LONDON, MARCH 16, 2021 – Spirent Communications plc (LSE:SPT), the world leader in global navigation satellite system (GNSS) testing solutions, today announced the addition of premium enhancements to its GSS9000 Series to further extend its position as the industry’s most precise and realistic GNSS constellation simulator. Among the enhancements, a doubling of the update rate capability means the GSS9000 series now offers unrivalled ability to recreate operations more precisely and realistically, reducing uncertainty in positioning, navigation and timing (PNT) testing.

The latest developments provide the GSS9000 series with the ability to run simulations at a software and hardware update rate of up to 2 kHz, improving accuracy of the simulated trajectory without compromising performance. This is of particular benefit to high-dynamics applications, such as space missions and hypersonic vehicles. The increased update rate also delivers lower latency for hardware-in-the-loop (HIL) testing, further reinforcing the GSS9000’s position as the industry’s most accurate and realistic test instrument.

“Our dedicated hardware and powerful software solutions are built specifically with PNT test in mind – to improve accuracy, increase flexibility and provide high-performing systems to meet customer needs,” said Spirent Director of PNT Simulation, Adam Price. “These latest enhancements to the GSS9000 continue to raise the bar for highly flexible and scalable solutions that enable our customers to stay ahead of their competition.”

Other enhancements to the GSS9000 Series include:

“Spirent’s leadership in GNSS testing comes from the combination of our unrivalled heritage and deep understanding of the PNT market, alongside our continuing commitment to improving test capabilities for customers,” said Spirent Product Line Manager for High-End Applications, Ricardo Verdeguer Moreno. “By working closely with customers, we are able to better understand the challenges they face, and these latest enhancements to the GSS9000 series demonstrate how we are continuing to help customers reduce uncertainty by providing more accurate operations, without impacting system performance.”

The enhancements to the Spirent GSS9000 series will be available to new and existing customers at the beginning of Q2, 2021. For more information, visit the GSS9000 Series product page, while US government and prime contractors should contact Spirent Federal for more details.
