L-3 Communications’ Products Launched On 100th Shuttle Mission – Wide Array of L-3 Technology for the International Space Station

L-3 Communications announced today that two of its
divisions, L-3 Communication Systems-East in Camden, NJ, and L-3 Space
and Navigation in Teterboro, NJ, moved a step closer to significant
milestones with the successful launch of Space Shuttle Discovery
(STS-92) last night at 7:17 p.m. EDT (23:17 GMT) from Kennedy Space
Center.

STS-92, which marks NASA’s 100th Space Shuttle mission, will
include the first installation of L-3 products aboard the
International Space Station. These products will provide critical
communication links and attitude control functionality to the
International Space Station.

The products designed and manufactured by L-3’s Communication
Systems-East division include the Ku-Band communication subsystem, the
S-Band communication subsystem, and the external video subsystem. The
Ku-Band communication subsystem will be used for high-speed
transmission of video and scientific data to earth. The S-Band
communication subsystem will allow for transmission of two-way voice
communication and telemetry data. The external video subsystem
provides visual surveillance of exterior Space Station areas to help
monitor assembly operations, payload integration and astronaut safety
during space walks.

The current mission will install components of both the Ku-Band
and S-Band communication subsystems. L-3 Communications celebrated the
milestone associated with this mission by sending a contingent of
design engineers to attend the launch. Additional components are
scheduled to be launched and installed over the next 2 years.

Products designed and manufactured by L-3’s Space and Navigation
business include the Control Movement Gyros which provide attitude
control for the ISS, and the Integrated Electronics Assembly which
controls the Solid Rocket Boosters Subsystems including ignition and
separation, and the Range Safety Distributor, which is the control
electronics for the Shuttle Destruct System.
