NMEA Sentences Checksum Calculator

NMEA Sentences Checksum Calculator is a handy Java-based software tool that helps you calculate and verify the NMEA sentence checksum used with GPS devices. If you're working with GPS tech, this tool can be a real lifesaver!

Understanding NMEA Messages

Every NMEA message kicks off with a dollar sign and wraps up with an asterisk followed by a two-digit hexadecimal checksum. The main job of this utility is to help you find those two digits at the end of the NMEA string.

Portable and Easy to Use

This program comes in a portable package, meaning you can skip the whole installation hassle. Just run the EXE file to access the app’s user-friendly interface! Plus, when you’re done using it, uninstalling is as simple as deleting the files you downloaded.

No Admin Rights Needed

You don’t need any special admin privileges to run this tool since it doesn’t leave entries in your Windows registry or store data on your computer. You can even pop it onto a USB flash drive and take it wherever you go!

User-Friendly Interface

The layout of NMEA Sentences Checksum Calculator is super minimalist, which means you won’t be overwhelmed by too many options. Everything you need is right there on one screen, making it easy to get started.

Calculating Your Checksum

You can manually enter your NMEA string in the designated area and hit the ‘Calculate’ button to check out the checksum. To verify that your checksum is correct, simply copy it into another panel and click on ‘Checksum’. If it's highlighted green, you're good to go! A red highlight means there’s an error.

A Few Limitations

On the downside, there isn’t a clear-all button for erasing fields at once; you'll need to delete each entry manually. Also, importing and exporting options aren't available.
