Orbital ATK-built communications satellite launched

Orbital ATK (NYSE: OA), a global provider of aerospace and defense technologies, has announced the HYLAS 4 commercial communications Ka-band satellite, built by the company for Avanti Communications Group plc (Avanti), was successfully launched aboard an Arianespace rocket, the company said.

HYLAS 4 is the third GEOStar-3â„¢ satellite to be completed by Orbital ATK and will provide high speed and affordable broadband communications to Europe and Africa.

Liftoff occurred at 5:34 p.m. EDT from Kourou, French Guiana. The satellite separated successfully from the launch vehicle approximately 35 minutes into the mission after reaching its targeted orbit. Orbital ATK completed the satellite´s initial post-launch health check and configuration in preparation for orbit-raising procedures and in-orbit tests. The spacecraft handover to Avanti is anticipated in April.

HYLAS 4 was built in Orbital ATK´s satellite manufacturing facility in Dulles, Virginia. It is a hybrid electric propulsion and all Ka-band high-throughput satellite that sets a new standard for affordability and payload flexibility in its class. The satellite will extend Avanti´s Ka-band coverage across Europe, the Middle East and Sub-Saharan Africa. Furthermore, additional capacity can be provided through four steerable beams, which can address existing regions or new regions such as Latin America.
