The GSS9000 Series from Spirent is a Multi-Frequency, Multi-GNSS Simulation System that supports GPS, Galileo, GLONASS, BeiDou, QZSS and NavIC GNSS constellations. It has an unrivaled update rate that offers the ability to recreate operations more precisely and realistically to reduce uncertainty in positioning, navigation and timing (PNT) testing.
The GSS9000 system consists of a Signal Generator Chassis and dedicated C50r Host Unit running Spirent’s SimGEN™ scenario definition and simulation control software.
The GSS9000 Signal Generator Chassis consists of one or more RF Channel Banks. An RF Channel Bank consists of 2 cards - a digital signal generator card and an RF up-converter card. Each RF Channel Bank is licenced to support; 4, 8, 12, 16 or 32 separate channels. Each RF Channel Bank is capable – at any one time – of supporting any number of licensed GNSS constellations in the same frequency band.
The Signal Generator Chassis is controlled by a dedicated, rack-mountable C50r SimGEN Host. It is a multi-processor/core system, configured with a mixed Operating System (OS) environment (Linux and Windows® 10 Professional for Embedded Systems ESD [Virtualisation Only]). This combination of processing power and dual OS provides the perfect platform to enable the GSS9000’s new bench-mark performance levels and to support Spirent’s SimGEN™ scenario definition and simulation control software application.
The simulator is powered by SimGEN™ Software for test scenario definition, execution, data management and GNSS RF constellation simulator command and control. It uses the latest state-of-the-art technology designed specifically for GNSS signal simulation to produce a comprehensive range of emulated RF signals with industry-leading flexibility, fidelity, performance and reliability. The simulator allows constellations and channels to be temporarily enabled on a time-limited rental basis. This is particularly useful if the system is to be used for short to medium-term projects requiring an additional constellation and/or additional satellite channels for a defined period.
