| N. Korea Jammed U.S. Reconnaissance Plane GPS |
| 2011-09-09 |
| A U.S. military reconnaissance aircraft made an emergency landing during annual South Korea-U.S. military exercises in March when North Korea jammed its GPS device, it emerged Thursday. 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. |

| #12 Airplanes can fly just fine without it. Peacetime safety measure so they don't stray over the DMZ. Won't apply when the shooting starts. |

| #10 killed everything but GPS. Not quite - but VFR might be tricky in Norkland - no interstates to follow. |

| #9 Good thing we still have alternative aviation navigation methods in America...oh wait we don't...Obama killed everything but GPS. |

| #8 Maybe they were unsure whether or not they had faulty equipment? |

| #6 The RC-7B is a military version of the De Havilland Canada Dash 7. It is like a twin otter but has 4 engines. Saw some with Greenland Air last summer in Nuuk, Greenland. |

| #5 Inertial guidance is still a good backup. |

| #4 I have a feeling that the Norks used some Chinese provided ECM, far beyond GPS jamming. But there is a whole laundry list of what that might be. |

| #3 They must have jammed more than just the GPS signal. Airplanes can fly just fine without it. |

| #2 I bet those jamming signals make a dandy homing beacon for an appropriate munition. |

| #1 Some one should tell the operators HARM don't use GPS. |
