Astra 2E is one of the Astra communications satellites owned and operated by SES, launched to the Astra 28.5°E orbital slot on September 30, 2013[2] after a 10-week delay caused by rocket launcher problems. The satellite provides free-to-air and encrypted direct-to-home (DTH) digital TV and satellite broadband services for Europe and the Middle East.

After launch, Astra 2E underwent in-orbit testing at 43.5°E[3] and began commercial operations at 28.2°E in February 2014.[4] At that time, channels broadcast via Astra 1N (temporarily located at 28.2°E pending Astra 1E's launch) were transferred to Astra 2E and Astra 1N relocated to its design position at 19.2°E.[5]

Astra 2E is the second of three 'second generation' satellites for the 28.2°E position to replace the first generation Astra 2A, Astra 2B, Astra 2C and Astra 2D craft originally positioned there between 1998 and 2001.[6] The first, Astra 2F, was launched in 2012[7] and the third, Astra 2G, was launched in 2014 (launched on December 27, 2014[8]).

Unlike other SES/Astra spacecraft, the launch order of Astra 2E and Astra 2F is not reflected in their alphabetical names, with Astra 2F launched 10 months before Astra 2E.

Market

The Astra 28.2°E position was established in 1998 to provide digital TV, digital radio and multimedia services to the UK and Republic of Ireland, and Astra 2E’s primary mission is to continue this provision as replacement and follow-on capacity to the Astra 2A, Astra 2D and Astra 1N satellites. Along with Astra 2F it delivers programming to almost 13 million satellite homes, over 3 million cable homes, and 700,000 IPTV homes in the UK and Ireland, in particular for channels from the major UK digital satellite TV platforms, BSkyB and Freesat.[9]

ASTRA 2E also delivers broadcast and VSAT services in Europe, Middle East and Africa in Ku-band.[10] and Ka-band capacity will provide internet via satellite with download speeds of up to 20 Mbit/s to Germany.[11]

Broadcasting footprint

Astra 2E has three Ku-band downlink beams covering Europe and the Middle East:

  • The Europe beam is centred on the English Channel with maximum signal over the UK, Ireland, France, Benelux, and parts of Germany, Austria, and Spain (including a "lobe" specifically designed to serve the Canary Islands), and reception on a larger dish extending to Italy, Poland, North Africa, and the Balkans.
  • The UK Spot beam provides maximum signal (for 45 cm dishes) over the UK, Ireland, Benelux and Northern France with a sharp roll-off of signal level outside this region, in close approximation of the UK Beam of Astra 2D. This enables channels to be broadcast free-to-air but with reception effectively constrained to the British Isles, and has been the basis for the Freesat free-to-air UK platform.[12]
  • The Middle East beam is centred on the Arabian peninsula and extends to Turkey and into eastern Africa, to provide for reception with 50 cm dishes.

The Ka-band footprint for satellite broadband provides full service coverage centred on central Europe and extending to France, Italy, the Balkans, the UK, and southern Sweden and Norway.[10]

The craft is fitted with 60 Ku-band transponders.[13]

Launch delay

The launch of Astra 2E was intended to be by ILS Proton-M rocket on July 21, 2013,[14] but the previous launch of this rocket on July 2, 2013 carrying three Russian GLONASS navigation satellites ended with the rocket exploding shortly after lift off[15] and the Proton launch programme was postponed. The fault with the failed rocket was found to be the incorrect installation of three angular rate sensors, the Russian Federal Space Agency (Roscosmos) reported,[16] and the launch programme was recommenced in September 2013.

TV Channels on Astra 2E

Below is a list, as of July 2015, of the TV and radio channels broadcast from Astra 2E on its UK Beam and European Beam (the UK Beam is the most difficult to receive outside the British Isles):[17]

In the list, TV channels broadcast with a one-hour delay are shown Channel +1hr. Where both the original and the delayed channel are broadcast from the same transponder, this is shown in one entry as Channel [also +1hr].
