"In fact, Qualcomm, who makes the most popular aGPS chips (called GPSOne) has four different possible configurations for aGPS. How aGPS is actually implemented on the device appears to be up to the device OEM/cellular carriers.
These four options are:
Standalone - Your handset has no connection to the network, and uses only the GPS satellite signals it can currently receive to try and establish a location. 
MS Based - Your handset is connected to the network, and uses the GPS signals + a location signal from the network. 
MS Assisted - Your handset is connected to the network, uses GPS signals + a location signal then relays its 'fix' to the server, which then uses the signal strength from your phone to the network towers to further plot your position. You can still maintain voice communication in this scenario, but not 'Internet/Network service' ie Web Browser, IM, streaming TV etc.. 
MS Assisted/Hybrid - Same as above, but network functionality remains. Normally only in areas with exceptional coverage. "

kokiu lygiu bus naudojamas, priklauso nuo aparato gamintojo. sakykim tavo pda, kaip htc aparatai, ima duomenu faila is serverio kiekviena kart, kai tu ji jungi prie kompo, tu gali ir nepastebeti, kad rysys naudojamas, nors ir ne omnitelio. o bet taciau, kalbant apie pilnaverti agps, tai rysys reikalingas nuolat.

atkreipk demesi, as niekur neskiau, kad koordinates bus gaunamos internetu. betkokiu atveju, yra gps imtuvas gaudyti satelitu signalams.

kitavertus, kazkodel esi isitikines, kad tavo aparatas su agps yra pats agps`iskiausias pasaulyje. nors gal jis stovi pirmame laiptelyje, ir agps ten tik uzrasas.

taigi, koks tavo aparatas, ir kokias agps funkcijas jis atlieka?
