Trump Signs Order To Test Vulnerabilities of US Infrastructure To GPS Outage (reuters.com) 165

U.S. President Donald Trump on Wednesday signed an executive order directing U.S. agencies to test the vulnerabilities of critical infrastructure systems in the event of a disruption or manipulation of global positioning system services (GPS). From a report: GPS is critical to a variety of purposes ranging from electrical power grids, weather forecasting, traffic signals, smartphone applications and vehicle navigation systems. The order said "disruption or manipulation of these services has the potential to adversely affect the national and economic security of the United States."

    There are too many nations testing their ability to jam or block GPS signals. So many things are dependent on them, and it works so well, they haven't used an alternative. Need to make sure things don't start crashing if the GPS signal is blocked or corrupted.

      Luckily there are currently multiple competing GNSS, GPS isn't the only game in town: Galileo has recently achieved a full constellation, Glonass has recently re-established theirs fully, and BeiDou's constellation is in a complete enough state to achieve global coverage.

      Nearly all current hardware (e.g.: Smartphones) are capable to talk simultaneously to the 4 major GNSS constellations.

      For the systems that only use GPS for accurate time input and not actual position, there might be even more extra alternat

            I currently work in large vessel navigation. They pretty much absolutely depend on GPS for their day to day operations. Yes, there are ways to operate in a GPS denied environment (I also do submarine navigation), but it's a lot of work that most crews, especially the poorly trained merchant crews, have lost the skill to do so.

        Unfortunately, they all use similar frequencies, and are all similarly easy to jam -- the signal at a GPS receiver is so weak that it is literally below the noise floor, so it's exceptionally easy to jam it.

      One would hope this would signify he is finally wading into the infrastructure repair he promised during his campaign (one of the few parts of his platform you couldn't argue with). US communication, utility, and transportation infrastructure is either horribly aged or under capacity and definitely needs improvement. Unfortunately the only kind of infrastructure he's really put any effort into so far is of the border wall variety.

      You shouldn't be. Infrastructure is a big concern of his, including technical infrastructure. On the campaign trail, he talked a lot about technical vulnerabilities as a national security issue. The vulnerability of (and over-reliance on) GPS has long been a concern of mine. This kind of audit is way overdue. Hats off to Trump on this.

        Politicians say a lot of things on the campaign trail. You see what they actually care about when you see what they spend their political capital on once they're in power. And infrastructure is a pretty easy political sell on both sides of the aisle. So where's all the activity been for the last three years that shows he actually cares about it?

          • I hope you're being sarcastic. Rebuilding a few dozen miles of existing wall is political theater, not infrastructure. Infrastructure is the stuff that gives you the ability to do other stuff. Roads. Plumbing. Power and communication systems. A wall just sits there.

              I hope you're being sarcastic.

              Of course. A wall at the border is a waste of money, especially if the goal is illegal immigration, since most illegal immigration happens in airports (people overstaying visas). The southern border is simply the most visible. I especially oppose taking the money from DoD construction budgets to pay for it. If the DoD really doesn't need that money, use it to improve VA infrastructure.

                I wish. Don't forget your /sarcasm tags - the number of people who honestly believe and spout ridiculous nonsense has been increasing at a dismaying rate in recent years - and not just among Donald's fan club.

    • Yes, exactly what I was thinking. I wonder who it was whispering this in his ear, who also was savvy enough to make him think it was his idea? Trump isn't smart enough to understand everything GPS is used for so someone else had to have told him.
    • I don't expect it to be much of a decision, but something that will not have negative consequences for him. (Unless it actually disrupts GPS for the whole public)

      Trump only cares about himself, not the nation or other people. If it isn't about him and it isn't about people who is against him, he would blanket sign it.

      No we really don't. aviation navigation systems have not nor are being "converted" to GPS "instead" of radar. They have augmented the existing systems with radar.

      There are many critical services which depend on GPS. Navigation in any form is not one of them as all retain fallback strategies.
      Time sources on the other hand are far more important with a lot of critical infrastructure highly dependent on accurate time.

  • Remember the Gulf war? When the military lock on the GPS was lifted and the civil GPS got as precise as the military one? That was done only because many soldiers in the Gulf region only had a civil GPS. The USA already knows how dependent they are on their system.
    • That was done only because many soldiers in the Gulf region only had a civil GPS.

      Whereas, it the same situation happened today, those soldiers might be relying only on civilian smartphones.
      It GPS was locked, any modern smartphone would simply failover to another of the majors GNSS systems it supports (Galileo, Glonass, Beidou).
      The users wouldn't even notice that GPS isn't available.

      • by Strider- ( 39683 )

        Here's the thing: Without GPS (or GNSS in general), those smartphones will cease to work. The mobile phone system is absolutely dependent on GPS for synchronization and timing of the on-air signals; this is what allows them to pack the cells in so densely. In order for CDMA to work (the underlying transmission technology used in LTE, 3G, and the previous techs) there needs to be precise timing of the signals so that the pseudonoise cancels itself out.

        So, if the timing goes away, the whole system stops worki

        • So the question remains - what is the GPS needed for? It's not like cell towers wander around - once they're built, they stay where you put them. Maybe you use GPS to precisely determine their initial location, but then you shouldn't need any further input for the life of the tower (barring major geologic activity)

          The phones themselves certainly don't need GPS - as can be easily proven by disabling the phone's GPS. All they care about is the signal strength, and will quite often connect to a further towe

            It has nothing to do with the position of the tower, and everything to do with timekeeping and signal synchronization. The modulation techniques used to allow multiple users on the radio channels (CDMA,OFDMA, etc...) used in all the modern cellular standards require absolutely precise timing so that the technique works. Without the precise timing, different transmitters will get out of sync and will very quickly start to interfere with each other. This is why the pico cells that some of the cellular provide

          • Essentially, GPS is an effectively-free (for users), extremely-high-precision timebase. This means more than the fact that you can know the time very well; it provides an extremely stable frequency standard, with extremely little phase noise, for use for calibrating other clock sources -- like the ones used to generate the EM frequencies used for communicating with cellphone towers. The drift of a GPS-disciplined clock can be as little as 1x10^-13 -- one second in 10 billion/day. (Though in this situation

        And they would not really know which system is failing if they only support two ...

        GPS is not locked as in not available, it is simply displaced by a known amount for military GPS and an unknown by civilian. However with a earth bound reference point, that is mood ... hence GPS was "unlocked" more than a decade ago.

    • by Strider- ( 39683 )

      Well, they turned off Selective Availability for that conflict. GPS has evolved significantly since then, so mil GPS can still be more accurate than civil GPS (for what it's worth). It's primarily due to the fact that the primary error source in GPS comes from the ionosphere, and how much it affects the travel-time of the signals passing through it. By receiving both the civilian L1 frequency, and the military L2, the receiver can measure and calculate the effect of the ionosphere, and factor that out, res

      • Of course, most of the time when you're dropping a 2000lb JDAM, a few feet one way or the other doesn't make much of a difference.

        We are seeing guided weapons that are so precise that they could register a kill with a 2000 pound laser guided sack of sand. They don't need GPS for this, just a good ID on the target and someone to light it up with a fancy laser pointer.

          Most warfighting has moved away from laser guided munitions, as they're far more expensive. A JDAM kit costs something like $20,000 and can be bolted to the ass-end of a conventional 2000lb iron bomb. No muss, no fuss. The laser guided munitions, of which you speak, are far more complex, and require optics at the front of the bomb to track the target, and the computer/control surfaces at the rear. Add to this the fact that a laser-guided munition requires your target designator to stay lit while the weapon

  • It is a little unclear in the article whether we are talking about navigation (i.e., global positioning) or more narrowly about precision timing.

    Probably the most crucial application of GPS (in terms of economic value) is the widespread dissemination of a standard time basis. There are other ways of doing the latter, which the article alludes to. One is the WWV radio signal from NIST, which oh-by-the-way Trump wanted to kill in his FY2019 budget [slashdot.org].

  • Threats and vulnerabilities are actually two different things. A threat is something an enemy hopes to achieve, like causing the traffic systems of a country to collapse. A vulnerability is a candidate mechanism for accomplishing a threat, e.g. disabling satellites or jamming their signals.

    It seems like concerns on the failure of GPS comes up every so often, ever since we started to use it. Or, rather once we started dismantling the older systems we used before GPS. These would be things like Loran, VORTAC, inertial navigation, and the equipment and training for celestial navigation.

    Loran was worldwide, not all that accurate, and is no longer functional.
    https://en.wikipedia.org/wiki/... [wikipedia.org]

    VORTAC is still functional but with range limited to about 200 miles it's only useful near developed coastlines and on paths over land.
    https://en.wikipedia.org/wiki/... [wikipedia.org]

    Inertial navigation will work without outside radio signals but it can drift over long periods/distances and so needs something to re-align itself once in a while.

    I remember reading about how the US Navy stopped requiring all officers the the navy academy to take celestial navigation. They still required some enlisted ratings to learn how to navigate by the stars and as I recall officers still had to have a very basic introduction to celestial navigation, mostly to know that it was possible, that others would know how to use it, and as something of a history lesson. They reversed this policy and again required all officers to learn celestial navigation after some scares on GPS failure. Every Navy ship and aircraft over a certain size will have the necessary charts and equipment for celestial navigation. I'm no sailor but it sounds like many recreational and commercial sailors will learn celestial navigation, because getting lost at sea is bad.

    Here's what I expect to be the future of navigation, automated celestial navigation. If the sky is visible then the sun, moon, and stars, can be used to find one's location. Add in things like a magnetic compass, barometric altimeter, and accelerometers for inertial navigation, and the system should be quite accurate. There's software to do this for common smart phones. Give the device better optics than a common iPhone and it can "see" the sun through the clouds and find stars even under a bright noon sun. This kind of navigation cannot be jammed, and given how inexpensive and powerful computers are today this should be quite affordable and easy to use.

    Celestial navigation, even with computer aid, is not likely to be as accurate as GPS is now but it should be more than enough as a backup for people to use for navigation over the sea, and maybe even enough to find one's location in a car if one can safely assume the car is on a road and has accurate maps to use. Once an aircraft is over land, or a ship close to shore, then systems like VORTAC, and just plain looking out the window to find landmarks, should get a person where they need to be. I remember someone posting on Slashdot not too long ago how people would navigate while flying over the mountains if their primary navigation failed. The plan was to find a mountain peak, look for flowing water, follow the stream as it flowed down the mountain, eventually the stream will lead to a city or settlement which will have a strip to land. Following water flowing to the sea might not be ideal but it's better than many alternatives.

    We can test how robust GPS is but there needs to be a discussion on a backup. I believe this will be a combination of celestial navigation and inertial navigation, something a $500 smart phone is able to do with very high accuracy.

    Side note: I do wish people would separate the US GPS from other similar systems by using it's original name, Navstar. Navstar is just one GPS among many. Loran is a GPS, as is Russia's GLONASS, and the European Union's Galileo. I realize this is likely a lost battle, it still bothers me though.
