Spirent Communications today unveiled improvements to the high dynamic capabilities on its Spirent GSS8000 GNSS simulation system.

The GSS8000 supports up to 20,000 g signal dynamics, up to 120,000 m/s velocity, and 50 Hz processing rates, according to Spirent. Motion data can be generated using its on-board vehicle models or using real-time, high-rate host vehicle trajectory data over a remote interface; the GSS8000 supports full 6 degrees-of-freedom trajectory data. Low-latency hardware-in-the-loop capability is standard with synchronization and timing facilitated via 1 PPS in/out and 10 MHz clock inputs, the company said.

The Spirent GSS8000 is also designed to support the company's range of options and extensions for testing advanced navigation and positioning systems. These include a range of GPS plus inertial test interfaces, classified testing capabilities, interference effects, jamming signals, and multi-element adaptive antenna electronics units, according to the company.

Spirent also recently added GLONASS L2 test capability to the GSS8000 simulation system, which already supported GLONASS L1 simulation.
