SES 2

NSSDCA/COSPAR ID: 2011-049A

Description

SES 2, a communications satellite, was launched on 21 September 2011 from Kourou at 21:38 UT by an Ariane 5 rocket. The satellite weighed 3.2 tonnes and will join four other Orbital-built spacecraft in the SES fleet to provide service for North America. It carries 24 active C-band and 24 Ku-band transponders of 36 MHz capacity. Six of the channels in each band can be cross-strapped to the opposite band, enabling new service capability. The SES 2 satellite will generate approximately 5.0 kW of payload power and will have two 2.3 m deployable reflectors. It will be stationed at 87-degrees West longitude.

It also carries the Commercially Hosted InfraRed Payload (CHIRP) for the U.S. Air Force. CHIRP will demonstrate infrared detection technologies from geosynchronous orbit for missile warning applications.
