SES-2 is a communications satellite operated by SES. It was launched alongside the Arabsat-5C satellite.
Spacecraft
The platform is home to the first hosted payload, a mechanism by which governmental entities can fly modules on commercial satellites.{{cite web |url=http://www.spaceflightnow.com/news/n1111/04chirp/|title=Money-saving missile detection sensor powered on|publisher=Spaceflight Now|date=4 November 2011|access-date=11 April 2021}}{{cite web|url=https://www.spacenews.com/military/120413-hosted-success-af-plans-follow-on.html|archive-url=https://archive.today/20120913153647/http://www.spacenews.com/military/120413-hosted-success-af-plans-follow-on.html|url-status=dead|archive-date=13 September 2012|title=Hosted Success Air Force Plans Follow-On|publisher=SpaceNews}}{{cite web|url=http://www.space.commerce.gov/general/commercialpurchase/hostedpayloads.shtml |title=Hosted payloads|publisher=NOAA|url-status=dead|archive-url=https://web.archive.org/web/20140625160053/http://www.space.commerce.gov/general/commercialpurchase/hostedpayloads.shtml|archive-date=25 June 2014|access-date=11 April 2021}} {{PD-notice}} It carries 24 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.{{cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=2011-049A|title=Display: SES-2 2011-049A|publisher=NASA|date=5 April 2021|access-date=11 April 2021}} {{PD-notice}} It also carries the Commercially Hosted InfraRed Payload (CHIRP) for the U.S. Air Force. CHIRP demonstrates infrared detection technologies from geostationary orbit for missile warning applications.
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 launch vehicle. 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.
Mission
It entered into commercial service on 27 October 2011 in the 87° West orbital location.{{cite web|url=http://www.lyngsat.com/SES-2.html|title=SES 2 at 87.0°W|publisher=LyngSat|access-date=11 April 2021}} 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.{{cite web|url=https://cdn.shopify.com/s/files/1/0770/0935/files/Dreamcatcher_V_3.03_SL_5.5_User_Manual_1.pdf?6506786568900441680 |title=User's Guide to Setting Up and Using Othernet Dreamcatcher v 3.03|website=cdn.shopify.com|date=14 January 2019|access-date=11 April 2021}}
