I had a question for the GPS archaeologists they might be able to
answer. Just before President Clinton left office he passed a law
which removed the "scrambled" signal applied by the US Defense
Department to GPS satellite transmissions, purportedly, so that
missile silos could not be targeted accurately, with most GPS
receivers.

Does anyone know if that "option" as I understand it (once turned off
in the early 1990s for "Desert Storm" and many veterans mother bought
GPS to send off with their now veteran I read) has been reintroduced
now that (gee I thought of this now?) the US Congress declared "War on
Terrorism"? In government one of the first accurate uses with setup
differential transmitters was in the Bay of Fundy, New Brunswick,
Canada, with the highest tides in the world so that fishing boats,
ferries, etc., had more accurate locations in a pretty regularly foggy
environment.

Have the Iranians one set of calculations and the British Navy another set?
