Corporation (NYSE:HRS), a leading designer and supplier of highly
reliable satellite communications systems for government and
commercial applications, today announced the delivery of a
sophisticated antenna reflector and support boom for the N-STAR c
mobile communications satellite. The N-STAR c satellite, scheduled for
launch in mid-2002, will provide mobile telephony and data services
throughout Japan.

“We are proud to once again support Lockheed Martin on a
commercial satellite program,” said Bob Henry, president, Harris
Government Communications Systems Division (GCSD). “Our team of
engineers and designers used our latest reflector design automation
tools to quickly develop the design, reduce overall costs, and deliver
the reflector to the customer one month ahead of schedule.”

The reflector was manufactured at Harris facilities in Palm Bay,
Florida, as part of the N-STAR c geo-synchronous satellite’s C- and
S-band antenna system. The 5.1-meter diameter reflector structure and
its support boom weigh only 31 kilograms. The reflector, attached to
the satellite bus by the boom, includes a gold mesh reflective surface
and is stowed for launch like a simple umbrella. Once the satellite
achieves operational orbit 22,000 miles above Earth, ground
controllers send a command signal to the satellite to unfurl the
reflector using an electronic motor.

“Harris has produced more than 20 of these types of reflectors for
various applications, ranging in size from 5 to 15 meters in
diameter,” said Henry. “In fact, the very same reflector design for
N-STAR c can be scaled from two meters to more than nine meters to
give our customers a qualified design with minimum cost and quick

The N-STAR c satellite is being procured by NTT Mobile
Communications Network, Inc., NTT DoCoMo, Tokyo, Japan, which provides
digital cellular communications to most of Japan. Lockheed Martin
Commercial Space Systems, Newtown, Pennsylvania, is the satellite
prime contractor, integrator and communications payload supplier.
Orbital Sciences Corporation, Dulles, Virginia, provides its STAR
satellite bus for the project.

Harris GCSD conducts advanced research studies, develops
prototypes, and produces and supports state-of-the-art, highly
reliable communications and information systems that solve the
mission-critical communications challenges of its military and
government customers, and provides the technology base for the
company’s diverse commercial businesses.
