Spirent meets demand for satellite navigation system test needs with new GNSS simulator launch

The global navigation satellite systems (GNSS) testing solutions provider Spirent Communications has announced the launch of its enhanced GSS9000 Series GNSS constellation simulator. Providing significantly-improved capability, flexibility, and performance, Spirent says that the company has updated the GSS9000 Series to meet the demanding test needs of high-performance satellite navigation systems.

“We’re seeing the number of GNSS signals growing all the time, and an ever-increasing number of the receivers and systems we rely on every day are making use of these signals to improve accuracy, availability and continuity,” said Spirent Managing Director of Positioning, Martin Foulger. “That’s why it’s important that GNSS testing today and going forward reflects the reality of real-world situations, where simultaneous generation and testing of all signals is vital.”

Spirent explained that the enhanced GSS9000 Series addresses that need by doubling the number of supported channels (320 in a single chassis) while maintaining its full performance specification, including in key areas such as signal iteration rate and low latency, under maximum signal dynamics. These attributes, together with the ability to produce a comprehensive range of emulated multi-GNSS, multi-frequency RF signals, enables full and future-proofed testing of advanced applications.

Greater signal flexibility is also built into the enhanced GSS9000 Series, through its open API and flexible system architecture. This delivers a highly-sophisticated arbitrary waveform generator (AWG) capability. It also provides unrivaled coverage and support for all current Signal-in-Space Interface Control Documents (SIS ICDs), with even greater flexibility for both system and signal evolutions. This includes built-in and user-defined parameter controls for generation of non-current SIS ICD PRN codes, navigation data content, navigation data rate, chipping rate, edge shaping, and modulation types.

The enhanced GSS9000 Series also features sophisticated spoofing test capabilities, with full parametric control of multi-copy constellations, and trajectory spoofing/meaconing. Precise phase-aligned signal wavefront generation and multi-antenna/output capability is supported, creating the most capable anti-jam and anti-spoof test system available anywhere.
