    - Spirent's GSS8000 Adds QZSS Support to Existing GPS, Galileo & GLONASS 
Capabilities



    Spirent Communications plc (LSE: SPT) the leading provider of navigation
and positioning test solutions, today announces the world's first RF
constellation simulator that supports the Japanese Quasi Zenith Satellite
System (QZSS). Spirent GSS800 now supports QZSS system in addition to GPS,
GPS, Galileo, GLONASS and SBAS.

    The QZSS system, currently under development, plans to offer three
navigation satellites in high-altitude orbits to improve navigation
performance in areas of Japan that prove difficult with GPS alone. Spirent
will initially provide support for L1 C/A code and L1 SAIF QZSS signals and l
add other QZSS signals as the market develops. For the first time, developers
of QZSS systems-based receivers, systems and applications have a solution
that provides controlled, repeatable test signals, essential for accurate
testing.



    "This announcement demonstrates Spirent's commitment to continue to
invest in support of the evolving test needs of the GNSS community,"
commented John Pottle, marketing director at Spirent's positioning technology
division. "The first QZSS satellite is planned for launch in 2009. Our
customers can now test receivers, systems and applications that will use the
QZSS signals. In addition, Spirent's systems will combine QZSS with GPS and,
if required, Galileo and GLONASS to provide a complete GNSS test bed."



    Only laboratory simulation can ensure controlled repeatable testing that
explores both nominal and off-design conditions. By following a structured
test approach, our customers can test multi-GNSS receivers, systems and
applications, resulting in shorter development times and improved
performance. The Spirent GSS8000 simulation system design allows for a wide
variety of configurations from GPS L1 right up to comprehensive multi-RF
output and/or multi-constellation test systems.



    You can learn more about Spirent's new QZSS test capabilities at the
Spirent booth # 9 & 10 at the International symposium on GPS/GNSS in Odaiba,
Tokyo, 10-14 November 2008.
