'''Horizons-3e''', also known as '''IS-H3e''', is a [[High-throughput satellite|high throughput]] [[geostationary orbit|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 Satellite Development Center|Boeing]] on the [[Boeing 702|Boeing-702MP]] platform.<ref name=gsp-horizons3e /><ref name=satbeams-horizons3e />
It is the sixth satellite of the Epic<sup>NG</sup> service, and covers the Pacific Ocean Region from the 169°&nbsp;East longitude.<ref name=spacenews-20160229 /> It has a mixed [[C band (IEEE)|C band]] and [[Ku band|K<sub>u</sub> band]]<ref name=satbeams-horizons3e /> and was launched in 25 September 2018 on an [[Ariane 5]] rocket.<ref name=tp-20170424 />
==Satellite description==
'''Horizons-3e''' was designed and manufactured by [[Boeing Satellite Development Center|Boeing]] on the [[Boeing 702|Boeing 702MP]] [[satellite bus]]. It has an estimated launch mass of {{convert|6|tonne|abbr=on}} and a design life of more than 15 years.<ref name=gsp-horizons3e />
It is powered by two wings, with four panels each, of [[Triple-junction solar cell|triple-junction]] [[Gallium arsenide|GsAs]] [[solar cell]]s.<ref name=boeing-backgrounderintelsat /><ref name=gsp-horizons3e /> The 702MP platform was designed to generate between 6&nbsp;kW and 12&nbsp;kW.<ref name=boeing-backgrounderintelsat />
Its payload is the seventh [[High-throughput satellite|high throughput]] Epic<sup>NG</sup> deployment. The Epic<sup>NG</sup> 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 [[High-throughput satellite|HTS]] [[Ka band|K<sub>a</sub> band]], but also applying the same technique in [[Ku band|K<sub>u</sub> band]] and [[C band (IEEE)|C band]]. The Epic<sup>NG</sup> series also keep the use of wide beams to offer high throughput and broadcast capabilities in the same satellite.<ref name=intelsat-wpepicngplatform />
==History==
'''Horizons Satellite''' was originally an equal share [[joint venture]] with [[PanAmSat]]. It ordered its first satellite, [[Horizons-1]]/[[Galaxy 13]] from [[Boeing]] in middle 2001 and successfully launched it on October 1, 2003.<ref name=gsp-galaxy13 /> During 2005, PanAmSat was taken over by [[Intelsat]], but the relationship continued and on August 30, 2005, Horizons Satellite ordered a [[GEOStar-2]] based satellite, [[Horizons-2]], which successfully launched on December 21, 2007.<ref name=gsp-horizons2 /><ref name=businesswire-20050830005673 />
In July 2009, [[Intelsat]] became the first customer of the [[Boeing 702|Boeing 702MP]]  platform, when it place an order for four spacecraft, [[Intelsat 21]], [[Intelsat 22]], [[Intelsat 27]] and the first Epic<sup>NG</sup> satellite, [[Intelsat 29e]].<ref name=boeing-backgrounderintelsat />
On June 7, 2012, Intelsat announced the Epic<sup>NG</sup> platform. It would improve available bandwidth thanks to the use of frequency reuse and polarization and feature spot and wide beams, enabling high bandwidth and broadcast applications on a backward compatible way. The first two satellites would be Intelsat 29e and Intelsat 33e.<ref name=intelsat-news20120607 /> On September 4, 2012, Intelsat and Boeing announced that Intelsat 29e, the first Epic<sup>NG</sup> satellite, would be made by Boeing on the 702MP platform, completing the 2009 order of four such satellites.<ref name=intelsat-news20120904 />
In May 2013 Intelsat ordered a further four 702MP-based Epic<sup>NG</sup> satellites, [[Intelsat 32e]], [[Intelsat 33e]] and two as of August 2016 unnamed spacecraft. And in July 2014 a sixth Epic was ordered, [[Intelsat 35e]].<ref name=boeing-backgrounderintelsat /><ref name=boeing-pr20140708 />
In  a deal that took 18 months, on November 4, 2015 Intelsat and JSAT announced their fourth joint satellite, after [[Horizons-1]], [[Horizons-2]] and [[Intelsat 15]]/[[JCSAT-85]], '''Horizons-3e'''. It would be the seventh [[High-throughput satellite|high throughput]] satellite in the Intelsat fleet, and complete Intelsat Epic<sup>NG</sup> family of satellites by covering the Pacific Ocean Region with [[C band (IEEE)|C band]] and [[Ku band|K<sub>u</sub> band]].<ref name=intelsat-pr20151104 /><ref name=intelsat-pr20151112 /><ref name=satellitetoday-20151104 /><ref name=satellitetoday-20151116 />
