SES-3 is a communications satellite operated by SES World Skies, then by SES S.A.

Spacecraft

SES-3 was built by Orbital Sciences Corporation (OSC), and is based on the Star-2.4 satellite bus. It is equipped with 24 C-band, and 24 Ku-band transponders, and at launch it had a mass of 3,112 kg (6,861 lb). It has a design life of fifteen years, however it was launched with enough fuel to operate for at least sixteen years, if its systems are still functional.^[3]

Launch

It was launched on 15 July 2011 at 23:16:10 UTC on a Proton-M / Briz-M launch vehicle, the launch was arranged by International Launch Services (ILS), since Baikonour, Site 200/39 alongside the KazSat-2 satellite.

Mission

It is positioned at 103.0° West orbital location over North America, replacing AMC-1. Clients include E. W. Scripps Company, In Demand, Pay-per-view, Ion Television, Mood Media, NBC and QVC.^[4]
