# Satellite: Controlling a Satellite Path

## Introduction

Model a satellite with a combination of 3D mechanics and block-based control logic. The satellite is launched from the Earth's surface with a launch sequence. Then a control logic subsystem adjusts altitude and velocity via thrusters. The Wolfram Language is used to design the parameters of the control system.

In order to get the full experience of this example, you need the following:

These pages show an overview of the example. For the full example, open the accompanying notebook Satellite.nb.

## Design Controller

Compare different controller options by the altitude and energy expenditure.

## Visualize Trajectory

Visualize the satellite using Wolfram Language functionality for 3D graphics. The images show the satellite path with and without controller.

These pages show an overview of the example. For the full example, open the accompanying notebook Satellite.nb.
