Chapter 5 Using a GPS Navigation

Overview
NAUTIZ X3 adopted a GPS (Global Positioning System) technology using SiRF III chipset. GPS
technology is based on GPS satellites that transmit digital wireless signals constantly orbiting
the Earth. Those wireless signals contain precise time data, and this signal is used for identifying
the location of a user.
Warning!
The user is responsible for the safe use of SW30 in a car by correctly fixing it on a safe place
free from blocking vision or causing accidents, injuries, or damages. A driver must drive safely,
attending to all traffics, and take special care not to risk safe driving by using this device. To use
this device while driving is dangerous.
Installing a software
- A GPS navigation software released by a third party is necessary, and several evaluation copies
of such software are available from various manufacturers. For instance, to use VisualGPS, please
visit http://www.visualgps.net/VisualGPSce/
.
If you want to purchase a GPS navigation software, please ask the GPS manufacturer that the
software you are going to buy is compatible with NAUTIZ X3 before purchasing or downloading
or installation. For the installation and configuration of applications, please refer to the user's
manual for the relevant application.
Setting up GPS on NAUTIZ X3
- The basic features of NAUTIZ X3 are as follows:
1. Choose Start > Settings > System > External GPS.
2. Set GPS program port to COM4 from the program tab.
3. Set GPS program port to COM9 from the hardware tab.
4. Set baud rate to 9600 from the hardware tab.
Several programs can access GPS data simultaneously. Each program must access GPS data
using Microsoft GPS API or COM8.
Operation
- Though there is a default setting, it is subject to change.
- It may take from a few seconds to several minutes before receiving satellite signals. The
outdoor location where there are no obstacles blocking the sky is ideal. If such a location is not
available, it may take longer time to receive the signals or NAUTIZ X3 may be unable to
calculate the initial position quickly. In case of indoor use, the access to GPS signals may be
restricted or impossible.
