GNSS-Parser-Reproducer

This project is designed to record and replay GNSS serial data, specifically handling NMEA and UBX messages.

It consists of three main scripts: record/src/record.py, replay/src/replay.py, and replay/src/serial_emulator.py.

Features

• serial_emulator.py: Emulates a serial device using socat.
• record.py: Reads data from a serial device and saves it to a JSON file.
• replay.py: Reads data from a JSON file and writes it to a serial device and, if desired, it displays a GUI to visualize the vehicle.
• decoded_messages: Decodes NMEA messages to extract latitude, longitude, and heading of vehicle for the GUI.

Requirements

• Python 3.x
• pyserial
• socat (for serial emulation)
• nodejs (for the GUI mode)
