North Korea Launches Missile and Tries To Jam GPS Signals (go.com)
An anonymous reader writes: Hours after North Korea fired a short-range missile into the sea in retaliation for ongoing U.S. join military drills with South Korea, they started jamming GPS navigation systems near its border with South Korea, affecting hundreds of fishing boats but not causing any immediate danger. There were no disruptions to drivers' satellite navigation system or air traffic, but warning messages were broadcast in affected areas warning ships not to rely on their GPS navigation. In a statement, the South Korean Ministry of National Defense said: "North Korea has been continuously disrupting GPS system since 7:30 pm [Thursday] and thereby interfering and hampering our military movements, which is threatening the safety of our people."
The little dog that used to just go yap yap yap is now frothing at the mouth, too. Isn't it time to euthenize it?
Are YOU using the TOOL, or is the TOOL using YOU? Think about it!
There's really no such thing as "jam proof" - merely resistant. Even directional antennas are not perfectly directional, and will still receive off-axis signals, just at some attenuated strength. Any sufficiently strong nearby source can overwhelm a much more distant and weaker source.
In a "real" war, it wouldn't be jamming that is the problem anyway. The problem would be that the GPS constellation would go bye-bye from the other guy's anti-sat weapons. Not that many countries have those, but the most sophisticated adversaries do have them.
The US actually likes to provoke NK. If NK gets riled up, it gives the US more excuses to place more troops or missile defenses in S. Korea/Japan. These missile defenses would do nothing to help S. Korea, considering that N. Korea has tons of artillery already pointed towards Seoul which is only a few miles from the border. Instead they only use is to help contain both Russia + China. More so towards containing China.
The purpose of military training exercises is not to "provoke" somebody, that is childish and silly.
Unless you're doing it in front of their house.
