Star One C1 is a Brazilian communications satellite. It was launched on 14 November 2007 by an Ariane 5ECA carrier rocket, as part of a dual-payload launch with Skynet 5B. It was built by Thales Alenia Space, based on the Spacebus-3000B3 satellite bus.[1] It is operated by Star One, a subsidiary of Embratel.
It was launched atop an Ariane 5-ECA rocket at 22:06 UTC on November 14, 2007. This launch had previously been delayed from November 9 due to a problem with the rocket, and then from November 12 due to a problem with the launch pad. Star One C1 was built by Thales Alenia Space based on a Spacebus 3000 B3 platform. It has 28 C-band transponders, 14 Ku-band transponders and one X-band transponder, and weighed about at launch.[2]
