Satellite to Launch This Year
Initial On-Orbit Testing Shows Satellite
Performing Nominally
Orbital ATK (NYSE: OA), a global leader in aerospace and defense
technologies, today 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. HYLAS 4 is the third GEOStar-3™ 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.
“The data from initial testing shows the satellite is in good
health and performing as expected,” said Amer Khouri, Vice
President of the Commercial Satellite business at Orbital ATK. “As
the third GEOStar-3 satellite to launch within three months, HYLAS
4 demonstrates Orbital ATK’s ability to develop and execute an
enhanced product that offers increased capability to meet our
customers’ emerging needs.”
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.
The GEOStar-3 platform is the newest, highest power and most
advanced platform in the flight-proven GEOStar product line. The
spacecraft bus features an increase in both battery capacity and
solar array power, enabling the GEOStar-3 to provide up to 8
kilowatts of power to the payload. The hybrid electric propulsion
system provides the benefits of higher power and greater payload
capability while maintaining cost-effective launches and a faster
path to orbit than all electric systems.
