We've been through several versions now, so things are pretty stable. I'm just making minor feature enhancements from time to time now as I hear from users.
The last round of changes was to fix some problems with numeric formats which use "1,00" as a floating point number format instead of my native "1.00" usage.
I purchased Microsoft's Streets & Trips mapping software because I thought it might come in handy for some planned travelling. It included a USB GPS that the software used to show real-time location updates. That was really cool and helped me on trips when I had the laptop running in front of my car's co-pilot, but I had no idea what the GPS was telling my PC across that USB cable.
After a few web searches, I found out a lot of cool information that comes out of a GPS, but Streets & Trips didn't show any of it. I decided it was time for a little coding to satisfy my curiosity.
Here's the raw NMEA data display. It's not terribly readable compared to the graphs and maps.
One thing led to another, and before I knew it, I had created GPSMonitor. It has azimuth and elevation graphs of active satellites, a Google map, and data logging. It wasn't quite the little project I'd started.
I currently display GPS data for GSV, RMC, GGA, GGL, and GSA tags, each on its own tab in the main window.
My hope is that I will have saved you, a fellow GPS owner, a bit of time in satisfying your own curiosity.
There's a built-in web page that shows a map of your location based on your GPS readings. Clicking on the mini-screenshot will take you to the actual map page. Of course this feature only works if you're hooked to the Web while you're playing with your GPS.
GPSMonitor requires .NET 4.0 to be installed, which may be downloaded from Microsoft Corporation here. It is large, so you may want to plan for a time when you can let the download run for a while. Low-speed modem users can order the update on CD from Microsoft.
Vista and Windows 7 come with the .NET runtime already installed to at least version 3.something, so you should be good to go if you just update to 4.0 through the regular Windows Updates.
Let me know if you have any ideas for me on what to add in.
