North Korea appears to be protesting the joint U.S. and South Korean military maneuvers by jamming Global Positioning Devices in the south, which is a nuisance for cell phone and computers users -- but is a hint of the looming menace for the military.It is also an act of war.
Since March 4, Pyongyang has been trying to disrupt GPS receivers critical to South Korean military communications apparently in protest of the ongoing joint military training exercises between South Korean and U.S. forces. Strong jamming signals were sent intermittently every five to 10 minutes.An EMP device is of great concern, of course, but the norks have trumpeted great success with boogie-man weapons before, despite their having fizzled horribly...
The jamming, however, has raised questions about whether the Korean peninsula is bracing for new electronic warfare.
The North is believed to be nearing completion of an electromagnetic pulse bomb that, if exploded 25 miles above ground would cause irreversible damage to electrical and electronic devices such as mobile phones, computers, radio and radar, experts say.
The current attempts to interfere with GPS transmissions are coming from atop a modified truck-mounted Russian device. Pyongyang reportedly imported the GPS jamming system from Russia in early 2000 and has since developed two kinds of a modified version. It has also in recent years handed out sales catalogs of them to nations in the Middle East, according to South Korea's Chosun Ilbo.Civilian aircraft... International law, and, again, act of war.
This is the second time North Korea has sought to interfere with military communications. Pyongyang is thought to have been behind a failure of GPS receivers on some naval and civilian aircraft during another joint military exercise in August.
