Spacecraft

The platform is home to the first hosted payload, a mechanism by which governmental entities can fly modules on commercial satellites.[3][4][5] 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 generates approximately 5.0 kW of payload power and has two 2.3 m deployable reflectors.[6]

It also carries the Commercially Hosted InfraRed Payload (CHIRP) for the U.S. Air Force. CHIRP demonstrates infrared detection technologies from geosynchronous orbit for missile warning applications.[6]

Launch

SES 2, a communications satellite, was launched on 21 September 2011 from Centre Spatial Guyanais, Kourou at 21:38:00 UTC by an Ariane 5 ECA rocket. The satellite weighed 3200 kg and join four other Orbital Sciences-built spacecraft in the SES fleet to provide service for North America, Latin America and the Caribbean. It is stationed at 87° West longitude.[6]

Mission

It entered into commercial service on 27 October 2011 in the 87° West orbital location.[7]

This satellite is used to transmit the updating Othernet archive to the small lightweight Othernet receiver stations designed to eventually provide news, weather, educational and other media to communities with no access to the internet.[8]
