ArduPilot/pymavlink

What it solves

Pymavlink provides a standardized way to communicate with and control unmanned vehicles (like drones and submersibles) using the MAVLink protocol. It bridges the gap between software applications and flight hardware, enabling developers to send commands, receive telemetry, and analyze flight logs.

How it works

It acts as a Python implementation of the MAVLink protocol. It includes a code generator (mavgen.py) that can take XML-based message definitions and generate protocol implementations for Python and other programming languages. The library also provides tools for processing and analyzing flight data logs, and allows for custom mapping of vehicle flight modes.

Who it’s for

This project is designed for developers and robotics engineers building ground control stations, flight analysis tools, or autonomous vehicle software that needs to interface with ArduPilot or other MAVLink-compatible systems.

Highlights

• Full Python implementation of the MAVLink communication protocol.
• Includes a source code generator to create protocol implementations for multiple programming languages.
• Built-in utilities for parsing and analyzing flight logs.
• Supports custom flight mode mapping for specific vehicle types via JSON configuration.
• Extensively used within the ArduPilot ecosystem for vehicle control and telemetry.
