethi.
I-GPS isebenza ngokuchanekileyo kuzo zonke izimo zemozulu, imini okanye ubusuku, malunga newashi nakwihlabathi lonke. Akukho mrhumo wokubhaliselwa ukusetyenziswa kwezibonakaliso ze-GPS. Izibonakaliso ze-GPS zingavalwa ngehlathi elinamahlathi, izindonga ze-canyon, okanye izakhiwo zendawo, kwaye azingeneli kwiindawo zangaphakathi kakuhle, ngoko ezinye iindawo ezingavumelekanga ukuhamba kwe-GPS echanekileyo.
Abamkeli be-GPS ngokubanzi bachanekileyo ngaphakathi kweemitha ezili-15, kwaye imimodeli emitsha esisebenzisa iMpawu yokuNyuselwa kweNdawo yeNdawo yeeNdawo (WAAS) zichanekileyo zingakapheli ezintathu.
Nangona i-US kunye ne-GPS esebenzayo njengamanje yindlela esebenzayo kuphela, ezinye iinkqubo ezihlanu ze-navigation-based ezisisiseko se-satellite ziphuhliswa zizizwe ngezizwe kunye namaqela angamaqela amaninzi.
