A general GPS tech article, rather than a mapping-related one, but I thought it
might be interesting anyway.
IT WAS just after midday in San Diego, California, when the disruption started.
In the tower at the airport, air-traffic controllers peered at their monitors
only to find that their sy

what if it was intentional (signal-jamming experiment)? like what North
Korea is doing to South Korea.

They were not just jamming the GPS signals, if you read it all he was jamming
all communication channels to test if the two ships could work together.
Of course other things went down, eg phones.. Because they were also jammed to
stop the sailors using phones to call ship to ship..

GPS is more and more needed but the ATM's themselves do not have gps units..
Unless they were mobile ATMS..
ATMs are using GPS because of the timestamps simply because atomic
clocks are very expensive to install on each ATM. Personally, I find
it interesting because they found a use of GPS signal other than
positioning. However, I felt a certain degree on uneasiness for our
increasing reliance to GPS s
I really have second thoughts on this issue, you dont care what the machine
time is you care the server time.. The next issue is that there is not a
single article about ATM's failing in San Deigo in a mass scale in 2007.. That
would have been big news..
The guy seems to be real, but the articl
well, with the Philippine ATM setup, jamming GPS won't jam ATM machines in
Pinas.
I don't think there's a correlation with the ATMs and clock jamming, out of
sync time for machines will only be a reconciliation problem (the payment
back-office side) of banks but ATM transactions won't be affected.
