It’s time to get the conclusion of this Guidance, Navigation and Control post series.

Conclusion

To sum up:

• Navigation System (NS): Where are you?
• Control System (CS): How are you?
• Guidance System (GS): What are you up to?

And finally, “do not put the cart before the horse”. The cart is the guidance system, the horse is the control system. A good guidance without a good control is totally useless. A good plan is nothing without a good pilot. I’d rather fly in an aircraft with a good Stability and Control System and a poor Guidance System than the opposite. In the first case you might not reach your wanted destination, in the second case you will crash!
We live in an economic world with a lot of guidance and very little control. That is why the finance world totally collapsed, leading us to the current global crisis. More details in a future post…

3 parts are in this post because they are shorter:

• About the human pilot (with fresh news: man in an Unmanned Aerial Vehicle is for “soon”)
• About GNC wordings
• About the various control loops
