My dad, Roger Easton, invented GPS. See my website www.gpsdexlassified.com

That’s pretty cool. Your dad has a Wikipedia page.

For those who want to look it up, the correct link is www.gpsdeclassified.com

Looks like a fascinating book!

I met your father many years ago, maybe around 1987 or so.

Fascinating fellow. I asked him a lot of questions about the GPS after he mentions what he had done when I asked him what he had done before retiring.

I spend a lot of tie in the boonies, in our Unimogs, on our Rokon Trailbreaker and Skidoo Expedition.

I use all available sources of information about where I am going.

Books, GPS, Topo maps,both modern and old, any other paper maps or online maps I can find.

The more info the better.

On the trail I use GPS and folding maps.

If in the Unimog(s), laptop computer with DeLorme GPS receiver and topo maps, sometimes satellite images.

Ham Radio APRS at times too.

Thank-you for letting us know. FR’s connection to history never ceases to amaze me.
