Intentional GPS Jamming On the Increase

benst writes "Here's yet another way to measure the success of GPS: by the efforts to negate it. While unintentional jamming continues to rise, intentional jamming by both foreign military forces and at-home miscreants of various stripes has shown increased vigor in the past six months. Related here are recent instances of intentional jamming on each side of the border, and (briefly outlined) one initiative mounted by the National Geospatial Intelligence Agency (NGA) to counteract it. Also, here are some ways to detect and prevent jamming."

    > Just put loads of debris in the same orbit at a greatly different speed

    Unfortunately, the same orbit means the same speed - different speeds, different orbits.
    You need to create an orbit that crosses the satellite's orbit at some point and wait until your debris and the satellite meet at the crossing (since their orbiting times are different, they will, if you wait long enough).

    I think the problem is that GPS is a commercially funded operation.

    Um, no, it isn't. It's owned, lock, stock and barrel, by the US military. Civilian devices are allowed to access it, but the satellites are not commercially owned.

    If the military wanted its own "secret" GPS system, it would have to launch a boatload of satellites up there to match the current configuration.

    Or they could just ring up the CO of the US Air Force's 50th Space Wing, since that's who owns and maintains the current "boatload of satellites".

    They already do this for the bridges on Storrow Drive that runs along the Charles River in Boston (they would get jammed under the bridge). Problem was that truckers hit it so much they were regularly destroying the sign. You also need to place it in a spot where the truckers can take an exit instead of trying to reverse up a busy road.

    his type reminds of the people who think it's okay to drive 61 mph in a 65 mph zone in the FAST LANE.

    Yeah, sure they are technically correct but intentionally and more than a bit arrogantly lack any pragmatic approach to driving on the road.

    In Wisconsin at least, left lane squatters are not "technically correct". The statute requires vehicles traveling "at less than the normal speed of traffic at the time and place and under the conditions" to be driven in the right-hand lane. It doesn't matter what the speed limit is. Since this behavior tends to provoke unsafe driving by others if not outright road rage, I think citing more people for it would definitely make the roads safer.
