SorryTomato writes "The Tamil Tigers Liberation Front a separatist group in Sri Lanka, which has been classified as a terrorist group in 32 countries has moved up from routine sea piracy to a space-based one. They have been accused of illegally using Intelsat satellites to beam radio and television broadcasts internationally. Intelsat says that they will end the transmissions 'within days.' Intelsat has been accused of having business links with Hezbollah before, but claim that they are blameless this time and LTTE was using an empty transponder."

I know, because I work for a satellite company. Communications satellites normally have no protection at all, if you know the right frequency, have a powerful enough transmitter and antenna, and know where to point your signal, you can do it. And it's *extremely* difficult to avoid, there are very few technical countermeasures. You can beam a more powerful carrier over the pirate, but this means you lose the bandwidth anyhow and, in case of an intentional interference, the pirate can just shift his frequency and start over.
It happens all the time accidentally. Sometimes amplifiers are defective, or they are inadvertently turned to the wrong frequency. These accidental interferences happen everywhere, and cost millions of dollars per year for every operator in terms of bandwidth that becomes unusable.
Since a satellite has a wide coverage area, it's very difficult to find the transmitter. There are some very expensive systems to locate interferences, they work based on small shifts in frequency and time that depend on the transmitter location, but these systems cannot locate a transmitter with an accuracy better than tens of miles. After finding the general area where the interference originates, one must sweep the whole region with a helicopter equipped with a directional antenna. Very messy and very expensive.

IIRC it was one of the Blackhat conference speakers who outlined the nasty possibility of a satellite somewhere in a geosynchronous constellation being hijacked and deliberately crashed into another one. Given that this area is fairly densely populated, the debris could start a chain reaction and do a lot of damage.

It might not have been approved by the higher ups either in the family/party. India's Minister for Communication Kalanidhi Maran, is a nephew of the Chief Minister of Tamil Nadu and their family owns the SunTV conglomerate. Tigers are to be feared, their pledge of alligiance to their leader Prabakaran supercedes any other consideration.

According to Asian Tribune, the satellite channel [asiantribune.com] was part of the ceasefire agreement between the LTTE and the government of Sri Lanka. Since Ranil Wickremasinghe [wikipedia.org] hasn't been Prime Minister of Sri Lanka since 2004, this agreement that LTTE could broadcast obviously isn't exactly new.
Speculation time:
Some people are claiming that the LTTE is paying [wordpress.com] for the broadcasts. It sounds like someone at Intelsat may have accepted a contract based on the ceasefire agreement, only to get burned now that a different political party is in charge in Sri Lanka.

The theory how armed resistance can be used to overthrow government is very old and goes along the lines of: provoke the authorities with violence until they start to react as violent, but against their own innocent civilians. Every state action should generate more supporters for your cause until you have a large enough majority to oust the regime, or they just downright give up. If you follow that theory, al-qaida was very successfull with their wtc attack. The US overreacted so violently that they lost all their goodwill in the rest of the world. Indirectly this may lead to the withdrawal of the US from Saudi soil.
Btw, personally I think all violence is wrong, but neither do I like the Myopic US views on 'terrorism'.

The LTTE are very ruthless and achieved their position partly by killing any dissenters. They are also the world leaders in suicide bombings, both in the number of attacks and the technology used. I suspect if the Sri Lankan forces had been more restrained, the LTTE's own brutality would have undermined them.
They are certainly ingenious and are unique among their peers in operating on land, sea and in the air - they recently used light aircraft to bomb an air force base, and had dropped bombs and got away before the air force get its air craft off the ground.
In the meantime, Sri Lanka faces horrible side effects from war. Corruption, vote-rigging, suppression of free speech, a rise in Buddhist fundamentalism and huge economic damage.
On a more cheerful note, its a great time to go to Sri Lanka on holiday. The hotels are dirt cheap. The conflict is localised, foreigners are not targets, and you would be safe from violence as long as you avoid the north and east of the country. The risks from Sri Lankan driving are another matter....
Posting anonymously for obvious reasons: my profile links to my blog and I do not want to make unnecessarily make enemies in Sri Lanka as I spend a lot of time there. The fact that I feel it necessary to be anonymous should tell you a lot about the state of free speech in Sri Lanka.

Terrorists that "win" get to call themselves freedom fighters because they "won". Terrorists who didn't "win" get called terrorists by the "winners".
That could cover just about any form of violence whether perpetrated by governments or terrorists/freedom fighters, east or west.

Yet, because of the fact I am Tamil, you do gooders are supposed to now be looking at everything I do? It doesn't matter the fact that I have lived in the UK for so long, I cannot even speak Tamil properly.
Its bad enough, going to Sri Lanka, and being sometimes treated like dirt by immigration, customs, and checkpoints, simply because I was born in Jaffna, fearing I would be kidnapped or killed by extra-legal gangs, operating with apparent clandestine approval from authorities.
Should I expect the same treatment from my "friends"?
Should I likewise assume that every "white man" is a potential KKK, or BNP member?
I have many friends who are Singhalese (the 'other side'), who treat me as a brother.

See "Black July" http://en.wikipedia.org/wiki/Black_July [wikipedia.org] and other awful cases of poor human rights and racist actions by a few in power.
I have seen the problem at face, as I have recently (November 2006) been to Sri Lanka myself: as a tourist, and stayed in a hotel, in Colombo, for only 3 nights, to see my girlfriend who lives in Colombo (she is half Singhalese, half Tamil, by the way) Whenever my hotel car was stopped at numerous checkpoints, and they saw on my BRITISH passport, that I was born in Jaffna, I was given "special treatment". I usually responded with a query of the officers Badge Number, as well as reasons for the delay in letting me through, which usually for me, made them back off.
But others are not so lucky.
A friend of mine, was recently spotted as a Tamil at the immigration in Colombo airport, and was kidnapped en route to the capital, and was help, until he paid a ransom of £2000. The kidnapping was done by gangs, supporting the current administration, with the help of the police, and authorities.
Unfortunately the current administration in Sri Lanka, has a unwritten, but oft repeated view that all Tamils are LTTE. Amnesty International has been recently doing a large campaign highlighting the general lack of human rights in Sri Lanka http://web.amnesty.org/library/Index/ENGASA370102
No Tamil Sri Lankan wants to separate from the rest of the country, they just desire to live together in harmony. But when the government does not protect, and then attacks members of their own people, of cause people will support the LTTE in desperation.
It's a really sad tragic situation, and destroying a very beautiful country.

You are incorrect regarding antenna size. Satellite communications is possible using COTS equipment such as a Ku-band (about 14 GHz up, 11 GHz down) antenna about 1 m across. If you want to go C-band (6 Ghz/4 GHz), then a dish about 2.5 m across is sufficient. You only need about 100-400 W of power, again available in COTS equipment.
If you're not concerned with some of the requirements for your transmitted signal (particularly beamwidth), you can use dishes even smaller than these, provided you have sufficient transmitter power.
Such equipment must be available on the black market; if groups such as the Tamil Tigers can afford to buy black-market weapons, I can easily imagine the black-market availability of such technology for the right price.

I'm certain Intelsat don't want any non-paid for signals period, though the legalities of pirate transmissions are a bit of a grey area depending on which country you are in. I have seen on many occasions a sweeping CW (carrier wave) running back and forth across what I assume are unwanted transmissions. I'd say there's not really much more Intelsat can do except suck it up and try to identify unknowns a tad faster than they have been doing in the past, and then simply try to disrupt the signal - no guarantee this will work though.
The fine article makes it sound like Intelsat have some sophisticated system that'll let them drop the transmissions with a flick of a few switches - this is an interesting feel good fluff explanation probably more aimed at their investors. What they really mean is that there is sweet FA they can do about it beyond asking nicely for the naughty men to turn off their bad signal, otherwise they'll take their transponder and switch it off for everyone, only for a few minutes though.
