Astra 2G is one of the Astra communications satellites owned and operated by SES, launched to the Astra 28.2°E orbital slot in December 2014, at 03:37:49 Baikonur time.
Astra 2G is positioned at 28.5°E (part of the Astra 28.2°E orbital slot) and is the last of three 'second generation' satellites launched to this slot to replace the first generation Astra 2A, Astra 2B, Astra 2C and Astra 2D craft originally positioned there between 1998 and 2001, and it joined Astra 2E and Astra 2F launched in 2013 and 2012, respectively.
Astra 2G carries both Ku-band and Ka-band payloads and will deliver broadcast, VSAT and broadband services to Europe, the Middle East and Africa, and will also provide the ability to connect West Africa to Europe via Ka-band. 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 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 700,000 IPTV homes in the UK and Ireland, in particular for channels from the major UK digital satellite TV platforms, BSkyB and Freesat.
Astra 2G also supports SATMED, a satellite-based e-health platform developed by SES and supported by the Luxembourg Government 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.
Astra 2G has three Ku-band downlink beams and one Ka-band beam:
