NATO Exercise Banned From Jamming GPS

judgecorp writes "A major NATO exercise off the coast of Scotland has been ordered to stop using GPS jamming technology after complaints that to do so would endanger the lives of fishermen and disrupt civilian mobile phones. The exercise — called 'Joint Warrior' — planned to disrupt GPS for 20 miles around each warship"

      Not at all. The effect jamming has on GPS is already well established and can be reliably reproduced in a lab/classroom environment - the receivers mostly just cease to work. Also nothing screams "I am exactly right here" quite like a jammer does, any half decent rack of ELINT gear will locate it within a very short space of time.

      A major military exercise... and they do not close those waters for the week or two these drills last?

      Civilian ships should stay the hell out of there. Stay well away from those war ships, they're in exercise, and may perform unpredictable maneuvers. There may be small craft out there. Projectiles flying around.

      If a ship comes within GPS jammed range then they're way too close to begin with I'd say. Yes this may cause some inconvenience to some fishermen or other seamen, but the ocean is big. Plenty of other places to sail to.

      So if your ships can readily navigate without GPS , then you can be pretty sure that all other military vessels will be able to do the same.

      So this is not a military exercise in the normal sense, this exercise is obviously targeted at military actions against civilian populations, where GPS jamming comes into play,

      What a load of rubbish.

      Near-fleet GPS jamming has nothing to do with ship navigation. Navies have been navigating ships without GPS for several hundred years. GPS jamming is to decoy incoming missiles which use GPS as ONE OF the methods of target location.

      Civilians, on the other hand have no critical dependency on GPS. Its largely a toy for the day to day user and a convenient (but non critical) aid for the traveler.

      The GPS bands are no where near satellite TV bands.

      GPS satellites broadcast at the same two frequencies, 1.57542 GHz (L1 signal) and 1.2276 GHz (L2 signal).
      Satellite TV uses the C-band frequencies of 5.4 GHz band (5.15 to 5.35 GHz, or 5.47 to 5.725 GHz, or 5.725 to 5.875 GHz, depending on the region of the world).

      Therefore it seems highly unlikely GPS jamming is the cause of any significant TV reception problems.
      G-Band (aka C-Band Radar) sits right in the middle of the Satellite TV band, and that is the likely source of any TV interference.

      Some reasons I can think of;

      a) Lots of soldiers have civilian gear as well. E.g. iPhones. You don't want them to have the opportunity to cheat. You do want them to use the gear in the way that they might without GPS so they have the feel for how it would be.

      b) Lots of systems are doing automated switch over; it may not be possible to properly activate that mode in the presence of GPS. E.g. if you have a system which does GPS navigation normally and then switches over to inertial navigation, you want to act as if there was a real GPS jamming.

      To be frank, anybody, military or otherwise who's operating GPS gear without a working fallback is irresponsible. What they should do is introduce safety regulations which say so and then give a very large fine to fishermen who complain next time. That will reduce the discussion.

      You assume that the military exercise actually benefit society more than those fishermen.
      Thing is that all of that exercise is funded by tax money and those fishermen pay that tax.
      I am willing to fund the military to ensure that I will have my freedom. If the own military starts to restrict my freedom then I don't care if it is the military that I pay taxes to that causes this or if it is a foreign military force, the end result is the same.

      So yes, unless you live in a military fascist state (This is not hte case here.) then you should expect the military to exersice without disrupting the ordinary civilian life because the only reason they get funding is because civilians don't want their ordinary life to be disrupted, if they can't do that then they are not doing their job.

      Once upon a time this may have been true, but when there's 1) people out in fishing trawlers/recreational vessels 2) people up on top of mountains 3) aircraft trying to fly about the place it's not really so true. Sure, most of these people could default to navigating the old fashioned ways, but you can bet heavily that one or two of them will not have a compass/sextant/etc with them, and that every so often it *will* cost lives. I'd call that a critical dependency.

    They still are taught (certainly to military navigators), but these techniques are only useful for relatively coarse navigation. Fine to get your boat home to port, but not very useful to accurately locate a particular crab pot, trawl a particular area while avoiding no-go zones or known obstructions, hold station over an dive site, oil or gas well head etc.

    This is why:

    http://en.wikipedia.org/wiki/Global_Positioning_System

    After Korean Air Lines Flight 007, carrying 269 people, was shot down in 1983 after straying into the USSR's prohibited airspace,[10] in the vicinity of Sakhalin and Moneron Islands, President Ronald Reagan issued a directive making GPS freely available for civilian use, once it was sufficiently developed, as a common good.[11] The first satellite was launched in 1989, and the 24th satellite was launched in 1994.

    Initially, the highest quality signal was reserved for military use, and the signal available for civilian use was intentionally degraded ("Selective Availability", SA). This changed with President Bill Clinton ordering Selective Availability to be turned off at midnight May 1, 2000, improving the precision of civilian GPS from 100 meters (about 300 feet) to 20 meters (about 65 feet). The executive order signed in 1996 to turn off Selective Availability in 2000 was proposed by the US Secretary of Defense, William Perry, because of the widespread growth of differential GPS services to improve civilian accuracy and eliminate the US military advantage. Moreover, the US military was actively developing technologies to deny GPS service to potential adversaries on a regional basis.[12]

    GPS is owned and operated by the United States Government as a national resource. Department of Defense (USDOD) is the steward of GPS. Interagency GPS Executive Board (IGEB) oversaw GPS policy matters from 1996 to 2004. After that the National Space-Based Positioning, Navigation and Timing Executive Committee was established by presidential directive in 2004 to advise and coordinate federal departments and agencies on matters concerning the GPS and related systems. The executive committee is chaired jointly by the deputy secretaries of defense and transportation. Its membership includes equivalent-level officials from the departments of state, commerce, and homeland security, the joint chiefs of staff, and NASA. Components of the executive office of the president participate as observers to the executive committee, and the FCC chairman participates as a liaison.

    USDOD is required by law to "maintain a Standard Positioning Service (as defined in the federal radio navigation plan and the standard positioning service signal specification) that will be available on a continuous, worldwide basis," and "develop measures to prevent hostile use of GPS and its augmentations without unduly disrupting or degrading civilian uses."

    It just LOOKS big on the map due to two-dimensional maps stretching out the northern and southern extremities of Earth.

    Scotland is only 200 miles x 150 miles in size. A fourty-mile exclusion zone (20 miles radius) would kill the entire marine economy for the western coast of the country.
