Location Discovery; Launch Gps & Agps - CipherLab CP50 Manual Manual

5.6. LOCATION DISCOVERY

Adorned with a GPS module, the mobile computer is capable of finding your location on
earth. GPS relies on the satellites covering the sky around the world to pinpoint your
whereabouts. With mobile data (HSPA+ (3.8G); available on CP50 G), the mobile computer
even delivers A-GPS, which accelerates location discovery by combining GPS and
cell-tower-distance triangulation. With HSPA+ (3.8G) data, the mobile computer is also
E911-compatible to get help for endangered 911 callers.
A location-aware application is necessary. CipherLab's
mobile computer for NMEA-based location discovery. There are other applications
downloadable from Internet. Download the ".cab"-suffixed programs that confirm the
compatibility with Windows Embedded Handheld 6.5. Note always download programs from
trusted sources.
As GPS is a big power consumer, close GPS application when you are not using it.
5.6.1. LAUNCH GPS & AGPS
The O.S. doesn't feature any facility to turn on/off GPS module but a GPS intermediate
driver (hereinafter "GPSID"), a software layer between GPS hardware and GPS software to
stream GPS data from hardware to software without parsing NMEA syntax and in the
meanwhile enable multiple applications to simultaneously access GPS data.
Hence the approach to turn on GPS module is to launch a GPS software or a location-aware
application on the mobile computer because the software COM port for GPS is turned on
then. In case of any difficulty launching GPS, open Start screen | Settings | System |
External GPS | Access tabbed page to check if Manage GPS automatically is selected.
