• Notes

• WorldSpace was a digital satellite radio network that covered the whole of Africa as well as parts of Asia and Europe. It consisted of two satellites, Afristar and AsiaStar. There were also plans to expand the service to Latin America (AmeriStar). WorldSpace broadcast in the L-band (1467-1492 MHz). Three beams (footprints) with 50 BC channels each were available per satellite, whereby each BC channel could provide up to 8 sub-channels for digital radio programs as well as multimedia services.

  WorldSpace was founded in 1990 by Ethiopian-American businessman Noah A. Samara and worked with many industry partners including Alcatel Space, Fraunhofer Institute for Integrated Circuits, Micronas, Rohde & Schwarz.

  In 2008, Worldspace filed for bankruptcy and in 2009 the satellites were sold to Yazmi. Yazmi uses the satellites to distribute educational content to special e-readers in Africa.

  The two satellites, which were launched around the year 2000 (1997/2001), have now exceeded their planned lifespan of 12 years. However, the operator Yazmi assumes that the satellites will continue to function for a further 6 years, as none of the existing replacement components have been used to date.
