With CDMA customers in
25 countries here on Earth, Sirius Communications NV announced today that its
technology will move into space as part of the NASA space shuttle and
International Space Station wireless video system.
Sirius provided flight
hardware, consulting services, development support and software for the
Anticipated first flight is for mission build 4A scheduled in late

Video data from a helmet-mounted camera is provided to crewmembers inside
the Space Shuttle Orbiter.
The extra vehicular camera video system has three
cameras integrated into the astronauts’ helmet.
These are controlled by a
command signal transmitted from the International Space Station or the

The camera technology is provided by Broadcast Sports Technology, Inc.,
utilizing technology from the Racecam used in NASCAR and IRL racing.
Broadcast Sports is developing the RF camera system including the payload bay
s-band antenna arrays, transceivers, and the ERCA RF camera system.

“The power flux density of the Sirius’ CDMA solution is undetectable on
the earth and by Low Earth Orbit satellites also active in the same frequency
bands,” said Michael Katzmann, president of Broadcast Sports.
“The close to
ideal performance of the Sirius Direct Sequence Spread Spectrum approach
allows a reliable command link to the Extravehicular Mobility Unit Radio
Frequency Camera Assemblies.”

Sirius Communications provides Broadcast Sports Technology with flight
hardware, consulting services, development support and software.
Communications has a long track record of delivering technology for the
European Space Agency ESTEC.

“By electing the CDMA modulation scheme from Sirius Communications,
