GSS200D front view



GSS200D GNSS Multi-Frequency Interference Detector

The GSS200D is a GNSS interference/jamming detection system that operates simultaneously on multi-frequencies. It is able to detect, warn and capture any in interference within a deployment site. The captured interference is stored in I/Q format that can be replayed by a GSS7725.




Sim3D - Realistic Multipath and Obscuration Simulation

Multipath and signal obscuration can cause significant error in GNSS receivers. Multipath errors can vary from a few metres to hundreds of metres, depending on satellite geometry and environmental conditions. Accounting for these occurrences is vital in most positioning, navigation, and timing solutions.

Sim3D is an innovative 3D modelling system that creates a realistic environment for the testing of multipath and obscuration effects. Simulated GNSS signals interact with fully customisable models and environments, giving a level of detail, control, and realism not available in other solutions.

SimAUTO is a powerful upgrade for Spirent’s multi-channel simulators to provide lab test support for today’s multi-sensor In-Vehicle Navigation Systems (IVNS). It allows development and testing of automotive Dead Reckoning GPS receiver platform. SimAUTO is added on the SimGEN to emulate a vehicles wheel tick and output of a gyrosensor. Option to drive a single axis ratetable if required.



SimSAFE - Evaluate Vulnerability to Spoofing

SimSAFE is GPS/GNSS spoofing test solution. It uses GSS9000 or GSS8000 with SimGEN software suite to provide a realistic laboratory based spoofing test-bed. The system provides a legitimate test signal and spoofing attack signal for testing of receiver vulnerability and counter measures to spoofing attack.


This software package operates with Spirent’s flagship SimGEN software suite.



SimSENSOR - Test System for Hybrid Sensor Fusion for Indoor Positioning

SimSENSOR extends the capabilities of these Multi-GNSS simulators by simulating MEMS sensor outputs on a common trajectory with the simulated GNSS RF signals. The simulated MEMSs sensor outputs include user control of representative noise and errors (bias/drift).

This software package operates with Spirent’s flagship SimGEN software suite.


SimROUTE - Route-matched Trajectory Generation and Motion Visualization for faster testing

SimROUTE™ is an on-line tool which creates a Spirent-formatted User Motion File (*.umt) from a Google Maps defined route. SimROUTE™ is built upon a Google Maps Application Programming Interface (API) and as such shares many similarities with the standard Google Maps interface. The generated User Motion File can then be used in any SimGEN, SimREPLAYplus, scenario to provide the motion trajectory for the simulated vehicle.
