Control Systems 102: GNC, Guidance, Navigation and Control, Introduction

Posted by Harry Seldon on April 27, 2009

Guidance, Navigation and Control are often together. It makes perfect sense because all three of them depend on control theory and because they are the components of the software part of a Control System. But do you clearly know the differences between Guidance, Navigation and Control? I am going to explain them taking the example of an aircraft. In future posts I will take other examples such as a company, a country government or the go game. This series of posts is a follow up of Control Systems 101.

GNC

This post was quite long so I decided to cut it in several parts. Even cut in several parts, the point remains to consider GNC as a whole, it is not to make extensive explanations on each topic. Wikipedia would be fine for this, whereas it is not so good as far as the GNC topic is concerned. According to your comments, I may update Wikipedia with the little work made here.

The first chapter presents the Navigation System.

Here is the Table of Contents (TOC):

Introduction
Navigation
Stability and Control
Guidance
About GNC written GN&C or GCN written GC&N
About the human pilot
About control loops
Conclusion

    A visualization of chaos is given by fractals. I showed you the pictures of fractal trees taken during a walk at the Parc de Sceaux after a snowfall in Paris. But I had taken a few more pictures of the very beautiful French garden of this Park. A ...
