Working with GPS

Overview

The Dolphin 9900 terminal contains an integrated GPS module which 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, allowing workers to arrive on time.

Assisted GPS Support

The operating system software does not inhibit nor explicitly support assisted GPS modes, which usually
requires installing a vendor-specific client on the 9900 that communicates with the GPS module. This
client would then provide the almanac and/or ephemeris data for warm or hot start modes of operation,
allowing a lower time to first fix (TTFS). The Client must be configured on the 9900, active, and provide
the data to the GPS module through the standard COM port.

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 Ports

There are two ways to access the GPS module: through the actual COM port, which is COM7 or the GPS
Intermediate Driver. Which 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
application requires the GPS Intermediate Driver, set the operating system to use the GPS Intermediate
Driver.

Selecting the Port

1. Tap Start > Settings > System tab > External GPS.
2. In the GPS program port: drop-down list, select COM7 or GPD1 (the GPS Intermediate Driver) as
required by the application.
3. Tap OK to save.
