XT Series Device GPS Functionality
Janam XT Series devices provide integrated GPS functionality featuring u-blox 6 AMY-6M GPS receiver
technology, engineered to meet the needs of mobile handheld applications. Fast satellite acquisition and
excellent tracking performance combine to offer accurate navigation information.
In order to acquire the GPS data, third party navigation software is required. For Demo purposes, the
XT Series device has an application from u-blox installed in the Start Folder, called u-CenterMobile. For
additional information from u-blox visit http://www.u-blox.com
It may take a few minutes to acquire satellite signals and the best results will be obtained when the XT
Series device is positioned outside with a clear and unobstructed view of the sky. When indoors or without
a clear view of the sky, the acquisition time to get a fixed position will take much longer or the GPS signal
may be completely unavailable. GPS performance can also be negatively affected if your vehicle has
thermal glass windows, so position your XT85 where there is a clear view of the sky.
In addition, Janam’s XT Series supports Assisted GPS (A-GPS) modes, which significantly increases the
time to acquire a fixed position, also called Time To First Fix (TTFF). Visit http://www.u-blox.com for more
information.
Also the power to the GPS module will turn off when the XT Series device suspends, so after resuming
there could be a delay in receiving the GPS data depending on where the unit is located upon resuming.
To set up the GPS function:
The XT85 Operating System manages access to the GPS module and can allow multiple programs to
simultaneously access GPS data. The default settings are as described below:
1. From the Windows Mobile Start screen, tap the Settings (icon) > System
(folder) > External GPS (icon).
2. Under the Programs Tap, the GPS program port (or virtual port) will be set to
COM9
3. Under the Hardware Tab, the GPS hardware port will be set to COM7 and Baud
rate of 9600.
4. In order to have multiple programs access the GPS data simultaneously, then
each program should acquire the GPS data through the virtual port (COM9). If
one program uses COM7 to access the GPS data then that program will have
control over the GPS module and block other programs from acquiring data.
