Improving GPS Performance on the Computer
Use the iGPS application to improve the performance of the GPS on
your computer. The integrated GPS module has three operating
modes.
Integrated GPS Operating Modes
Another option you can configure with iGPS is the fix interval. The fix
interval defines how often the GPS should provide new information.
Larger intervals use less power, but many applications require small
intervals to work correctly. The default for fix interval is 4.
To improve GPS performance using iGPS:
1 Go to Start > Settings > System > iGPS .
2 In the Fix Interval field, enter a value for the fix interval. The
default setting is 4 and should be optimized for most applications.
Operating Mode Description
Standalone In Standalone mode, the GPS module relies solely on GPS
satellites to determine position.
MS Assisted In MS Assisted mode, the computer can determine
position without receiving GPS signals directly from
satellites; instead, the computer receives GPS signals and
information provided by the cellular network. Even when
the computer can receive a satellite signal, MS Assisted
can improve position accuracy and reduce the time to
determine initial position (Time-To-First-Fix). Check
with your cell phone carrier for availability and pricing for
MS Assisted service.
gpsOneXTRA™ Qualcomm’s gpsOneXTRA Assistance technology
provides enhanced operation for Standalone GPS. This
option enables the UMTS-enabled computer to
automatically download a small assistance data file from
the XTRA servers through a brief internet access session.
Note: Anytime you change the GPS settings, the phone module
automatically resets. This reset does not affect the functionality of the
computer.
