Intelsat EpicNG High -Throughput Satellite Platform

Horizons 3e Successfully Launched; Completing Intelsat EpicNG’s Global Coverage

 First Global C-and Ku-band High-Throughput Satellite Platform

Built by Boeing and based on the award-winning Intelsat EpicNG design, Horizons 3e will bring high throughput satellite solutions in both C-and Ku-bands to Asia and the Pacific Ocean region from its orbital slot at 169ºE. The satellite will complete Intelsat EpicNG’s global coverage and provide broadband, mobility and government customers with unmatched performance, resiliency and redundancy. Horizons 3e is expected to commence service in the first quarter of 2019.

Horizons 3e is the first Intelsat EpicNG satellite to feature a multiport amplifier that enables power portability across all Ku-band spot beams. With the multiport amplifier, power can be adjusted to each beam to meet customer throughput demands.   This enhanced, advanced digital payload features full beam interconnectivity in three commercial bands and significant upgrades on power, efficiency and coverage flexibility.  By matching satellite power usage to traffic demands, aeronautical and maritime mobility, fixed and wireless network operators, corporate enterprise and government customers can leverage the additional efficiency improvements to expand their network and applications across the Asia Pacific region.  In addition to the power sharing technology, Horizons 3e provides additional resiliency to the IntelsatOne Flex managed service platform, for use in enterprise, government and mobility applications.




Benefits of the Intelsat EpicNG Platform

High Performance. Open Architecture.

Intelsat EpicNG offers you a major design breakthrough for increased satellite throughput and performance. This new constellation of high-throughput spacecraft marks the progressive evolution of our global network, incorporating new C, Ku and Ka spot beams into our fleet to create differentiated solutions for your applications.
