5/5/2008 - Spirent® Announces GSS8000 High Dynamics GPS Simulator

New Spirent GSS8000 Offers Higher Signal Accuracy, Dynamics & Signal Quality

PAIGNTON, UK - Spirent Communications plc (LSE: SPT) the leading provider of navigation and positioning test solutions, today announces improved high dynamic capabilities on its new Spirent GSS8000 simulation system. The Spirent GSS8000 is designed for use in the most demanding applications, and is capable of simulating ultra-high dynamics with industry leading accuracy.

The Spirent GSS8000 supports up to 20,000g signal dynamics, up to 120,000 m/s velocity and 50Hz (4ms) processing rates. Motion data can be generated using Spirent's on-board vehicle models or using real-time high-rate host vehicle trajectory data over a remote interface. Spirent's implementation supports full 6 degrees-of-freedom (6DOF) trajectory data. Low-latency hardware-in-the-loop capability is standard with synchronization and timing facilitated via 1 PPS in/out and 10MHz clock inputs.

In addition, the Spirent GSS8000 is designed to support Spirent's range of options and extensions for testing advanced navigation and positioning systems. These include a range of GPS+inertial test interfaces, classified testing capabilities, interference effects, jamming signals and multi-element adaptive antenna (CRPA) antenna electronics units.

"The Spirent GSS8000 offers our customers the test capability they demand, for both today and tomorrow's programs," commented John Pottle, marketing director, Positioning Technology division, Spirent Communications. "We are taking the simulator performance to the next level with the Spirent GSS8000, while maintaining Spirent's full range of options and classified testing capabilities that our customers have come to rely on, such as classified testing and full test support for future M-code receiver programs."

Spirent's products are sold in the US and Canada by Spirent Federal Systems, a wholly owned subsidiary of Spirent Communications. You can learn more about the GSS8000 at their booth at IEEE/ION PLANS 2008 May 5-8, 2008 in Monterey, CA.
