Why Choose the GSS9000?

To develop positioning, navigation and timing systems for military, space,

and other high precision applications you require comprehensive, highly

sophisticated testing. The updated GSS9000 Series multi-frequency,

multi-GNSS RF constellation simulator sets a new standard of excellence

in future-proofed simulation for R&D and performance testing.

designed specically for GNSS signal simulation, the GSS9000 Series

produces a comprehensive range of emulated RF signals with industry-

leading exibility, delity, performance and reliability.

Extensions and Options

Increasingly, GNSS receivers and sensors do not operate in isolation. The GSS9000 has been designed to

operate with all of Spirent’s extensive range of options and system extensions, ensuring all additional signals are

reproduced coherent with GNSS.

SimINERTIAL™: Operational

performance of an integrated

GPS/inertial (IGI) system can be

established in the laboratory using

real-time emulation of the inertial

sensor outputs. All signals are

coherently generated to exactly

match the simulated vehicle

trajectory. Typical inertial sensor

performance can be represented by

a sensor error model driven by the

simulated motion, with appropriate

coefcients entered by the user.

SimMNSA™: Supporting GPS

Directorate approved MNSA M-Code

testing with SimMNSA.

SimMCODE™: AES M-Code testing

with SimMCODE, and server-based

SDS M-Code testing via a SimMCODE

extension.

SimCLASS™ / SimSAAS™: Providing

SA/A-S simulation for the testing of

SAASM equipment with Y Code.

Sim3D™: Realistic multipath and

obscuration testing by simulating the

impact of the 3D local environment

on GNSS signals.

GSS7765: Offering a broad range

of interfering signal options,

which can be used to represent an

array of threat sources, supports

noise generation with variable

bandwidth, and can be congured to

support multiple fully independent

interference sources.

SimREMOTE™: Extend the

GSS9000’s native Ethernet remote

control facility to include GPIB and

SCRAMNet. Allows input and output

of simulation, signal control and

external 6DOF motion data.

SimSAFE™: Evaluate the vulnerability

of a receiver to deliberate spoong

or meaconing attacks, and assess the

effectiveness of mitigation techniques

and strategies.

Flexibility and Connectivity

The GSS9000 is designed for real-

world testing environments, with a

wide range of both analogue and

digital interfaces.

— Low level RF outputs are

supplemented by high level RF

inputs and outputs for monitoring

and signal injection

— Digital interfaces include IEEE-

488, Ethernet and SCRAMNet GT

— Extensive timing, trigger and

control access
