GPS Diagnostic<br />

Chapter 9 — Examining the <strong>Data</strong><br />

GPS Diagnostic by CommLinx Solutions is another great tool that enables you to work at a<br />

low level with the GPS data and NMEA. GPS Diagnostics is available as a free download<br />

from www.laipac.com/gps_gpsdiag_eng.htm.<br />

As you can see from Figure 9-4, what is different about GPS Diagnostics is that it displays<br />

interpreted data in the top half of the screen and the raw data in the bottom half.<br />

This excellent utility offers you a great deal in the way of customizations. You can choose to<br />

ignore certain NMEA sentences and select which timestamp to use (see Figure 9-5).<br />

The software also enables you to choose customized data fields to display (see Figure 9-6).<br />

Finally, GPS Diagnostics enables you to replay data that you’ve collected, and even choose the<br />

replay rate (see Figure 9-7).<br />
