PAIGNTON, United Kingdom, July 16 /PRNewswire/ --

- Spirent GSS6700 offers a flexible solution for R&D, integration and 
verification testing of GPS, GLONASS and Galileo devices

Spirent Communications plc (http://www.spirent.com/) (LSE: SPT), the
leading provider of navigation and positioning test solutions, today
announced the launch of the Spirent GSS6700 Multi-GNSS Constellation 
Simulator (http://www.spirent.com/Solutions-Directory/GSS6700.aspx)for 
global navigation satellite system (GNSS) testing. The GSS6700 offers not 
only GPS test capability but also support for the Russian GLONASS system and 
planned European Galileo system.

"Many people are actively looking at adding more signals from different
satellite constellations to improve navigation and positioning device
performance," commented John Pottle, marketing director of Spirent's
Positioning Technology division. "Spirent has significant experience in
developing and offering test systems which combine GPS, GLONASS and Galileo
signals. The new GSS6700 is designed for testing devices that use commercial
multi-GNSS signals. Each GSS6700 benefits from Spirent's proven heritage of
technical excellence and reliability."

The GSS6700 is available with a range of software capabilities designed
to suit differing test requirements. SimGEN is Spirent's fully flexible
simulator software suite and would typically be used in technology
development and R&D applications. For environments where repeat testing using
the same test cases is needed, for example verification testing, Spirent's
SimREPLAY software is available. SimREPLAY can be specified with web-based or
on-board limited scenario generation capability.

In addition to GPS, GLONASS and Galileo commercial signals, the GSS6700
supports augmentation system and interference testing. Space Based
Augmentation System (SBAS) support is a standard offering with GPS systems.
Options include dynamic and flexible interference signal generation, vehicle
sensor emulation coherent with GNSS and Local Area Augmentation System (LAAS)
support. Spirent also offers a range of test scenarios to reduce test
scenario development time.

Simulation of GPS, GLONASS and Galileo is acknowledged as the best way of
testing GNSS receiver, system and application performance. Only laboratory
simulation can ensure controlled, repeatable testing that explores both
nominal and off-design conditions with easy access to test data. By following
a structured test approach, Spirent's customers can test multi-GNSS
receivers, systems and applications resulting in reduced costs, shorter
development times and improved performance.
