SES-12 is the largest and most powerful all-electric satellite ever produced. It is based on the highly reliable Eurostar platform in its E3000e variant, which uses electric propulsion for orbit raising (EOR). The related mass saving enables SES-12 to combine two high-capacity missions, equivalent to two conventional satellites, in one satellite.
To fulfil its dual mission, SES-12 features both wide beams and high throughput spot beams to serve diverse connectivity needs.
The communications payload incorporates state-of-the-art solutions, in particular, multi-beam antennas linked to a digital signal processor, which enable a multitude of basic spectral channels to be allocated to various beams in a completely flexible manner.
The satellite will provide expansion and replacement capacity to serve the data, mobility, government and video sectors in the Asia-Pacific region.
SES-12 will operate in the Ku and Ka-bands with a total of 76 active transponders and eight antennas. It will have a launch mass of 5,400 kg and an electrical power of 19 kW. It will operate in geostationary orbit at the 95° East location and has been designed to remain in service for more than 15 years.
