North Korea Jammed a U.S. Spy Plane’s GPS
Well now, it looks like North Korea has found a new way of provoking the U.S. and its South Korean allies — GPS jamming. A U.S. Army RC-7B Crazy Hawk reconnaissance plane was forced to make an emergency landing last March after the North jammed its GPS receiver.
From South Korea’s Chosun Ilbo newspaper:
According
to a report the Defense Ministry submitted to Democratic Party lawmaker
Ahn Kyu-baek of the National Assembly’s Defense Committee, the RC-7B
took off from its base at 8:30 p.m. on March 4 but had to make an
emergency landing about 45 minutes later due to disruption of its GPS
functions by jamming signals transmitted from Haeju and Kaesong in North Korea at intervals of five to 10 minutes that afternoon.
The jamming signals also disrupted
the GPS devices of coastal patrol boats and speed boats of the South
Korean Navy. Several civilian aircraft in the Gimpo area were also
affected.
The North deploys vehicle-mounted
jammers that can disrupt signals within 50–100 km and is reportedly
developing a jamming device capable of disrupting signals more than 100
km away.
Based on the Dash-7 turboprop airliner, the little-known RC-7B (shown above) can almost be thought of as a low-flying JSTARS.
It’s got a ground scanning radar that allows operators to look for
moving targets like enemy tanks and also features
electro-optical/infrared cameras. It can also be fitted with gear to
intercept enemy communications.

الموضوع بإختصار
إن كوريا الشماليه إستطاعت تطوير أنظمه
للتشويش على أجهزة تحديد المواقع gps
وتستخدم هذه الأجهزه بكثره على الحدود المشتركه بينها وبين جارتها كوريا الجنوبيه
وأدى هذا التشويش لهبوط إضطررى لطائره حرب إليكترونيه أمريكيه من طراز =_self]RC-7B
تعمل لدى الجيش الأمريكى فى كوريا الجنوبيه
الطائره أقلعت فى الثامنه ونصف مساء يوم 4 مارس
وبعض فتره قليله أدى التشويش القادم من كوريا الشماليه إلى حدوث إضطراب
فى أجهزة gps الخاصه بتحديد المواقع فى الطائره مما أدى إلى هبوطها إضطرريآ
ومن ناحيه أخرى فأن البحريه الكوريه أعلنت أيضآ إن هذا التشويش
قد طال أجهزة gps الخاصه بلنشات البحريه
ويذكر أن كوريا الشماليه تستخدم أنظمه تشويش يصل مداها إلى بين 50كم إلى 100كم
وتقوم بتطوير أنظمه أخرى بمدى أكثر من 100كم
