Spirent GSS7000
Flexible and Powerful Multi-GNSSConstellation Simulator System

Spirent GSS7000
Flexible and Powerful Multi-GNSS Constellation Simulator System
The GSS7000 series of multi-GNSS, multifrequency simulators from Spirent for GNSS testing
which can grow with your evolving needs.

Key Features• GPS, GLONASS, BeiDou, Galileo, QZSS andSBAS supported• Up to 256 channels in a system, flexibly allocatedacross constellations• Field upgrade minimises downtime as yourneeds grow• Portable scenarios facilitate collaboration• Class leading accuracy, fidelity and reliability• Save and compare DUT data
• Receiver antenna pattern modelling• Import motion from logged NMEA
• Selection of scenario generation and simulation
control software available— SimGEN®: Comprehensive constellation,
propagation and vehicle modelling withflexible data capture— SimREPLAYplusTM: Import remote trajectory,
edit time, date and position— SimTEST TM: Test control with route-matchedtrajectory data from Google Maps®
— Single Channel Utility: Simulate one channel
per constellation with specified signal
parameters. Switch signals and codes on/off
via remote command

GSS7000 supports GPS, GLONASS, BeiDou,Galileo, QZSS and SBAS L1/E1/B1, L2/B2, L5/E5,and L6 signals

Users working in the development, integration orverification of multi-GNSS products for consumer
device and precision civil PNT applications are able
to verify product performance under a range ofcontrolled, repeatable conditions.

The GSS7000 offers exceptional accuracy, fidelity
and authentic GNSS signal emulation across theentire series ensuring true performance at every
test stage.
A full range of hardware integration signals areprovided including 1PPS in / out, 10MHz in / outand hardware trigger.
The GSS7000 Multi-GNSS Simulator is supported
by a range of scenario generation and simulator
control software packages including Spirent’s
feature-rich SimGEN. Each software package
has a range of capabilities from the all-inclusive
SimGEN to packages more suited to production orintegration / verification test processes.
SimGEN offers a complete and flexible scenario
generation capability including control of theconstellations, propagation, terrain obscuration,antenna patterns, multipath, vehicle trajectory anda range of error models.
SimREPLAYplus enables the user to define vehicle
motion remotely as well as adding the ability to edit
the time, date and position. SimREPLAYplus allows
users to generate scenarios locally.
SimTEST offers easy to use yet precise capabilities
for general testing, including generation of routematched trajectory data from Google Maps
Single Channel Utility offers the capability tosimulate one channel per constellation via either
remote commands or the dedicated user interface.
Perfect for many production test scenarios.
