About the GPS Module Operating Modes
The integrated GPS module has three operating modes:
• Standalone
• MS Assisted (Mobile Station Assisted)
• gpsOneXTRA™ (UMTS computers only)
In Standalone mode, the GPS module relies solely on GPS satellites to determine
position.
Note:
The CN75 and CN75e models with phone capability (WWAN radio) also support
GLONASS.
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.
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. To use this option, you must have a valid and
activated WWAN data connection.
Note:
Internet connection fees may apply.
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
Flexible Network Radio has a maximum interval of 4.
