Improve GPS Performance on the Computer
Use the iGPS application to improve the performance of the GPS on your i.roc® Ci70 -Ex com-
puter. The integrated GPS module has three operating modes:
• Standalone
• MS Assisted (Mobile Station Assisted)
• gpsOneXTRA™ (WWAN computers only)
In Standalone mode, the GPS module relies solely on GPS satellites to determine position.
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 assis-
tance data le from the XTRA servers through a brief internet access session. To use this option,
you must have a valid and activated WAN data connection.
Note: Internet connection fees may apply�
Another option you can congure with iGPS is the x interval. The x interval denes 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 x interval, in seconds, is 4. The Flexible
Network Radio has a maximum interval of 4.
Note: Anytime you change the GPS settings, the phone module automatically resets�
It will not affect the functionality of the computer�
To improve GPS performance:
1 Go to Start > Settings > System > iGPS.
2 In the Fix Interval tab, enter a value for the x interval. The default setting is 4 and should
be optimized for most applications.
3 Tap the Fix Type tab and select one of these options: Standalone (1), MS assisted (2), or
Enable gpsOneXTRA (check box).
4 Tap OK.
