It has gpsOne, designed to meet the
FCC requirement to be able to locate
cellular 911 callers. It can operate in one of three modes:
1) The network provides information about the GPS satellites and nearby
cell sites to the phone, the phone measures the signals from the
satellites, as well as gathers info about the distance from nearby cell
sites, and reports the info back to the cell site, which computes the
location of the phone (combining both the GPS info and triangulation
info) and forwards it to the the E911 center or back to an application
on the phone.
2) Like (1), except that the phone itself does the computation of the
phone's location for the benefit of an application running on the phone.
I believe that this is the mode the V325 uses. Once the phone gets the
required info from the network, it can make multiple location fixes on
its own.
3) Full GPS.
(1) and (2) allow the location fix to happen where a standalone GPS
receiver won't work, like indoors or between tall buildings, but require
communication with at least one cell site. (1) and (2) also get a fix
much faster than a cold-started standalone GPS unit (important for 911 use).
It would be up to the applications running on the phone to provide NMEA
data. Haven't heard anything about that.
