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

Spirent Communications plc ( (LSE: SPT), the leading
provider of navigation and positioning test solutions, today announced the
launch of the Spirent GSS6700 Multi-GNSS Constellation Simulator
( 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

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 RD
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.
