Best Korea trolling the south

[Locutus]

"North Korea has been looking for new and inventive ways to mess with South Korea. It seems that their missile launch fizzled a bit though, so those wacky folks from the North have bought a few GPS jamming trucks from Russia and are now blocking GPS signals around their city of Kaeson. While Kaeson is around 60 Km inside their borders, the jamming circle is around 100 Km, so it actually covers good parts of South Korea including the airports at Inchon and Gimpo. While no accidents have been caused as yet, it has caused quite some disruption and has made ocean going craft suffer as well due to their heavy reliance on GPS signals."

The weapon is designed to detonate high above the Earth's atmosphere, releasing huge amounts of energy, some of which is in the form of gamma rays. It is highly effective in destroying electronic devices such as computers, televisions and cars within a radius of 100 kilometers, according to experts.

Within a radius of 100K translates to an altitude of 100K - and this thing's supposed to detonate "high above the Earth's atmosphere"

(from Wiki) The Kármán line, located within the thermosphere at an altitude of 100 km, is commonly used to define the boundary between the Earth's atmosphere and outer space. However, the exosphere can extend from 500 up to 10,000 km above the surface, where it interacts with the planet's magnetosphere.

Sounds like Star Trek threats to me....
