How to Jam a Worldwide Satellite TV Broadcast

An anonymous reader submits: "According to an MSNBC article, 'it's simply a matter of aiming a strong signal at the uplink transponder on the satellite and overwhelming the...broadcaster's signals...You need a dish, some power, not too much. You put up a test pattern ... and do a sweep and find the transponder on the satellite you want to jam. It could even be smaller than the standard 6-meter dish. It could be a small dish with a lot of power.' This was apparently how an Iranian satellite television station was knocked off of Loral Skynet's TelStar-12 a few days ago. Loral contacted TLS, a company which specializes in satellite broadcast security, who quickly located the source of the jamming to Cuba."

    it's simply a matter of aiming a strong signal at the uplink transponder on the satellite

    Worse, send a really powerful signal (read- military radar magnetron hooked up to mondo dish) and you can permanently fry that transponder, and do so with a burst so brief and directed that it's not terribly easy for anyone to figure out whonunnit. It's a great piece of asymetric information warfare - spend a couple of million dollars to knock out a few dozen civilian comsats, each tens or hundreds of millions of dollars worth. Best of all, it's quite possibly not in breach of any international treaty !

    Excuse me, I have to go now, my mechanical pirnahas are hungry...

  2. Phil-14's reactionary bull puckey - History lesson by securitas · · Score: 5, Insightful


    The fact that you decided to resort to a personal attack and innuendoes says far more about you than anything else you had to say. Instead of behaving like a reactionary, McCarthyist zealot and making claims about all sorts of conclusions that I supposedly reached, try reading a little closer.

    I said it seems more likely that a signal would have come from Guantanamo. Considering the massive signals operation there, that's perfectly reasonable.

    Someone else mentioned in the thread that it's possible that it was an accidental jam if it was the USA because mistakes like that have been known to happen. A more cynical view would be that it was intentionally done to manufacture an incident like the Gulf of Tonkin hoax that was eventually used to justify the Johnson administration's massive expansion of the war in Vietnam. The final possibility that is mentioned in the article is the Russian-built Cuban station. It seems strange that the Russians would have two stations that were only seven miles apart (before the closure of Lourdes), but that is also entirely possible.

    The fact is that neither you nor I have any concrete proof of who was responsible for the jamming. Everything else is speculation.

    The CNN Los Angeles bureau reported in June that the backers of the U.S.-based Iranian dissident satellite television stations are Shah-ists, showing the portraits of the Shah plastered all over the studios. We now know that a 1953 coup orchestrated by the CIA, helped overthrow the short-lived, democratically elected Mossadegh government and snuffed out budding democracy in Iran. The U.S. then installed the Shah and trained his notoriously brutal SAVAK internal security forces. The Shah went on to become one of the most savage dictators of the 20th century until the Iranian revolution in 1979.

    To get back in bed with the Shah's supporters today is directly counter to the stated goal of fostering a democratic, free society in Iran which might have thrived if not for the U.S.-backed coup 50 years ago.

    To Phil-14: The last time I checked I have the right to free speech. It seems you would prefer that we live in a Stalinist, Communist regime that would put an end to anyone who didn't agree with your narrow point of view.

    The MSNBC report may be 100% correct. An open mind will at least acknowledge that there are other possibilities.
