GPS is a complex technology but understanding it can be quite easy if you take it one step at a time. This tutorial is designed to give you a good basic understanding of the principles behind GPS without loading you down with too much technical detail.
In the old days, not that many years ago, the technical side of navigation was pretty easy to understand. Magnetic compasses were simple objects, and map reading was a matter of basic orientation. Today you can't understand how navigation works without a degree in quantum physics.
So I will try and simplify it for you.
As a neophyte, don't get hung up on things like differential correction, GNSS surveying, dual frequency measurement and ionospheric or tropospheric deviation. Believe me no one cares if your plod-booster receiver runs at 7.6Dh or lower, so there's no need to feel inadequate. Concentrate on how the digital information is triangulated conceptually. Fortunately this is easy to grasp. The GPS chip comprises a new element, Creatium (C), not to be confused with the speed of light (C). When these collide, they excite multitudes of particles known as morons (m). At critical mess, the nuclear bisons---agitated beyond control---stampede into isotopes, providing stuff stash outsource integration with plug-and-play, point-and-shoot, drag-and-drop convenience. In short, datum emergence (as we experts say) is a result of morons excited by light/creatium, or e=mc (squared).
Hope this helps.
Gotcha

I find it very funny that you and James are both GPS fans. We call him our "High Tech Cowboy" as he often goes out with his GPS and maps riding trails. :-)

Actually I am NOT a GPS fan, I rather loath the things.......Marketing promoting consumerism in action I say! Even the GPS manual says....."learn to use a map and compass...." before venturing out...after all what are you going to do when the battery dies....*grin*
I don't own one, but do see their value in some applications.....navigating a strange city or pin-pointing exact lat and long.
Ciao
The way JAH uses his is pretty neat. He creates trail maps for his SAR buddies, and other horseback riders to follow. He also teaches courses on orienteering on horseback (def with compass and map) for various 4-H and other youth groups. Pretty kewl.
I've been teaching Sea Kayaking here and there for about ten years now, including marine navigation, dead reckoning and piloting.
The last post here was from an "Instructor Trainer" mentorship I'm taking part in...Spent a week on Georgian Bay (Lake Huron).
Talk to ya soon!
