Spirent Communications Supports Quazi Zenith Satellite System

Spirent Communications, a provider of navigation and positioning test solutions, announced that its GSS80000 RF constellation simulator now supports the Japanese Quasi Zenith Satellite System (QZSS).

 

The Quasi-Zenith Satellites System is a joint government-private section program, currently being developed with three navigation satellites that are placed in multiple orbital planes, so that the system makes it possible to provide accurate satellite positioning service covering the entire area of Japan. Since one of the satellites will be placed at the Zenith over Japan, even mobile users who are traveling can communicate and send or receive high-quality content without any interference.

 

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.

 

It now supports QZSS system in addition to GPS, Galileo, GLONASS and SBAS. Support will be initially for L1 C/A code and L1 SAIF QZSS signals and the company is planning to add other QZSS signals later as the market develops.

 

This add-on accurate support has for the first time, allowed the developers of QZSS systems-based receivers, systems and applications to have a solution that offer 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," said 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," added Pottle.

 

Spirent believes that only laboratory simulation can ensure controlled repeatable testing which will help in exploring both nominal and off-design conditions. Here, by following a structured test approach, Spirent customers can test multi-GNSS receivers, systems and applications, resulting in shorter development times and improved performance.
