05/07/2009 - Spirent® Communications and University of Nottingham Collaborate to Advance Multi-GNSS Technology

Paignton and Nottingham, England - (May 7, 2009) - Spirent Communications plc (LSE: SPT) the leading provider of navigation and positioning test solutions, and the GNSS Research and Applications Center of Excellence (GRACE), part of University of Nottingham's Institute of Engineering Surveying and Space Geodesy (IESSG), have expanded their already strong relationship to further advance the facility's satellite navigation signal test and simulation capabilities. This collaboration provides GRACE users access to a world-class Global Navigation Satellite System (GNSS) research laboratory and associated training services, an unsurpassed GNSS applications development environment and exceptional GNSS simulation, test-bed and testing facilities.

GRACE will use the advanced Spirent GSS8000 multi-GNSS hardware simulation system to simulate current and future GPS signals at L1, L2 and L5 frequencies, Galileo E1, E5 and E6 signals, and WAAS and EGNOS Space Based Augmentation System signals. The test system, which includes a two chassis, 16 channel GSS8000 system controlled by Spirent's SimGEN software, is one of the first to be delivered in the United Kingdom.

"This sophisticated Spirent solution enables GRACE to advance research activity in numerous application domains to prepare for the forthcoming GNSS signals," said Professor Terry Moore, head of the GRACE facility.

The new simulation system will be available to small and medium enterprises (SME) seeking to develop or test new applications. Providing access to the latest GNSS test facilities can be a major benefit to SMEs and it is anticipated that the system will build on GRACE's growing reputation in the field of GNSS research and development.

"Spirent has a long-term relationship with IESSG/GRACE and we are very pleased to be providing one of our multi-GNSS simulators to support this important new facility," said John Pottle, marketing director of Spirent's positioning technology division. "We look forward to continuing our work with Professor Moore and his team to support the research activities that the simulation system will enable."
