BBC: Iran targets new satellite to jam broadcast

BBC: Iran targets new satellite to jam broadcast

Posted: Sep 08, 2011 1:41 AM Updated: Sep 08, 2011 1:42 AM
LONDON (AP) - The BBC says Iran has stepped up the jamming of its Farsi-language television service by interfering with the operation of a Eutelsat satellite.

Jamming from within Iran has affected BBC Persian television since its launch in 2009, and the British broadcaster says that one of Eutelsat's high-power Hotbird satellites has been targeted since July.

But the BBC now says that Iran has expanded its jamming to target the Paris-based company's W3A satellite, which covers Africa, Europe and parts of the Middle East.

BBC foreign editor Jon Williams said in a message posted to Twitter that "we call on Tehran authorities to stop these illegal acts."

Eutelsat did not immediately return a call seeking comment Wednesday. BBC Persian is still broadcasting on other satellites.

BBC Persian TV now jammed on two satellites

BBC Persian TV now jammed on two satellites

The deliberate jamming of BBC Persian TV from within Iran has now moved to two different satellites for the first time. The Hotbird satellite has been targeted since July and now the Eutelsat W3A satellite is subject to interference.

Eutelsat, the satellite owner, has validated the geolocalisation of the source of the interference as being in Iran.

Both BBC and Eutelsat condemn this extensive and deliberate act that is contrary to international conventions for the use of satellites.

Peter Horrocks, Director BBC Global News, said: "We continue to work closely with Eutelsat and the international regulatory community to find means of countering this interference. It is well known that Iran are actively engaged in the International Telecommunications Union (ITU)'s Radio Regulations Board yet their fellow countrymen continue to flout the very conventions by which the industry operates.

"We call on those of influence to do all they can to impress upon Iran the illegal nature of the jamming and the need to cease this activity immediately."

Last year, the ITU Radio Regulations Board urged Iran to end interference hampering Eutelsat satellite operations.

BBC Persian TV continues to stream live online and on satellites T12 (15 degrees West) and EB2 (25.5 degrees East).

BBC Persian television launched in 2009 and has suffered similar deliberate attempts to interfere with its signal intermittently ever since.

Broadcasting of Al Arabiya resumes after deliberate jamming from unknown source

Broadcasting of Al Arabiya resumes after deliberate jamming from unknown source

Al Arabiya News Channel was jammed by unknown sources beginning early on Wednesday. It returned to normal broadcasting later on Wednesday.

This deliberate jamming seems to have been intended to interrupt Al Arabiya’s coverage of events taking place in the Arab region, especially in Libya and Syria.

The channel can be watched on its original permanent frequency on the Nilesat (12341 Vertical), in addition to the alternative frequencies of (12476) and (11488.)

Viewers can either do an auto-search for the new frequency or through the manual search.

This is not the first time that Al Arabiya has been deliberately jammed. At the beginning of the Libyan revolution the broadcast was jammed, and an investigation concluded that the jamming was instigated from a Qaddafi-regime intelligence center east of Tripoli.
