Horizons-3e, also known as IS-H3e, is a high throughput geostationary communications satellite ordered by Horizons Satellite, a joint venture of Intelsat and SKY Perfect JSAT Group. The spacecraft is designed and manufactured by Boeing on the Boeing-702MP platform.[2][3]
It is the sixth satellite of the EpicNG service, and covers the Pacific Ocean Region from the 169° East longitude.[4] It has a mixed C band and Ku band[3] and was launched in 25 September 2018 on an Ariane 5 rocket.[1]
Horizons-3e was designed and manufactured by Boeing on the Boeing 702MP satellite bus. It has an estimated launch mass of 6 t (6.6 tons) and a design life of more than 15 years.[2]
It is powered by two wings, with four panels each, of triple-junction GsAs solar cells.[5][2] The 702MP platform was designed to generate between 6 kW and 12 kW.[5]
Its payload is 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.[6]
