Spirent Communications, provider of testing solutions for positioning and navigations systems, has introduced the Spirent GSS9000 Multi-Frequency, Multi-GNSS RF Constellation Simulator. The GSS9000 offers a new benchmark in performance, capability and flexibility that includes the ability to simulate signals from all GNSS and regional navigation systems.

The GSS9000 offers new levels of performance, enabled by a four-fold increase in RF signal iteration rate (SIR) over Spirent’s current GSS8000 product. The GSS9000 SIR is 1000Hz (1ms), enabling higher dynamic simulations with even more accuracy and fidelity, Spirent said. It also includes support for restricted and classified signals from the GPS and Galileo systems as well as advanced capabilities for ultra-high dynamics. The GSS9000 can evaluate resilience of navigation systems to interference and spoofing attacks.

GSS9000 has the flexibility to reconfigure constellations, channels and frequencies, between test runs or test cases. In addition, the GSS9000 has been designed to be backward compatible, enabling the use of existing test cases and remote control/motion from existing Spirent simulators. Hardware changes can now be done in the field, supported by the new on-board calibrator module.

“The GSS9000 raises the performance bar and addresses the future challenges of improving accuracy and resilience for end users of GNSS technology,” said Martin Foulger, managing director of Spirent’s Positioning division. “The GSS9000 solution is a result of almost thirty years of unrivalled expertise, innovation and leadership.”

The GSS9000 is extensible and can support the widest range of carriers, ranging codes and data streams for the GPS, GLONASS, Galileo and BeiDou GNSS systems as well as regional/augmentation systems. Multi-antenna/multi-vehicle simulation, for differential-GNSS and attitude determination, and interference/jamming and spoofing testing are also supported.
