GPS NMEA LOG
Chapter 9 — Examining the Data
GPS NMEA LOG might be an unimaginative title, but the software does exactly what is says
it will — enable you to see and log NMEA data from your GPS (see Figure 9-1).

This application can be downloaded from http://frankl.comdesign.at/Geo/
GPSNMEA.html.
To run this application, you might need to download the Visual Basic runtime file VBRUN300.DLL.
This can be found on many sites on the Internet. Copy this file into the system32 subfolder
where your Windows operating system is installed.
This is a simple but effective application that requires only a small amount of hard drive space
and RAM, making it ideal for older systems and laptops.
GPS NMEA LOG can also display real-time information decoded from the NMEA sentences
for times when you don’t feel like decoding NMEA (see Figure 9-2).

On this site you will also find another useful application — GPS data logging software. This
enables you to hook your GPS to a computer and have it log data. The software comes in both
Windows (WINNGPS) and DOS (NGPS) formats and can run on a variety of systems,
including old, run-down PCs for which you might not have much use.
