implemented over the next four years, I suspect GPS packaging and
costs will be very different from what we see now. (Current
nonmilitary GPS units are able to indicate where you are to about
400 feet due to scrambling; without the scrambling, you can locate
your posistion to about 30 feet.)
I did read about the change coming, thanx for the info on
the newsgroup. I know there's ways to compensate for the error
built in, like GPS used on ships and planes, but thse units are out
of my price range, and of couse, to heavy for hiking purposes.
