GPS iyo A-GPS si wadajir ah u wada shaqeeyaan si deg deg ah iyo macluumaad sax ah
GPS-ka caawiyay, oo sidoo kale loo yaqaano "A-GPS" ama "AGPS", ayaa sare u qaadaya waxqabadka GPS-ga casriga ah iyo aalado kale oo mobile oo ku xiran shabakada gacanta. GPS-ga caawiyay waxay hagaajineysaa waxqabadka goobta laba siyaabood:
- A-GPS wuxuu ka caawiyaa telefoonka in uu si dhakhso ah " Time to First Fix ", (TTFF), taas oo si weyn u hagaajineysa waxqabadka bilawga ah. Gacan-ku-caawinta GPS wuxuu soo gadanayaa oo ku kaydiyaa macluumaadka ku saabsan goobta uumiyeyaasha iyadoo la isticmaalayo shabakada gacanta si aysan macluumaadka u baahneyn in lagu soo dejiyo satellite-ka.
- Gacmushtarka GPS taageeray telefoonka ama qalabka mobile marka signallada GPS yihiin daciif ah ama aan la heli karin. Calaamadaha dayax-gacmeedka GPS-ga ayaa laga yaabaa in laga hor istaago dhismayaasha dhaadheer, oo aysan ku dhex gelin dhismaha dhismaha si fiican. GPS-ka caawiyay wuxuu isticmaalaa meel u dhow munaaradaha gacanta si loo xisaabiyo jagada marka signallada GPS aan la heli karin.
Sidee GPS-ga iyo Gargaarka Gacmeedku u wada shaqeeyaan
Nidaamka GPS wuxuu u baahan yahay inuu samaysto isku-xirnaanta satellite-ka iyo inuu helo xogta orbada iyo saacadaha ka hor inta uusan ogaanin goobta. Tani waa waqtiga ugu horreysa ee lagu saxo. Nidaamku wuxuu qaadan karaa 30 ilbiriqsi ilaa dhowr daqiiqo ka hor inta qalabku uu ku heli karo calaamad - goorba inta uu ku xiran yahay hareeraha iyo xaddiga faragelinta. Goobaha furan ayaa si sahlan u helaya calaamad muujinaysa in ka badan magaalo dhisme dheer ah.
Marka qalabku isticmaalo GPS-ga caawiya, waqtiga si aad uhesho iibsiga waa mid deg deg ah. Taleefankaaga wuxuu ka jiidanayaa macluumaadka ku saabsan meesha laga soo galo maktabadda laga bilaabo munaarada gacanta ee ugu dhow, kaas oo badbaadinaya waqtiga. Natiijo ahaan, waxaad:
- Hel raadsasho degdeg ah
- Keydso nolosha batteriga
- Hel warsiinta goobta xitaa marka GPS ma heli karto signalka
Nidaam ahaan, GPS-ka gargaarku maaha meel u dhow gawaarida sida GPS-ga, laakiin wadajir u shaqeeya, labaduba waxay daboolaan dhamaan saldhigyada. Dhammaan telefoonada casriga ah waxay leeyihiin boorarka A-GPS ee iyaga, laakiin dhammaan telefoonada ma isticmaalaan. Markaad raadineyso casriga cusub, weydii haddii ay leedahay gabi ahaanba caawimaad madax-banaan oo GPS ah oo ah user user accessible. Tani waa qaabka ugu wanaagsan ee loogu talagalay dadka isticmaala, inkasta oo telefoonada qaarkood ay taageeraan. Telefoonada qaar ayaa laga yaabaa inay bixiyaan keliya A-GPS-ga ama GPS-ga caawiya ee aan la heli karin dadka isticmaala.
