It can also be used for multi-vehicle simulation and is commonly used with ROS, a collection of tools for automating vehicle control. The following simulators work with PX4 for HITL and/or SITL simulation.Ī powerful 3D simulation environment that is particularly suitable for testing object-avoidance and computer vision. The other sections provide general information about how the simulator works, and are not required to *use* the simulators. Information about available simulators and how to set them up are provided in the next section. PX4 supports both *Software In the Loop (SITL)* simulation, where the flight stack runs on computer (either the same computer or another computer on the same network) and *Hardware In the Loop (HITL)* simulation using a simulation firmware on a real flight controller board. It is also a good way to start flying with PX4 when you haven't yet got a vehicle to experiment with.
> **Tip** Simulation is a quick, easy, and most importantly, *safe* way to test changes to PX4 code before attempting to fly in the real world. You can interact with this vehicle just as you might with a real vehicle, using *QGroundControl*, an offboard API, or a radio controller/gamepad. Simulators allow PX4 flight code to control a computer modeled vehicle in a simulated 'world'.
