Spirent Updated GNSS Constellation Simulator Focusing Positioning, Navigation & Timing testing

Industry’s most precise and realistic PNT test capability for high-dynamics vehicle simulation now available with Spirent’s enhanced 2 KHz update rate

Spirent Communications announces the addition of a premium enhancement to its GSS9000 Series GNSS constellation simulator. This new and unrivaled update rate capability offers the ability to recreate operations more precisely and realistically in order to reduce uncertainty in positioning, navigation and timing (PNT) testing.

Of particular benefit to high-dynamics applications, such as space missions and hypersonic vehicles, Spirent now offers 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.  The availability of an increased update rate will also deliver lower latency for hardware-in-the-loop (HIL) testing, strengthening the GSS9000’s position as the most precise and most realistic test instrument on the market.

“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.”

Continuing to raise the bar on highly flexible and scalable solutions, the GSS9000 Series has also been expanded to include:

  • Extended Scenario Duration – In a simulation environment, where initial and boundary conditions are key for a realistic representation of the mission, reducing the number of user inputs is essential. This new update will extend the available scenario duration to 65 days, using the same initial conditions for the simulation throughout the duration of testing, delivering uninterrupted high-performance simulation for longer. 
  • Enhanced Embedded Interference Capabilities –To provide greater power and flexibility in interference testing, Spirent has improved support for interference testing on wide spectrum signals, increased bandwidth resolution and repetition rates, and added variable bandwidth control on additive white Gaussian noise (AWGN).

Spirent has a rich history and unrivaled performance in PNT testing, that combines a deep understanding of the market with a continuing commitment to improving test capabilities,” said Spirent Product Line Manager for High-End Applications, Ricardo Verdeguer Moreno. “With the new update rate, not only are testing and proof of concept more realistic, but customers can reduce uncertainty by providing more accurate operations – and do so without impacting system performance.”

The enhancements will be available to new and existing Spirent customers beginning in Q2 2021. For more information about Spirent’s GSS9000 enhancements and capabilities, visit the GSS9000 Series GNSS constellation simulator product page.
