AMC 12 / Astra 4A / Star One C12 / NSS 10

AMC 12 (Astra 4A) [Alcatel]

This series of satellites based on the new generation Spacebus-4000C3 platform has been originally ordered by GE-Americom as GE 1i, 2i, 3i, 4i and 2E. They were renamed to AMC after SES took over Americom and some were cancelled in this process.

AMC 12 features 72 C-Band transponders; it will provide digital TV, telecommunications, data and video transmissions, connecting over the Atlantic Ocean North and South America, Europe and Africa.

AMC 12 was originally ordered as GE 1i, and AMC 22 was originally GE 3i, but this one was cancelled.

In early 2004, AMC 12 was transferred to Worldsat LLC, a new subsidiary of SES Americom as Worldsat 2. In early 2005 few weeks before launch, it was renamed AMC 12 again.

24 transponders on AMC 12 have been contracted by SES ASTRA which will market this capacity in Africa under the name Astra 4A. 18 transponders will be operated by Star One as Star One C12.

In March 2007, the satellite was transferred to SES New Skies and named NSS 10.
