Mysterious source jams satellite communications (Eutelsat)
NewScientist.com news service ^ | 1/26/2007 | David Shiga and AFP

Posted on 01/26/2007 9:42:33 AM PST by Rio

Paris-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.

Lots of satellite news lately. I wonder how much of it is related.

The French will apologize to the Chinese for having a satellite in their way.

Hah! That could be a very long list of suspects.

After agreeing to terms of surrender.

Maybe something else. I worked for a telcom outfit that used a lot of satellite BW for its business.

We called some interfencr the "OJ effect" Where SNG (news trucks) would rush to a breaking story and light up the transmitter and sweep it across the sky until they hit the 'right' bird.

Another issue, unless these folks are the only users, another transponder user could (on crosspol) up their power and cause the other users to disappear to ground stations.

While satcom has been around for a long time, it does have it quirks....the funniest (to me) is the twice annual outages at equinox and how the cable companies try to explain away the outages to their customer base.

I have a theory...The Chinese were knocked out too, just not mentioning it.

We did it as a cold-war style response to thier anti-sat missile stunt last week. we took out Europe as well to eleimnate any doubt to the Chinese about the source.

Bullseye... The ChiComms are testing more of their new satellite weaponry and they know the French are too weak and pacifist to do anything about an attack on one their sats, so they attacked a French satellite.

The French should bring their satellites home! How many more satellites will die because of their involvement in space?!

The 'yutes' are still not happy with the free housing being built for them, they want free internet access and cable television installed also. ;)

Why would you test it on a French satellite? You'd test it on one of your own, in order to keep it a secret.

More likely, the French just have a bad satellite design which is suseptible to interference.

Not so funny for the satcom operators. Next time a big story breaks, see if your cable/internet or other service is blasted.

BTW, most of Alaska uses satcom, too big for ground FO cable.

This was caused by Nancy Pelosi when she was seen before the nation blinking her eyes during Bush's speech the other night.

It is well known in "Moonbat circles" that blinking your eyes in that manner sends out very high radio waves that will carry the blinkers thoughts to the target.

You see she was trying to get Bush to say what she was thinking and not what his intended speech was.

But due to bush's high WI-Q, she instead jammed the sat. treported in this article, of cousre the MSM will never reveal this secret weapn of the "Moonbat Bragade"as the y are referred to.

Yes, but they are the French... ungrateful, trash-talking, and selfish so-and-so's.

I think the real answer is simply this: space is crowded, up at GEO. For any given transmit frequency, each is supposed to stay at least one degree away from its neighbor to prevent one signal interfering with the next.

Probably one of two things happened. First, perhaps somebody didn't do, or made a mistake doing, their East-West station-keeping burn, and drifted into Eutelsat's slot.

Either that, or somebody's beam pointing was off by a degree for some reason.

That stuff happens ... prolly what happened here.

Highly doubtful. There's a much easier explanation.

"There's a much easier explanation."

could be something like this:

Space Weather News for Jan. 26, 2007
http://spaceweather.com

SOLAR ACTIVITY: Something on the far side of the sun exploded
yesterday, hurling a bright coronal mass ejection over the sun's eastern limb.
An active sunspot must be lurking just around the corner. It should
appear in a few days when solar rotation carries that part of the sun into
view. Stay tuned for solar activity.

I was being sarcastic. But it wouldn't surprise me to learn that it was a ChiComm test.

Could also be Russian. The Russians have the best satellite jammers in the world. (even better than US and Chinese models)

Occam's razor is against human nature. People like to believe the more interesting stories, in this case that America is out to get them.

France is the most narcissistic nation possibly in the history of mankind. Ironically they are near the bottom of the list of nations that have something to feel vain about.

Narcissism has multiple symptoms, one is extreme envy of anything that is a challenge to their self-image of greatness, another is the feeling that others envy them. They deeply envy America, which matures into resentment then hate, and falsely think we give a damn about them. A big payoff in believing America is the source of their problems is nothing is ever their fault. "It's America's fault and we are justified in sabotaging them every chance we get."
