This documentation will guide you on how to set up a SITL (Software in the loop) on UBUNTU 20.04 LTS with PX4-Autopilot, QGroundControl paired with simulation software Gazebo 11.

Let's get started by opening up the Terminal on your system and entering the following commands:

##YOUTUBE TUTORIAL

cd ~
git clone https://github.com/PX4/PX4-Autopilot.git --recursive
bash ./Tools/setup/ubuntu.sh

Step 2 - Install Gazebo 11

cd ~
curl -sSL http://get.gazebosim.org | sh

Visit Gazebo website for Alternative installation

The terminal may prompt you to install some python modules during this installation,install it for example

pip3 install --user empy
