Based on Astrium's Eurostar E2000+ bus design, the geostationary orbit satellite broadcast digital radio programs in the L-Band frequency (1452–1492 MHz range).

[2] The satellite carried from 24 to 96 radio channels with on-board processing to allow variable bit rates from mono to CD audio quality transmission.

[4] In March 2010, WorldStar announced that it was considering disposing of its satellites by boosting them to a higher orbit and expending their remaining fuel.

[5] It was repurposed in 2010 for Samara's Yazmi online education company and then sold on in 2017 to CMMB/Hong Kong's Silkwave broadcasting operator, now part of CMMB Vision.

1worldspace would have used ETSI Satellite Digital Radio (SDR) open standard in the new European coverage beam.

Its last known status was in storage at EADS Astrium's and Thales Alenia Space facilities in Toulouse, France and Stevenage, U.K. Another satellite of identical design (known as WorldStar 4), for which long lead parts had been procured and partially assembled, was at one point also maintained in storage in Toulouse, France.
