Navigation is defined as the science of getting a craft or person from one place to
another. Each of us conducts some form of navigation in our daily lives. Driving to
work or walking to a store requires that we employ fundamental navigation skills.
For most of us, these skills require utilizing our eyes, common sense, and landmarks.
However, in some cases where a more accurate knowledge of our position,
intended course, or transit time to a desired destination is required, navigation aids
other than landmarks are used. These may be in the form of a simple clock to determine
the velocity over a known distance or the odometer in our car to keep track of
the distance traveled. Some other navigation aids transmit electronic signals and
therefore are more complex. These are referred to as radionavigation aids.
