U.S. Makes Plans for GPS Shutdown

sailforsingapore writes "Apparently, President Bush is drawing up plans to disable sections of the GPS network in the event of a terrorist attack. The rationale seems to be that it would prevent said terrorists from using the GPS system to direct some sort of attack. The plan would shut down access not only to the GPS satellite network, but projects like the EU's Galileo. Ironically, this comes alongside the President's plan to strengthen the GPS network against deliberate jamming."

    The ability to selectively disable the network has long been a feature though usually it's spoken of in terms of disabling it over a (non-USA) battlefield. The govt. would be stupid to do this in all but the most serious emergency and then only for the shortest possible time.

    I wonder what the per-hour or per-day economic impact of disabling GPS over a heavily poplulated USA region?

    A decent number of aircraft/airports that use GPS approaches would have to go back to more primitive instrument landings (more delays); many trucking/shipping companies rely on GPS for tracking goods. Then there are surveyers and agriculture and such that may use GPS augmented with some local beacon for high accuracy.

    What other key economic uses of GPS are there?

    Imagine some terrorist group is launching a dozen of home-made of cruise missile towards Washington. Bush has every reason to shut down the GPS. It makes sense to ask EU for a favour to shut down Galileo temporarily.

    The problem is the Bush Administration is just so arrogant. The Pentagon has plan to do whatever, regardless of what they say they would or wouldn't do. I don't have a problem with this. But, that does not mean it is rational to threat the supposely allied EU countries for an attack of Galileo... Let's turn the table around.

  14. "Terrorists" by Afty0r · · Score: 5, Interesting

    Terrorists tend to be very clever, sly and intelligent people. They work with limited resources, frequently in enemy territory against a much larger force.

    Terrorists will not rely on GPS.
    The military is increasing its' reliance on GPS.
    therefore
    Shutting down the GPS will have no negative effect on the terrorists, but will hamper the military (and probably civil emergency efforts too).

    Finally, if the terrorists do mount an attack on us that somehow utilises GPS, it is unlikely we will know about it until after it has happened.

    Yes, you do, because that's way more important to the US than the impact of a terrorist attack. You need to have friends if you want a healthy economy, and a healthy economy is of much bigger importance on the average person's life than preventing terrorism.

    Unfortunately, people have a really skewed perception of risk.

    On 9/11 , about 2800 people (exact number is still unclear) suffered a terrible death in the terrorist attacks. Yes it was horrible. No, we don't want it to happen again.

    However, the current measures taken by the US government are going way too far, it's not worth reducing freedom for in any way whatsoever, the risk of being killed in a terrorist attack is extremely small. Yet, somehow, the perception of this risk is inflated enormously.

    To put things in perspective, last year there were 41,600 traffic deaths in the U.S. (15,700 alcohol related).
    It seems clear to me that unsafe driving and DUI is a MUCH bigger risk to the US people than a 9/11 style terrorist attack.

    The amount of money and effort spent on "the war on terrorism" is way out of proportion in relation to the risk involved. At the same time, I hear nothing about a "war on unsafe driving" or a "war on DUI", on the contrary, the government even seems to be promoting the use of SUV's which are proven to be more unsafe then 'regular' cars.

    WAAS was demilitarized some time ago. This allows for much greater accuracy.

    I work in the Testing & Evaluation of WAAS. WAAS and Selective Availability are not the same (or opposites). WAAS was never "militarized".

    When Clinton ordered for the switch to be flipped (so to speak), what was done was the disabling of Selective Availability, which was a purposeful degradation of the civilian GPS signal (L1). The military had (and still has) a second (encrypted) signal that a military receiver must have a key to properly use (L2). Using that signal enhances their accuracy, whether or not Selective Availability is active.

    WAAS (Wide Area Augmentation System) is something else. WAAS uses Geostationary Satellites to enhance (augment) GPS accuracy & precision in the USA. Not all GPS receivers use WAAS. Accuracy of a WAAS receiver is increased in either case (that is, with or without Selective Availability) relative to a non-WAAS receiver, but there is a noticeable difference from SA.

    Not all GPS receivers use WAAS, but Selective Availability has been disabled, which affects all GPS receivers.

    You (like many others in this thread, apparently) don't know how GPS works. There are a few points (not necessarily yours) that I'd like to touch on.

    Our military will still be able to access the network, but civilian units will not. Others can't jam us, but we can remove their access. Even differential GPS won't help in that case.

    The system was originally designed with this ability in place, as well as an accuracy restriction on civilian units, which was removed in the mid '90s. That restriction can be put back into effect at any time, however, just as the removal of service can be activated.

    A few posts back, someone mentioned "black market" units that would offer military access during such a blackout. Those that exist do not work (to my knowledge): each military GPS is coded to the network, and each unit has a unique code to access the network. While I do not have sources at hand, I recall that attempts to spoof such codes were anticipated and protected (unlike, for example, MAC addresses).

    As for private industry making GPS "10 times better at a 10th of the cost", it would never happen. The cost of designing, building and putting up 24-30 satellites orbitting at 22,000 miles and then maintaining them, as well as integrating all the security features would prohibit profit anywhere in the near term, even if users were charged a subscription fee. That is why its a great government project: people love it, but a decent profitable business model really isn't available for it.

    And as for the "government taking away our rights" argument, well, GPS isn't your right, especially if the government wants to take it away to protect you from attack. Oh, and as far as tax money, it's not yours, it's the government's. That's why it's TAX money; they don't owe you access to every system they build with it, though you are entitled to know what they spend it on. Hopefully, in more cases than not, it will be projects that help the citizens of the country, directly or indirectly. Even if GPS were available to the military only, it would still be helping us indrectly as taxpayers. This in no way means that we are entitled to access to GPS, or that it is a"right" - it most certainly is not. Neither is driving a car or flying an airplane, incidently, as some would suggest.
