I read an article In one of the Electronic trade magazine some time
ago. This article was written by an engineer who had been evaluating
the GPS technology, chipsets and devices available at the time. One of
his hobbies was sailing, and he took the several GPS devices along on
a weekend sailing trip around some islands in the west indies.
Was "some time ago" prior to the removal of Selective Availability?
That is irrelevant as long as the system contains the option of SA.
How can you be sure that the SA is not activated tomorrow ?
Not at all irrelevant to Anton's anecdote, which you snipped. |
