NMEATOOL+ 1.05

NMEATOOL+ by Jan Roskamp is a focused utility for working with NMEA data from GNSS and marine electronics. It helps you capture, inspect, and understand live or recorded NMEA sentence streams so you can diagnose issues faster and validate device behavior with confidence.

With a clean, no‑nonsense interface, NMEATOOL+ lets you:

• Connect to NMEA sources over serial/USB or network sockets
• Monitor raw sentences in real time with timestamping
• Decode and visualize key fields for common talker/sentence types
• Validate checksums and highlight malformed or out‑of‑range data
• Filter, search, and isolate the traffic you care about
• Log sessions and export data for analysis in other tools

Whether you’re integrating new sensors, troubleshooting installations, or learning how NMEA messaging works, NMEATOOL+ streamlines the process. It reduces guesswork, surfaces signal quality and formatting problems quickly, and provides the visibility needed to keep navigation and telemetry systems running reliably.

NMEATOOL+ is developed by Jan Roskamp. The most popular version of this product among our users is 1.0. The name of the program executable file is NMEATOOL.exe.
