11/11/2008 - Spirent® Communications Announces World's First Quasi-Zenith Satellite System for RF Simulation


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

Tokyo - (November 11, 2008) - 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 GSS8000 now supports QZSS system in addition to 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 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, Spirent 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.
