Detailed Analysis of the Star One Fleet
Star One C1: Technical Specifications and Launch
The Star One C1 represents a significant component of the fleet. It was launched on November 14, 2007, at 22:06 UTC. The mission faced initial hurdles, with delays occurring on November 9 due to launch vehicle issues and again on November 12 because of problems with the launch pad.
Built by Alcatel Alenia Space using the Spacebus 3000 B3—a standardized satellite platform—the C1 weighed approximately 4,100 kg (9,000 lb) at the time of launch. It is equipped with a versatile array of transponders, which are devices that receive a signal and retransmit it at a different frequency to enable communication. Specifically, it carries 28 C-band, 16 Ku-band, and one X-band transponder.
