⁠PX4 SITL - SIH (Lightweight Simulation)

Run PX4 autopilot simulation with a single command. No build tools, no dependencies.

⁠Quick Start

docker run --rm -it -p 14550:14550/udp px4io/px4-sitl:latest

Open QGroundControl⁠ and fly.

⁠What's Inside

A pre-built PX4 autopilot running the SIH (Simulation-In-Hardware) physics engine. SIH runs the flight dynamics directly inside PX4 as a C++ module with no external simulator needed. Headless by default.

• Interfaces: MAVLink (UDP 14550), uXRCE-DDS (ROS 2), PX4 shell
• Platforms: linux/amd64, linux/arm64

⁠Configuration

Set the vehicle model with PX4_SIM_MODEL:

docker run --rm -it -p 14550:14550/udp -e PX4_SIM_MODEL=sihsim_airplane px4io/px4-sitl:latest
