About the Integrated GPS on Your Computer
Intermec recommends that you use the GPS Intermediate Driver
(GPSID) instead of directly accessing the GPS hardware. The GPSID is
a Microsoft software component that interacts between applications
and the GPS hardware. The GPSID supports Extended Ephemeris,
which enhances GPS performance by:
• reducing the amount of time it takes your GPS receiver to acquire
a fix.
• eliminating the need to obtain precise satellite data information
from the GPS satellites.
As a Microsoft software component, the GPSID also:
• allows multiple applications to simultaneously access the GPS data
stream.
• provides access to GPS data without requiring applications to
recognize and parse NMEA syntax.
Using the GPSID Installed on the Computer
To use the GPSID installed on your mobile computer, you need to
configure the GPSID settings.
To configure your GPSID settings:
1 Tap Start > Settings > System > External GPS. The GPS Settings
screen appears with Programs selected.
