Gazebo can be run in a _headless_ mode in which the Gazebo UI is not launched. This starts up more quickly and uses less system resources (i.e. it is a more "lightweight" way to run the simulation).

2. Open the SDF file for your target vehicle (e.g. **./Tools/sitl_gazebo/models/iris/iris.sdf** ).

The location of the world is defined in the **.world** file by specifying the location of the origin using the ` spherical_coordinates ` tag. The latitude, longitude, elevation must all be specified (for this to be a valid).
