Boeing Electron
Dynamic Devices (EDD), a part of The Boeing Company’s [NYSE:BA] Space
and Communications business unit, recently received a $10 million
order from Orbital Sciences Corporation [NYSE:ORB] for amplifiers
that enhance the transmission of very low-level radio frequency signals
from orbiting satellites back to Earth.

The order marks the second contract for EDD’s linearized traveling
wave tube amplifiers (LTWTA), a recent product enhancement that is
added to satellites to ensure clearer communications. EDD is the leading
manufacturer of power and propulsion components for space applications.

The contract brings the total amplifiers ordered by Orbital to 96.
"In May, we were awarded a contract for 32 amplifiers, with an
option for an additional 64," said Charles Toups, general manager
of EDD. "In less than a year, Orbital has exercised its option
to purchase the additional LTWTAs for a total contract of more than
$15 million. This follow-on order shows that our customers have confidence
in us to provide quality, on-time products to meet their needs."
