Oh! Dear! Oh! Dear Oh! Dear! Good article
Apparently any jammer can have a jammer, and not only use it to jam their own
GPS systems, but could sit in the middle of the City of London and jam the
Stock Exchange. Apparently the algorithms used by the big investment dealers
are timed, audited and controlled by GPS systems. Just imaging what would
happen if it all got jammed. Speculation would run ripe for freebies. I must
watch my investment portfolio. I can see the makings of a book here...:-)
Some good stuff in El Reg today....

Critical infrastructure and emergency services need a satellite back-up
The technology is also widespread in financial services, with transactions
often driven by algorithmic trading, which requires timestamps at millisecond
to microsecond level. This form of precision timing also requires traceability
for audit purposes.
Charles Curry, founder of GPS resilience company Chronos Technology and
contributor to the report, told El Reg: “There is no difference in my mind
between a cyber attack over the internet and a cyber attack using GPS-jamming
technology. It’s something that North Korea has been doing for some time, as
well as Russia. What is to stop someone from switching on a high power jammer
in central London and taking out the financial services sector?”
He said the government must act to lead in putting a back-up system in place,
as simply using legal deterrents to prevent jamming is not enough.
Under the Wireless and Telegraphy Act (2006) it is an offence to deliberately
transmit within the GNSS frequency band without a licence or exemption notice.
So the use of jamming devices is an offence – but possession of a device is
not. "This means that courts have to prove intent to use, which can be
difficult" said the report.>>>end of quote
