........I met an interesting
man who can be called the "foster father of GPS."



There was an interesting squib (the 'Trailing Edge' column) in the MIT
Technology Review December '04 issue that may have referencd this person.
No Smith mentioned, though. :-) These two fellows cobbled up a quick unit
to receive the signals, factor in the doppler shift, and identify the
location of the transmitter - the satellite. Their boss said "Oh, that's
nice". A few months later he got back to them all torqued up (having
obviously mentioned this doohicky to someone), and asked them if they could
reverse the process -- receive the signals, and identify the location of the
receiver. Read it at
