GPS
has revolutionised navigation, delivering accuracy that was undreamed of,
even a few years ago. In combination with a chart plotter, autopilot and
radar, it makes a vast range of navigational data available.
But, to get the most out of it and avoid the pitfalls, it pays to know
something about the technology involved.
This programme explains how electronic navigation works and how to use it
to best effect on your boat.
If you are new to boating we advise you to first view our programme
"Understanding Navigation" This deals with the basics you will
need before moving to more complicated electronic navigation systems.
