NmeaGenerator_pi is an OpenCPN plugin that generates, injects, and simulates NMEA 0183 data streams without requiring physical navigation hardware.
The plugin provides tools to:
- Send custom NMEA sentences manually
- Create common navigation messages through a simplified user interface
- Simulate vessel and/or AIS target in real time
It is intended for OpenCPN development, navigation software testing, AIS/GPS simulation, instrument validation, and NMEA data analysis and debugging.
Complete documentation is available in the manual.
