3G 版先有

sohoriho

3G版有GPS+AGPS,可以定位及使用導航功能（需apps配合）

Wifi版有AGPS,只能定位（大約位置）,沒有導航功能

IPAD WIFI只有樓上講既假LOCATION SERVICE, 以前有POST分別講過, 而呢個SERVICE, 絕對唔係叫AGPS

Mr123

上次 patwong1998 兄post 過:

GPS=傳統GPS定位
AGPS=ASSISTED GPS=基站定位+傳統GPS定位

IPAD WIFI係冇GPS, 佢定到位係因為可以用WIFI既基站定位
IPAD 3G有AGPS, 即係基站定位又得, 傳統又得

Hybrid positioning systems use a combination of network-based and handset-based technologies for location determination. One example would be some modes of Assisted GPS, which can both GPS and network information to compute the location (although in most A-GPS systems all computations are done by the handset, and the network is only used to initially acquire and use the GPS satellites).
