Advertisement Elon Musk's SpaceX started providing Ukraine free access to its Starlink internet service shortly after Russia's full-scale invasion in 2022. The strategic benefits were clear: Skylink would provide internet access to the Ukrainian people and military after Russia had disrupted internet connections. The technology has been instrumental in guiding Ukraine’s drone strikes on Russian tanks and positions. But according to Ukraine's intelligence services, Russian soldiers have been using the technology for months in the territories they occupy. That would mean Russia was circumventing sanctions by importing products via third parties. Starlink's operator and the Russian government have both denied the allegations. SpaceX, which owns Starlink, says it is not engaged in business with the Russian government or the country's military. The company said in a statement that if it discovered Starlink terminals were being deployed by unauthorized parties, it would investigate and potentially disable the terminal. The Kremlin said that Starlink terminals were neither certified for use in Russia, nor had they been officially delivered to the country, and that it was therefore impossible for them to be in use. Since 2019, space company SpaceX has launched around 3,000 satellites into low Earth orbit Image: Science Photo Library/imago images How does Starlink work? The Starlink program supplies internet to regions with sparse telecommunications infrastructure, like at sea, in remote rural areas, or in regions where government restrict internet access. Starlink provides Internet access by transporting data via light, similar to a fiber optic cable. This transfer is facilitated through a network of small satellites that communicate with designated ground receivers. SpaceX has around 3,000 satellites in low Earth orbit, a section of space below an altitude of 2,000 kilometers (1,200 miles) from the Earth’s surface. The satellites share an orbit with the Hubble space telescope and the International Space Station. SpaceX began launching Starlink satellites in 2019. The company said it plans to expand the network to up to 12,000 satellites, with a possible extension to 42,000. Like other satellite internet services, several components are needed on the ground and in the sky to provide internet access through Starlink. First, in order to connect devices like cellphones and computers to nearby satellites, a receiver device is needed on the ground. That device independently connects the receiving dish, which resembles a TV satellite dish, with an available satellite and the internet connection is established. Is Starlink worth it for private users? Starlink is not the first service to offer satellite-supported internet, but it does have some advantages over its competitors. Starlink satellites orbit the Earth at an altitude of 328 to 614 kilometers, significantly lower than their competition. HughesNet, one of Starlink's main competitors, orbits the earth at an altitude of 35,000 kilometers. Its low orbit allows Starlink's data to travel ten times quicker than that of HughesNet. Will Elon Musk eventually sell the private Starlink project to the highest bidder? Image: JIM WATSON/AFP So far, Starlink is only available in 40 countries, which include parts of the US and Canada, central and southern Europe, parts of Latin America, and southern Australia. In other words, many areas for which Starlink was originally intended still do not have complete coverage. This could be partly due to the fact that Starlink's satellite internet is very expensive. The receiver alone costs $600 (€620) while monthly usage fee is another $110. Satellite internet is hardly worthwhile in regions with good or satisfactory network coverage, unless someone frequently travels by boat or motor home and wants a powerful, permanent internet connection in remote regions. Why is the Starlink program so controversial? Fast internet for everyone everywhere sounds promising at first. But Starlink satellite internet is controversial. The provision of Starlink to Ukraine took place as a public agreement between Musk and Mykhailo Fedorov, Ukraine's Deputy Prime Minister and Minister of Digital Transformation, via the online message platform X (formerly Twitter) — in other words, without any public debate or government oversight. There are also concerns over what would happen if Musk sold the private Starlink project to the highest bidder after completion. What would happen if totalitarian states or private companies with even less government oversight than SpaceX gain control over this network? Starlink plays an important role for Ukraine in its war with Russia, which is entering its third year. But Ukraine and SpaceX have had their differences. One such disagreement came about when SpaceX boss Elon Musk claimed to have prevented a Ukrainian attack on a Russian fleet in the Black Sea by refusing to activate Starlink terminals around the Crimean peninsula.
