Astra 2Gis one of theAstracommunications satellitesowned and operated bySES,launched to theAstra 28.2°Eorbital position on 27 December 2014, at 21:37:49UTCfromBaikonur Cosmodrome.[2]

Astra 2G is positioned at 28.5° East (part of the Astra 28.2°E orbital position) and is the last of three "second generation" satellites launched to this position to replace the first generationAstra 2A,Astra 2B,Astra 2CandAstra 2Dsatellites originally positioned there between 1998 and 2001, and it joinedAstra 2EandAstra 2Flaunched in 2013 and 2012, respectively.[3]

Market[edit]

Astra 2G carries bothKu-bandandKa-bandpayloads and will deliver broadcast, VSAT and broadband services to Europe, theMiddle EastandAfrica,and will also provide the ability to connectWest Africato Europe via Ka-band.[4]The Astra 28.2° East position was established in 1998 to providedigital television,digital radioand multimedia services to the United Kingdom and Ireland, and a major part of Astra 2G's mission is to continue, extend and backup this provision. Along with Astra 2E and Astra 2F it will deliver programming to almost 13 million satellite homes, over 3 million cable homes, and 700,000Internet Protocol television(IPTV_ homes in the United Kingdom and Ireland, in particular for channels from the major United Kingdom digital satellite television platforms,BSkyBandFreesat.

Astra 2G also supportsSATMED,a satellite-based e-health platform developed by SES and supported by theLuxembourgGovernment and the Ministry for Cooperation and Humanitarian Action which enables communication between doctors, enabling the transfer and exchange of medical knowledge and supporting tools for medical e-learning and e-teaching to improve public health in emerging and developing countries, particularly in isolated areas.[2]

Broadcasting footprints[edit]

Astra 2G has three Ku-banddownlinkbeams and one Ka-band beam:[4]

  • The European beam is centred on theBeneluxcountries with reception from a 60 cm (24 in) dish available across most of Europe - west to thePortugueseeastern border, east toBelarus,north toEstoniaand south to coast ofNorth Africa.
  • The UK beam provides maximum signal (for reception with 45 cm (18 in) dishes) over the whole United Kingdom, Ireland, Benelux and northern France with a sharp roll-off of signal level outside this region, in close approximation of the UK beam ofAstra 2D.This enables channels to be broadcastfree-to-airbut with reception effectively constrained to theBritish Isles,and has been the basis for theFreesatfree-to-air United Kingdom platform.[5]
  • The strongest signals of the West Africa beam (receivable on 50 cm (20 in) dishes) coversCôte d'Ivoire,Burkina Faso,Ghana,Togo,Benin,Nigeriaandnorthern Cameroon,with additional "lobes" for parts ofGabonandCongo.Reception on larger dishes is available across the entire sub-Saharan west Africa region.
  • The Ka-band footprint is centred on France with coverage over all of western Europe.

History[edit]

The launch of Astra 2G was intended to be from theBaikonur CosmodromebyInternational Launch Services(ILS)Proton-Mlaunch vehiclea month earlier, on 28 November 2014 but technical problems with the launch vehicle caused it to be rolled back from the launch pad to undergo a component replacement. The satellite had arrived at Baikonur on 29 October 2014 after a delayed flight from Europe - an emergency landing of the transport aircraft in the city ofUlyanovskdue to engine trouble required replacement of the aircraft's engine and a two-day delay.[6]

Finally launched successfully on 27 December 2014, at 21:37:49 UTC,[7]the satellite was initially positioned at 21.0° East for three months and then tested at 43.5° East,[8][9]before moving to the Astra 28.2° East position in June 2015.[10]

On 18 June 2015, the first six channels, includingITVand Channel 4, began broadcasting from Astra 2G,[11]transferred from Astra 2E, Astra 2F and, in particular fromEutelsat 28A,which was some two years beyond its expected end-of-life and operating with some transponders considerably under power.[12]The final Eutelsat 28A channels, including theFreesatEPG data channel, transferred to Astra 2G on 29 June 2015.[13]

Active transponders[edit]

Below is a list of the television channels broadcast to the UK and Ireland from active transponders on Astra 2G as of May 2023:[14]

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