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.
