AMC-21, or GE-21, is an American
Spacecraft and mission design
AMC-21 is based on a STAR-2 satellite bus that provides 4.4 kilowatts of power for the communications payload. The platform will support a 15-year on-orbit mission life.[3] It carries 24 Ku-band transponders at 36 MHz, which will be used to broadcast television signals to Canada, United States, Mexico, the Caribbean, and Central America.[2]
Manufacture
Thales Alenia Space was the prime contractor for AMC-21, and provided the satellite's communications payload. The STAR-2 bus was subcontracted to Orbital Sciences Corporation, as were integration and testing of the satellite.[3] As prime contractor, Thales Alenia Space delivered the completed satellite to SES Americom.[4]
Launch
AMC-21 was launched, along with the
Mergers and acquisitions
In September 2009, SES Americom merged with SES New Skies to form SES World Skies, to which all of its operational satellites, including AMC-21, were transferred.
