Horizons-3e
Horizons-3e, also known as IS-H3e, is a high throughput geostationary communications satellite ordered by Horizons Satellites, a joint venture of Intelsat and SKY Perfect JSAT Group. The spacecraft is designed and manufactured by Boeing on the Boeing-702MP platform.
It is slated to be the sixth satellite of the EpicNG service, and will cover the Pacific Ocean Region from the 169° East longitude. It has a mixed C band and Ku band and is expected to launch in 2018 on an Ariane 5 rocket.
Horizons-3e is being designed and manufactured by Boeing on the Boeing 702MP satellite bus. It will have an estimated launch mass of 6 t (6.6 tons) and a design life of more than 15 years.
It is powered by two wings, with four panels each, of triple-junction GsAs solar cells. The 702MP platform was designed to generate between 6kW and 12kW.
It's payload will be the seventh high throughput EpicNG deployment. The EpicNG is characterized by the implementation of frequency reuse thanks to a mix of frequency and polarization in small spot beams. Not only applied to the classical HTS Ka band, but also applying the same technique in Ku band and C band. The EpicNG series also keep the use of wide beams to offer high throughput and broadcast capabilities in the same satellite.
