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."

      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.

      Sorry. I knew that was confusing when I wrote it. I was referring to other things. I did not intend to imply that GPS is a right.

      I think we are far safer than we were 3-4 years ago

      I disagree. There have been some changes. I think most of the positive changes are in personal attitudes. There is no way that a terrorist is going to take over an airliner now. The pilots won't allow it, and neither will the passengers. Public opinion is (rightfully) such that I'd almost feel sorry for a terrorist who tried. People accepting responsibility for their own safety and the safety of others is a good thing. But the government has spent a lot of money with dubious improvements to real security while major security issues remain. One big example that has shocked me since way before 9/11 is the way air cargo is almost completely uninspected. There are so many ways this is dangerous.

      But there is a much bigger reason we're less safe. I think invading and occupying Iraq without legitimate cause (WMD, supporting terrorists, etc.) has led to massive resentment in the Arab world and has provided a recruitment poster for al Qaeda. The US has ignored it's own laws and international treaties by capturing US citizens and citizens of other countries, declaring them "enemy combatants" and insisting that they have no legal protection, either under the US Constitution or the Geneva Convention. Countless examples of graphic prisoner abuse in Abu Ghraib and similar Red Cross and Amnesty International reports from Afghanistan and Guantanamo Bay add to anti-US sentiments. So do the dead Iraqi civilians, currently numbering about 16,000 and counting. Then a US soldier is found guilty of the premeditated murder of an Iraqi teenager. All of this creates hatred for the US, and that is used to enlist terrorists. I'm all for killing terrorists, but this is creating three for every one that's eliminated, and that's moving in the wrong direction.

      Many people I've spoken to believe "It's better to fight 'em over there than fight 'em over here." The obvious flaw in that argument is the assumption that there is a constant number of anti-US terrorists. We need to understand that our actions are creating terrorism by drastically increasing anti-US sentiment around the world.

      I voted for the person who I believed would do the best job handling my top concern of security

      Security was a big issue for most people in the 2004 US election. It all boils down to what each person thought was most likely to provide security. I think it could be best summarized by the choice between "fight harder" or "fight smarter". I wish we had better candidates than those trotted out by the two party system.

      I just hope we can put the nastiness of the election behind us

      Me too. It was very divisive. I also hope we can regain some international respect in the process. Some people apparently don't think so, but we really do need allies to fight international terrorism.

    This is incredibly shortsighted, let me give you a good example: In the immediate aftermath of Hurricane Charley, cellphones, telephones and existing radio systems were down in the areas hardest hit, but amateur radio operators swarmed the area and deployed new antennas and crank up towers and tons of radios for the first responders. In addition to that they deployed this amazing technology called APRS for the salvation army and others that allowed the participating groups to track in realtime the location of all of their vehicles.

    Now, if your not familiar with APRS, it starts with a low powered radio, a GPS unit, and a device that hooks up to the GPS and the radio that transmits the GPS coordinates in digital format on the radio. Then, ideally, a central radio tower can hear these signals and develop a picture of where all the signals are based off of their GPS coordinates. Whats even more insane is that APRS has grown so much that satellites and even the international space station repeat and broadcast APRS signals!

    So if GPS were shut down first responders would lose a valuable emergency coordination resource. Not to mention the fact that some police/fire already have similar systems in place, though generally such systems are wiped out in disasters, hence the amateur radio operators who are at the ready to redeploy communications gear.

    If the US openly state that they have controls to shut down both GPS and Galileo, won't that make the services less interesting for time-critical services (like ambulances and firemen) to use?

    I mean, won't designers of systems for that type of services go: "But what if the GPS or Galileo is shut down? Then we need an alternative! Might as well not bother with GPS or Galileo and spend our money/time designing the alternative..."

    This would be a waste of a perfectly good system, in my opinion, but an understandable design decision for any designer who needs to be sure her design will work.

    There has never been doubt in my mind that for simple military reasons the US have had measures to shutdown the service. But the fact that they're openly advertising it seems to indicate to me that they will not hesitate to actually use those measures whenever they think it might help in the way of "preventing terrorists from using it". Nevermind the arguments by others in this thread for why that's fairly useless to begin with.

    That is called projection. As in projecting your faults on others. Yes, most of the European powers would indeed take possession and try to keep anything they won in War.

    If empire were an American desire Europe would have went through being territories all the way to US states by now.

    State-based imperialism has been shown ineffective. It's unwieldy, it doesn't really offer any advantages, and it's risky; when you attempt to retain dominance in an area through military means, sometimes people fight back through military means, and it's not always possible to paint the people fighting back against an invading/occupying force as the aggressors. Plus, you can only maintain state-based imperialism if you continuously control the state that runs the empire, and in a democracy like America this runs the risk of temporary local power transfers leading to your empire being disassembled.

    The important thing now is economy-based imperialism. There's no need to rule the world when you can just own it. The wave that's been building since 1950, and the wave of the future, is for empire to be economic in nature, for military force to be used only when necessary to support that economic empire, and for the states-- which are increasingly irrelevant anyway-- to be ignored except when they stand in the way of that empire's interests.

    Of course, occasionally America may resort to traditional, invade-and-occupy methods of imperialism to maintain its economic empire and ensure its spheres of interest. But this is usually not necessary, and only under certain circumstances is it the appropriate tool to use. Who on earth would try to invade or occupy Europe, anyway? Twice now in the last 250 years Europe has faced a rogue superpower trying to conquer the continent through military means, and both times it repelled and squashed that superpower against staggering odds. Only a very poor businessman would accept those odds even if there were a good reason.

    Nope, we know who has it right and reelected him. The War against Islamic Fundamentalism is the number one priority for our generation and Bush understands that. You and Kerry don't believe that, and were rejected for it. History will prove one our views correct, the question is whether those histories will be written in English or Arabic.

    Additionally, you are soon going to be in an economic war with nearly the entire world. History will prove what it always has, the large empires collapse when they get too greedy. Personally, I am working towards that collapse by not buy American products (as much as possible).

    Seeing as how your political philosophy has been on the wrong side of the major conflicts the US has been involved in lately (WWII, Vietnam, the Cold War/WWIII) the safe money would be on you being wrong yet again on WWIV on that basis alone.

    Umm. WWIII??? Whahahaha. Boy, not only do you parrot back the propaganda from your government perfectly, but you even proove the stereotype that americans are self-centered. There is no WWIII. The US beating up some helpless arabic countries does not constitute a world war.

    Yep, and the world noticed that and by everything I can tell greatly appreciated it. That generation of Americans has a lot to be proud of. However, it wasn't long before we started to burn through that good will. Maybe it's just me, but the burn rate seems to have gone up a lot in the last two years. However, American pride has not diminished in relation with the actions taken. I've always believed that pride is justified by actions, not vice-versa.

    The America of today is not the America of 1945. Using WWII as an example of our good intent only throws current events into sharper relief.

    We have no longterm designs on the Middle East.

    A telling moment for me was in the debates, when Kerry said it was important to demonstrate that we had no long-term designs on the Middle East. Bush made no comment. Probably because if he had, the obvious rebuttle would have mentioned the huge permament military bases we're building in Iraq.

    By the way, there is a narrow difference between outright imperialism and the pseudo-imperialism where you place a "soverign" but for all intents and purposes puppet government in power and tie the economy of the country to your own corporations while maintaining a massive military presence. The only people who are fooled by this difference are the ones doing it.

    In other words, if it is true that we (meaning the government) have no long term designs on the Middle East, we are a long way from proving it.
