Ku-band FSS and BSS Commercial Communications Satellite
FACTS AT A GLANCE
Mission Description
The THOR 5 satellite was developed and built for Telenor Satellite Broadcasting AS (TSBc) to provide
broadcasting and interactive services to the Nordic countries, Europe and the Middle East. The Telenor
THOR 5 spacecraft replaced the THOR II satellite at the 0.8 degrees West Longitude orbital position, and
provides additional capacity, further expanding TSBc's business base.
THOR 5 provides regional Ku-band coverage for Fixed Satellite Services (FSS) and Broadcast Satellite
Services (BSS). There are 15 active FSS transponders and nine active BSS transponders for xed
coverage regions. In addition, ve more active BSS transponders are routed through a steerable
antenna that can be pointed toward any other region on Earth visible from the 0.8 degrees West
Longitude.
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.
