Avanti’s network consists of three high throughput satellites in orbit, called HYLAS-1, HYLAS-2; a multiband satellite called Artemis and HYLAS-4 satellite, launched by Arianespace on April 5th, 2018. A fourth satellite, HYLAS-3 is under construction. Avanti also operates an international fibre network connecting data centres in several countries. HYLAS stands for Highly Adaptable Satellite, a product of third millennium state of the art European Space technology (ESA).

Inmarsat provides the satellite control centre infrastructure and services in London and Italy (Fucino).


Avanti was founded by astrophysicist David Bestwick in 1996 to advise other firms on how best to use satellite technology.

When David Williams (now CEO) bought into the company in 2002 it was worth £9,000. His wife lent them £10,000 and they started the company in his spare room. Today it has a market value of £340million and has raised some half a billion pounds of funding.

The HYLAS-1 satellite system has been developed through a Public Private Partnership between ESA and Avanti and was launched in November 2010.  It was the first superfast Ka-band in Europe. The Ka-band earth stations for HYLAS-1 are located at Goonhilly and Lands End, Cornwall, UK.

HYLAS-2, was launched in August 2012 and extends Avanti's coverage to Africa, the Caucasus and the Middle East.

Avanti also owns a multiband satellite called ARTEMIS, with a fourth and a fifth satellite under construction called HYLAS-3 and HYLAS-4. HYLAS-4 was launched by Arianespace launch operator on April 5th, 2018.

In 2012 Avanti announced a conditional placing of 26,785,714 Ordinary Shares with new and existing institutional investors to raise approximately £73.8 million to fully fund the cost of the design, construction and launch of HYLAS-3. HYLAS-3 will be a “hosted payload.  HYLAS-3 would provide Ka band services, as with HYLAS-1 and HYLAS-2.
