Future-Proof Your PNT Testing
With its embedded controller and compact design, the dedicated software-defined radio (SDR) architecture of the GSS7000 Global Navigation Satellite System (GNSS) Simulator combines power and space-saving efficiency for your labs. Its powerful, flexible simulation control software delivers intuitive scenario configuration and execution for all levels of test complexity; and with its modular design, users can customize and upgrade anytime, anywhere, enabling a proactive approach to evolving threats and growing expectations.
User-Friendly Simulation Control
The GSS7000 lets you choose between three levels of software, enabling you to balance budgetary requirements with the control you need over scenarios, signals, data logging and more.
Accessible Vulnerability Testing
Whether testing against complex jamming and spoofing attacks or qualifying systems for Radio Equipment Directive (RED) compliance, the GSS7000 enables comprehensive robustness testing for your PNT-enabled systems.
Low-Latency HIL Testing
Get robust, low-latency positioning, navigation, and timing (PNT) inputs for hardware-in-the-loop (HIL) configurations. Flexible operation and plug-and-play interoperability with HIL platforms enables advanced multi-sensor integration.
