- bayindirh 8y agoAssisted GPS talks with the towers around, pings them for distance and gets their coordinates. It's happening on the GSM layer. It's also a no-data exchange IIRC.
- gsich 8y agoNo, I think it's only downloading almanach data for faster GPS.
- bayindirh 8y agoIt's one of the operational modes. On the other mode it calculates the location on behalf of the user and responds back with it [0]. In both modes data connection is required, so I'm mistaken. [0]: https://en.wikipedia.org/wiki/Assisted_GPS https://en.wikipedia.org/wiki/Assisted_GPS
