GPS Inventor backs UK efforts to reduce risk of jamming
Article by: Darren Griffin
Date: 20 Feb 2014
Professor Brad Parkinson, the chief architect of GPS, has told a UK conference that satellite based navigation and timing systems need to be more robust.
The loss of spectrum, space weather events and the deliberate use of GPS jammers have all given rise to increased concerns about the availability of GPS services.
Speaking at the GNSS Vulnerabilities and Resilient PNT Conference 2014, Professor Parkinson proposed a three stage program that he has named 'PTA' which will Protect the signal and eliminate jamming, Toughen receivers resistance to interference and Augment the GPS signals with data from other satellites and ground based transmitters.
Tougher penalties need to be implemented for anyone caught using a GPS jammer. A recent case in point was where GPS technology being used toy aid landing at an airport in the US. Frequent jamming events were being observed and a three month investigation tracks the source down to a trucker who was using a jammer to stop his bossed monitoring him.
GPS jammers, whose use is unlawful, are readily available. The GPS signal is weak and all too easily disrupted and, with our ever increasing reliance on them for navigation and timing signals (used in banking) it's an issue that needs to be addressed, and done so quickly.

Considering not very old statement from the Ford CEO (even if "corrected" quickly) can cause some questions related with privacy...
He stated that Ford have knowledge about all its cars drivers behaviors and their position, speed, etc.http://www.cnbc.com/id/101323703
This was investigated and it was found that user, while starting the embedded GPS SatNav in ford cars, must give consent to this.
While he later denied that, stating that they are not actually collecting the data, and they are not forwarding it to the authorities, it is imaginable that they will provide data against the court (or other legal authorities) order without informing the user.
Therefore, I can understand the average Sam's who would like to visit his very close friend Kate without leaving info about it to his wife, Mary, who works at local police station 
As far as I know, the Ford is not alone with the ability and practice to track clients (such, even anonymized) behavioral data can be pretty precious on the market...
It is sad that there is no possibility for example to jam the onboard embedded device without jamming other users.
Of course, my comment relates to the private users only, the company's cars tracking (and jamming) is completely different story.
