SES Astra – The Company Behind Europe’s TV Satellites

When people talk about “the Astra satellites” or “the Sky satellites”, they are usually referring to the group of communications satellites operated by SES and branded as Astra. These satellites carry television, radio and data services across Europe, including many of the UK’s most popular TV channels.

What is SES Astra?

SES is one of the world’s largest satellite operators. The company is based in Betzdorf, Luxembourg, and operates dozens of communications satellites around the world.

The Astra name refers to SES’s European satellite system. The first Astra satellite, Astra 1A, launched in 1988 and helped revolutionise satellite television across Europe by making direct-to-home satellite TV practical using smaller dishes.

For many years, the satellites were operated under the subsidiary name “SES Astra”, although today they are simply part of SES itself. The Astra brand is still widely used because it is so well known in broadcasting and satellite TV.

Who Owns SES Astra?

SES is a publicly traded Luxembourg-based satellite operator. It is not owned by Sky, the BBC, Freesat or any TV broadcaster.

Instead, SES owns and operates the satellites, then rents capacity on those satellites to broadcasters and TV platforms across Europe and beyond.

Customers include:

  • Sky UK
  • Freesat
  • BBC
  • ITV
  • Channel 4
  • European broadcasters
  • Radio stations
  • Internet and data providers
  • Government and commercial communications companies

This is similar to how broadcasters rent space on mobile phone masts or internet infrastructure rather than owning the physical network themselves.

The Astra Satellites Used for UK TV

UK satellite television is mainly broadcast from the Astra satellite group located at the 28.2° East orbital position.

This orbital position is home to several Astra satellites that beam signals towards the UK and Ireland. These satellites carry:

  • Sky UK channels
  • Freesat channels
  • BBC channels
  • ITV channels
  • Channel 4 and Channel 5 services
  • Hundreds of TV and radio channels

The Astra 28.2° East position became the main home of UK satellite broadcasting during the 1990s and remains the core satellite TV location for Britain and Ireland today.

The History of Astra Satellites for UK Television

The UK television services at 28.2° East have been carried by several generations of Astra satellites over the years.

As older satellites reached the end of their operational life, SES replaced them with newer spacecraft offering improved coverage, reliability and broadcasting capacity.

Astra 2A

Astra 2A launched in 1998 and became one of the first major satellites used for the expansion of Sky Digital in the UK and Ireland.

It carried a mixture of UK and European television services and played a key role in the early growth of digital satellite TV.

Astra 2B

Astra 2B launched in 2000 and added further broadcasting capacity at 28.2° East as demand for digital television channels rapidly increased.

Astra 2C

Astra 2C launched in 2001. Although not originally dedicated solely to UK broadcasting, it was used at different orbital positions during its lifetime and occasionally supported services around the Astra 28.2° East position.

Astra 2D

Astra 2D launched in 2000 and became especially important for UK television.

It introduced the tightly focused “UK Spot Beam”, allowing broadcasters such as the BBC to concentrate signals mainly over the British Isles rather than across all of Europe.

This allowed free-to-air UK channels to broadcast without requiring expensive Europe-wide encryption.

For many expats in Spain and other parts of Europe, Astra 2D became famous for its more limited reception area compared to earlier Astra satellites.

The Current Astra Satellites for UK TV

Today, UK television services are mainly carried on a newer generation of Astra satellites at 28.2° East.

Astra 2E

Astra 2E launched in 2013 and introduced a new generation UK Spot Beam for British television services.

Astra 2F

Astra 2F launched in 2012 and carries a mixture of UK and pan-European television and data services.

Astra 2G

Astra 2G launched in 2014 and completed the modern replacement programme for the older Astra 2 satellites.

Together, Astra 2E, 2F and 2G now provide the main satellite capacity for Sky, Freesat, BBC, ITV and many other television and radio broadcasters serving the UK and Europe.

The Common Misconception – “Sky Owns the Satellites”

One of the biggest misunderstandings in UK satellite TV is the belief that Sky owns the Astra satellites.

They do not.

Sky is simply one of SES’s largest customers.

Sky rents transponder capacity from SES on the Astra satellites in order to broadcast its channels to subscribers. This relationship has existed since Sky’s early analogue satellite days in the late 1980s.

In fact, SES regularly announces contract renewals with Sky for satellite capacity, proving that Sky is effectively leasing space on the satellites rather than owning them.

This is why:

  • BBC channels use the same Astra satellites
  • Freesat uses the same satellites
  • Thousands of non-Sky channels are also carried there
  • Dish alignment for Sky and Freesat is identical

Sky controls its subscription platform, receivers and encryption systems — but not the satellites themselves.

Why Astra Satellites Are Important

The Astra satellite system transformed television in Europe by allowing reliable direct-to-home broadcasting over huge areas using relatively small satellite dishes.

Even today, satellite broadcasting remains extremely efficient for delivering:

  • Live sport
  • News channels
  • UHD / 4K broadcasts
  • National TV coverage
  • Rural television reception
  • Backup distribution for broadcasters

Satellite delivery also allows broadcasters to reach millions of homes simultaneously without depending on local internet speeds.

Are Astra Satellites Still Important Today?

Despite the growth of streaming services, Astra satellites remain a major part of UK television infrastructure.

Sky continues to renew long-term agreements with SES for satellite capacity, and millions of homes across the UK and Europe still receive television via Astra satellites every day.

While the television industry is gradually moving toward internet delivery, satellite broadcasting still offers advantages in reliability, nationwide coverage and live event distribution that are difficult to match purely through streaming.

Conclusion

SES Astra is the company and satellite system behind much of Europe’s satellite television broadcasting. Although many viewers refer to them as “Sky satellites”, the satellites themselves are owned and operated by SES, with Sky simply renting capacity alongside broadcasters such as the BBC, ITV and Freesat.

The Astra satellites at 28.2° East remain one of the most important television broadcasting positions in Europe and continue to power satellite TV services for millions of homes across the UK and Ireland.
