How does Starlink work?

Plug in the dish - or terminal as it's officially called - and it will automatically connect itself to the nearest Starlink satellite in the sky, of which there are more than 2,000.

The satellite then communicates with the nearest ground station, or gateway, which supplies the internet.

These gateways are located around the world, but they can't be too far away from the place getting an internet connection. Fortunately for Ukraine, there is a gateway in neighbouring Poland.

The internet connection travels from the gateway to the satellite, and then to the terminal. Users simply plug their router into their terminal and the tech takes care of the rest.

One of the major issues with previous iterations of satellite internet is the delay, but Starlink's constellation of satellites is a relatively new technology - they operate in low-Earth orbit, so the delay is measured in milliseconds rather than seconds.

Usually this would come at a cost. In the UK, it will cost you £495 for the dish (including shipping), and then a subscription of £89 per month. There is no indication that Ukrainians will be charged for the service.

The terminals need a clear view of the sky in order to work, and there is an app to help users find a suitable spot to place them.

Ordinary considerations are overhanging trees and other obstructions - in Ukraine, users will have to consider safety and how they may appear to Russian forces.

Once set up, the speed they offer varies but one user who already had access to a terminal tweeted on Monday that he had reached speeds in excess of 200 Mbps (megabits per second) for a while.
