1.1.1. What is Navigation?

Definition of Navigation in Real Space

The word navigation is originally a seafaring term. Navigation describes the process of estimating one's present position based on various tools. In earlier times wind, tide and currents acted as navigation instruments and today there are maps, magnetic compasses and even satellite-guided GPS systems that are used as navigation instruments.

According to (1998), good navigation tools provide answers to questions like:

• Where am I?
• Where can I go?
• How will I get there?
• How can I get back to where I once was?

Where am I?

Where can I go?

How will I get there?
