Spirent Communications, a provider of navigation and positioning test solutions, has launched the GSS6700 Multi-GNSS constellation simulator for global navigation satellite system (GNSS) testing.

The GSS6700 offers a GPS test capability and support for the Russian Glonass system and the planned European Galileo system.

John Pottle, marketing director of Spirent’s Positioning Technology division, said: ‘Many people are actively looking at adding more signals from different satellite constellations to improve navigation and positioning device performance.

‘The new GSS6700 is designed for testing devices that use commercial multi-GNSS signals,’ he added.

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 research-and-development applications.

For environments where repeat testing using the same test cases is needed – verification testing, for instance – Spirent’s Simreplay software is available.

Simreplay can be specified with a web-based or onboard 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, according to the company.

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.
