## Moving Platform
<Badge type="tip" text="main (planned for: PX4 v1.16+)" />
[Empty world](#default) with the addition of a flat moving platform, to simulate drone operations from moving vehicles like ships or trucks. The platform is controlled by a plugin which is included in the world. The platform is at a height of 2m, so place the vehicle on it with:
```
PX4_GZ_MODEL_POSE=0,0,2.2 PX4_GZ_WORLD=moving_platform make px4_sitl gz_standard_vtol
```
The plugin can be configured with the following environment variables:
- `PX4_GZ_PLATFORM_VEL`: Platform speed (m/s).
- `PX4_GZ_PLATFORM_HEADING_DEG`: Platform heading and direction of velocity (degrees). 0 = east, positive direction is counterclockwise.

:::tip
The moving platform plugin can also be used within other worlds.
For more information, see the plugin [README](https://github.com/PX4/PX4-Autopilot/blob/main/src/modules/simulation/gz_plugins/moving_platform_controller/README.md).

## Model Specific Worlds {#model_specific_worlds}
Some [vehicle models](../sim_gazebo_gz/vehicles.md) rely on the physics / plugins of a specific world.
