Spirent GSS8000 Multi-GNSS constellation simulator

"A powerful flexible choice for R&D applications, supports multi-system, multi constellation GNSS testing"

The GSS8000 series has been designed to meet all the demanding requirements of research and development teams involved in satellite navigation and positioning systems.

Due to its modular design, the GSS8000 can be readily adapted to the requirements of different applications. Up to 3 RF carriers, selected from a range of constellations and signals, can be accommodated in a single signal generator chassis.

A GSS8000 system comprises a controller computer running Spirent’s powerful simulation software SimGEN, and a signal generator configured to meet specific test needs. Multiple chassis can be combined to form an integrated, coherent signal generator if more signals or outputs are required. An extensive range of system extensions allows users to tailor their system to their specific needs, today and in the future.

Standard capabilities enabled through SimGEN include simulation of atmospheric effects, multipath reflections, terrain obscuration, antenna reception gain and phase patterns, differential corrections, trajectory generation for land, air, sea and space vehicles and comprehensive error generation.

An easy to use graphical user interface (GUI) allows modification of a wide range of variables from pre-set defaults, enabling the user to focus their time on the areas of test important to them. Complete scenarios are readily shared between systems, supporting collaborative activities and speeding up the R&D cycle.
