6. Getting Started
There are only few simple steps that you need to follow before using your UD-731N:
Install the USB driver onto your laptop using the included CD-ROM .
Plug the GPS receiver into your laptop’s USB port and assign the COM port. From
within your mapping or navigation software (including the supplied GPS
Application utility), you will need to manually configure the COM port that was
assigned to the UD-731N GPS receiver by operation system so that proper
communication between the GPS receiver and a mapping program can occur.
Most software requires that you manually configure the COM port setting for any
GPS device being used.

8. Application Software Introduction
8.1 u-Center
The u-Center application software is provides by u-blox to support the devices with their
GPS chipset built-in. This section describes the simple and quick user guides to this useful
program. Please refer to the user manual of this software for more details.
8.1.1 Features
u-center evaluation software provides system integrators and end users with a quick and
simple way to interface with u-blox GPS chipsets, modules and boards. It enables easy
evaluation, performance testing, development and debugging of GPS receivers. u-center
allows easy connection to u-blox products and provides a suite of features to view, log, and
analyze performance. The features include:
Support for u-blox’ latest receivers using u-blox 5 positioning technology. u-center can
communicate with these receivers using either the UBX protocol, or the NMEA-0183
standard protocol.
Support for receivers that utilize standard NMEA strings.
u-center presents all the information collected during the operation of the GPS receiver.
All aspects of GPS data (position, velocity, time, satellite tracking, etc.) can be monitored
and logged under various test scenarios for the evaluation of a receiver. u-center
software allows analysis of the collected data in order to investigate performance issues
such as accuracy, road test position and trajectory, satellite tracking, time to first fix, etc.
All processed data can be captured in ASCII format and ported into popular
spreadsheets for creating additional plots and statistics.
Camera View: photographic data can be stored in the log file together with the navigation
data and later be replayed in the application.
Export data files to Google Earth and Google Maps.
Supports AssistNow Online and AssistNow Offline.
Data recording and playback function.
Structural and graphical data visualization in realtime.
Cut and paste export to standard PC application software.
Docking views (real-time cockpit instruments): Satellite constellation, compass, clock,
altimeter, speedometer, GPS and satellite information views.
