HYLAS 2
Ka-band Commercial Communications Satellite
FACTS AT A GLANCE
Mission Description
The HYLAS 2 satellite carries 24 active Ka-band user beams and six gateway beams, and produces
approximately 5.0 kilowatts of payload electrical power. The Ka-band spot beams provide two-way
communications services to facilitate high-speed delivery of data to end-user applications such as
corporate networking, broadband Internet access, business continuity services and video distribution.
Using the HYLAS 2 spacecraft, Avanti provides its data and video services to Eastern and Southern
Africa, Eastern Europe and the Middle East. In addition, the spacecraft is equipped with a steerable
spot beam, also operating at Ka-band, which provides coverage anywhere on Earth that is visible to the
satellite.
The GEOStar™ Advantage
Orbital’s highly successful Geosynchronous Earth Orbit (GEO) communications satellites are based on
the company’s GEOStar spacecraft platform, which is able to accommodate all types of commercial
communications payloads and is compatible with all major commercial launchers. The company’s
GEOStar product line includes the GEOStar-2 design, which is optimized for smaller satellite missions
that can support up to 5.0 kilowatts of payload power. Orbital has also developed the higher-power
GEOStar-3 spacecraft design, delivering the next increment of payload power for applications between
5.0 and 8.0 kilowatts, allowing Orbital to offer its innovative and reliable satellite design to the
medium-class of communications satellites.
