Mysterious source jams satellite communications
 Hat Tip: New Scientist Space via World News DailyParis-based satellite company Eutelsat is investigating "unidentified interference" with its satellite broadcast services that temporarily knocked out several television and radio stations. The company declined to say whether it thought the interference was accidental or deliberate. The problem began Tuesday afternoon, blocking several European, Middle East and northeast African radio and television stations, as well as Agence France-Presse's news service. All transferred their satellite transmissions to another frequency to resume operations. Theresa Hitchens of the Center for Defense Information think-tank in Washington DC, US, says there have been cases of deliberate satellite jamming in the past, but it is hard to see what motivation there would be in this instance. "It's really puzzling to me," she told New Scientist. "If it was accidental, why would they be so secretive about saying what the source was and if it's deliberate, you've got to wonder why it just seems to me to be an odd target, unless someone's ticked off at the French," she says. Hitchens points out that there have been cases of deliberate jamming, including one in the 1990s when Indonesia and Tonga had a dispute over which country had the rights to a particular satellite orbital slot. Tonga had leased the slot to a satellite firm based in Hong Kong, but Indonesia had its own satellite in the same slot and proceeded to jam the Hong Kong satellite. In a more recent incident, the US claimed in 2003 that Cuba was jamming its satellite broadcasts into Iran. Posted by: FOTSGreg 2007-01-27 |
