The integrated Global Positioning System (GPS) receiver in your CN4
delivers standards-based National Marine Electronics Association
(NMEA) data strings to GPS applications. However, 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.
Using the GPSID allows Intermec support for 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.
