NMEA sentences checksum calculator
NMEA sentences checksum calculator is a Java-based software application designed with a single goal in mind: to help you calculate and verify NMEA sentence checksum used with GPS devices.
Each NMEA message starts with a dollar sign. At the end of the sentence, the asterisk is followed by a checksum represented by a two-digit hexadecimal number. The goal of the utility is to calculate the exact two digits found at the end of the NMEA string.

The program comes wrapped in a portable package which can be deployed on your system by skipping the installation steps. You only need to run the EXE file in order to gain access to the app’s GUI.
Uninstalling the tool can be done by deleting the files that you have downloaded from the Internet. It is important to mention that you can run the utility without administrative privileges, as it leaves no entries in the Windows registry and configuration data in your computer. Copying it on a USB flash drive or other devices is also possible.

There are no intricate configuration settings hidden under its hood so you can easily get used to working with it.
NMEA sentences checksum calculator offers you the freedom to manually enter the NMEA string in the dedicated panel and press on the ‘Calculate’ button in order to check out the checksum.
In order to verify the integrity of the checksum you may copy the calculated value to a special pane and press on the ‘Checksum’ button. If the value is highlighted green, the checksum is valid, while red signals errors.
On the downside, the program doesn’t allow you to clear all fields with a single button so you need to manually erase the entered strings. Plus, there’s no support for importing/exporting options.
All things considered, NMEA sentences checksum calculator delivers a basic feature pack for helping you calculate and verify NMEA sentence checksum.
