Working with GPS

Overview

The Dolphin 60s terminal contains an integrated GPS module that allows location tracking of workers
and vehicles, providing better utilization of field assets. Optional mapping and navigation software
provides turn-by-turn driving directions and location information.

Assisted GPS Support

Assisted GPS (A-GPS) is turned on by default. The Dolphin 60s utilizes gpsOneXTRA Assistance™
Technology to improve time-to-first-fix (TTFF) positioning by using network resources for quicker satellite
identification. The carrier agnostic feature downloads a file (approximately 40KB) containing emphersis
data from a Qualcomm® server approximately every 7 days.
Note: A data connection is required and data transfer charges may apply depending on your carrier.
A-GPS can be turned off with the following registry key:
[HKEY_LOCAL_MACHINE\Software\Sierra Wireless Inc\swigobi\GPSSettings]
"GpsXtra"=dword:00000001
1 = enabled, 0 = disabled"

Powering the GPS Module

The GPS module powers on automatically when accessed by a software application and powers off
automatically when that software application closes. You cannot manually power on and off the GPS
module.

Communication Port

There are two ways to access the GPS module: through the actual COM port (COM7) or the GPS Inter-
mediate Driver. The method you use depends on the software application you are using. If the software
application requires the actual COM Port, set the operating system to use COM7. If the software appli-
cation requires the GPS Intermediate Driver, set the operating system to use the GPS Intermediate
Driver.

COM7

COM Port 7 can be set to the following baud rates:
• 4800
• 9600 (Default baud rate. Recommended for optimal performance.)
• 19200
• 38400
Other baud rates are not possible. The baud rate selected on COM7 is the actual baud rate with which
the GPS communicates.
