Ukuncedisa i-GPS, i-A-GPS, i-AGPS

I-GPS kunye ne-A-GPS basebenzisene kunye nokuThengisa ngokukhawuleza kunye nokuchanekileyo indawo yengcaciso

Incediso yeGPS, eyaziwa ngokuba yi-A-GPS okanye i-AGPS, inyusela ukusebenza kweGPS ephezulu kuma-smartphones nakwamanye amadivaysi eselula axhunyiwe kwinethiwekhi yeselula. Ukuncediswa kweGPS kuphucula ukusebenza kwendawo ngeendlela ezimbini:

• I-A-GPS inceda ifowuni ifikelele ngokukhawuleza " Isikhathi sokuQala ukuQala ," (iTTFF) esenza ngcono kakhulu ukusebenza kokuqalisa. I-Assisted GPS ithola kwaye igcine ulwazi ngolwazi lweendawo zeesatelliti usebenzisa inethiwekhi yeselula ukuze ulwazi aludingeki lilayishwe yi-satellite.
• Izibonelelo ze-GPS zixhaswe ifowuni okanye ifowuni yeselula xa iimpawu ze-GPS zibuthathaka okanye zingekho. Izibonakaliso ze-GPS zepetroli zingashukunyiswa zizakhiwo ezide, kwaye abazingenise ngaphakathi kwakhiwo ngaphakathi. Incediso yeGPS isebenzisa ukusondela kwiibhobho zamaselula ukubala indawo xa izibonakaliso ze-GPS zingekho.

I-GPS kunye neNcedisi ye-GPS isebenza njani kunye

Inkqubo ye- GPS idinga ukudibanisa i-satellite kunye nokufumana i-orbit kunye nedatha yewashi ngaphambi kokuba ikwazi indawo yayo. Eli lixesha lokuQala ukuQala. Inkqubo inokuthatha ukususela kumasekhondi angu-30 ukuya kwiminithi emininzi ngaphambi kokuba idivayisi yakho ikwazi ukufumana isigxina-ngokuqinisekileyo kuxhomekeke kwimizuzu engqongileyo kunye nemilinganiselo yokuphazamiseka. Iindawo ezivulelekileyo zilula ukufumana uphawu kunesixeko esinezakhiwo ezide.

Xa ifowuni isebenzisa i-GPS encedisiweyo, ixesha lokufumana uphawu lokufumana ngokukhawuleza. Ifowuni yakho idonsa ulwazi malunga nendawo yeesatelliti ukusuka kwinqaba yeselula esondeleyo, egcina ixesha. Ngenxa yoko, wena:

• Fumana ngokukhawuleza ukufumana isignali
• Londoloza ubomi bhetri
• Fumana ulwazi lwengingqi nangona i-GPS ingenakufumana uphawu

Ngokwalo, uncedisa i-GPS ayimiseli ifowuni yeselula ngokukhawuleza njengeGPS, kodwa esebenza kunye, ezi zimbini zihlanganisa zonke iziseko. Zonke iifowuni zanamhlanje zinesixhobo se-A-GPS kuzo, kodwa akuzona zonke iifowuni ezisetyenziswayo. Xa ukhangele i-smartphone entsha, buza ukuba izele, igxininisekile i-GPS enokufumaneka komsebenzisi. Olu luqwalaselo olungcono kubasebenzisi, nangona iifowuni kuphela zixhasa. Ezinye iifowuni zinikela kuphela i-A-GPS okanye incediswe i-GPS engenakufikeleleka kubasebenzisi nonke.
