How a sailor helped invent today's GPS navigation... In 1985!

Amazing story and well worth the long read. A navigator on a TransPac race used a satellite twice daily fix, along with celestial navigation, to help invent the first in car navigation system, and sold a number of thousand of them

Some of the technology developed then is still used for accuracy in GPS mapping today. Amazing when one learns that the data they used were cassette tapes.

If your attitude resembles the south end of a bull heading north, it's time to turn around.

Yeah, I too saw that article and found it fascinating. The fact that they could actually sell a car navigation system that was basically based on dead reckoning is pretty amazing.

Pretty cool, too, that it was born on a TransPac run while thinking about a better navigation system.
