on Astra 2B were used by Sky UK, BSkyB to provide the Sky UK, Sky Digital television services of standard and high-definition television (HDTV) and digital radio. Astra 2B could also provide backup capacity, substituting for one or more transponders across the whole 10.70-12.75 Hertz, GHz range used by Astra satellites in the Astra 19.2°E and Astra 28.2°E orbital positions. A third, steerable beam provides 8 transponders in the 12.50-12.75 GHz range for Internet and telecommunications services in West Africa. This aspect of the satellite was originally the commercial responsibility of SES World Skies, SES New Skies (now incorporated into SES S.A.). Following the launch of Astra (satellite), Astra 2F to 28.2° East, in February 2013, Astra 2B started its planned move from that position to Astra 19.2°E, to serve alongside Astra 1KR, Astra 1L, Astra 1M, and Astra 2C, arriving in position by 27 February 2013. In January 2014, Astra 2B moved to the Astra 31.5°E orbital position, pending the delayed launch of Astra 5B to that position and stayed there as back-up until it was moved back to 19.2° East in December 2016. In June 2017, it was moved west at approximately 0.6°/day to arrive alongside NSS-7 at 20° West in August 2017. From April 2018 to July 2018, Astra 2B was moved east at 0.6°/day to Astra 19.2°E.Real Time Satellite Tracking And Predictions
