The Iranian remote sensing satellite, named Khayyam, is due to be launched from the Baikonur Cosmodrome in Kazakhstan on Tuesday, Russia's State Space Corporation said earlier this week.

"All orders related to the control and operation of this satellite will be carried out and issued from day one and immediately after launch by Iranian experts based in Iran's... space bases," the Iranian Space Agency said in a statement.

The Washington Post on Thursday reported that Russia "plans to use the satellite for several months or longer" to assist its war efforts in Ukraine before allowing Iran to take control of it, according to anonymous Western intelligence officials.

They added that the satellite will provide Tehran with "unprecedented capabilities, including near-continuous monitoring of sensitive facilities in Israel" and in the Gulf.

But Moscow would first use the satellite to "enhance its surveillance of military targets" in the Ukraine conflict, the report said.

The Iranian space agency dismissed the claims as "untrue", adding that "no third country is able to access the information" sent by the satellite due to its "encrypted algorithm".

The satellite, apparently named after 11th-12th century Persian polymath Omar Khayyam, aims to "monitor the country's borders", enhance agricultural productivity and monitor water resources and natural disasters, the Iranian agency said earlier this week.

The announcement regarding the new satellite was made two weeks after Russian President Vladimir Putin visited Tehran.

In June 2021, Putin denied a US media report that Russia is set to deliver an advanced satellite system to Iran that will vastly improve its spying capabilities.

Iran insists its space programme is for civilian and defence purposes only, and does not breach the 2015 nuclear deal between Iran and world powers, or any other international agreement.

Western governments worry that satellite launch systems incorporate technologies interchangeable with those used in ballistic missiles capable of delivering a nuclear warhead, something Iran has always denied wanting to build.

Iran successfully put its first military satellite into orbit in April 2020, drawing a sharp rebuke from the United States.

In March, the Revolutionary Guards, the ideological arm of Iran's armed forces, announced it had successfully put a military "reconnaissance satellite", Nour-2, into orbit.
