Thanks Frank. I didn't want to be inundated with junk email from them for the privilege of reading the article.
Any system which utilizes such a narrow frequency band is subject to jamming. Widespread jamming requires a series of powerful transmitters (or just one). No big secret there.

Brad, you wrote:
"The Financial Times is subscription access only. "There's "fine print". If you register, you can get access to 8 articles a month for free. So to read the article, follow the link and register:

Alternatively, you can get at it, without registering, directly via Google News (though this probably varies by country). Go here:
https://news.google.com/
Then type 'Financial Times GPS' in the search box (or 'GPS site:ft.com') and search. It should be the first on the list of results. The full article title is "GPS pioneer warns on network’s security". After a few days, you may need to search on that full title.-FER
