Constellation Simulator Simulate signals from all GNSS and regional navigation Spirent’s GSS9000 constellation simulator. The Spirent GSS9000 Multi-Frequency, Multi-GNSS RF Constellation Simulator can simulate signals from all GNSS and regional navigation. It offers a four-fold increase in RF signal iteration rate (SIR) over Spirent’s GSS8000 simulator. The GSS9000 SIR is 1000 Hz (1 ms), enabling higher dynamic simulations with more accuracy and fidelity. It includes support for restricted and classified signals from the GPS and Galileo systems, as well as advanced capabilities for ultra-high dynamics. It can evaluate resilience of navigation systems to interference and spoofing attacks, and has the flexibility to reconfigure constellations, channels, and frequencies between test runs or test cases. Hardware changes can be made in the field, supported by the new on-board calibrator module. The GSS9000 is extensible and can support the widest range of carriers, ranging codes, and data streams for the Galileo, GPS, GLONASS and BeiDou systems, as well as regional/augmentation systems. Multi-antenna/multi-vehicle simulation for differential-GNSS and attitude determination, and interference/jamming and spoofing testing are also supported. GSS9000 Attributes 1000-Hz simulation iteration rate (SIR) and hardware update rate (HUR) enabling real-time remote control and trajectory delivery with extremely low latency and simulation of ultra-high dynamic motion 160 channels plus 640 embedded multipath channels across 10 independent frequencies in one chassis Single RF version and dual RF version for differential GNSS and multi-vehicle simulation 0.3 mm RMS pseudorange accuracy, 120,000 m/s relative velocity Highly flexible configurations selectable via a “cabinet” of license keys Complete portability of Spirent SimGEN scenarios In-field upgradeability Future-proofed for all advances in GNSS technology Spirent Federal, www.spirentfederal.com
