GNSS Simulator Enhanced for High-Dynamics Vehicles, Space Missions, HIL Testing

Spirent Communications has added premium enhancements to its GSS9000 Series GNSS simulator, doubling the update rate 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.

Other enhancements to the GSS9000 Series include:

• Extended Scenario Duration – In a simulation environment, where control and repeatability are key for a realistic representation of the mission, reducing the number of user inputs is essential. The new update will extend the available scenario duration to 65 days, using the same initial conditions for the simulation throughout the duration of testing to deliver 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).
