In the United Kingdom the Royal Institute of Navigation
are issuing warnings on the vulnerability of GPS to loss of signal and
interference. The received GPS signal is so weak that any
interference could stop the GPS receiver completely.
With the GPS acting as a back up to normal navigational
methods this is not so important. However where navigation is 100%
dependent on GPS this could be catastrophic! Fortunately the GPS
does not produce an error signal so when it is not working it should be
relatively obvious.
