GSG-7 GNSS Simulator

High-Performance GNSS Simulation for Advanced Testing & Integration

The GSG-7 GNSS Simulator is a high-performance, software-defined GNSS simulation platform designed for defence, space, and autonomous vehicle applications. With a 1000 Hz simulation iteration rate, all-in-view satellite simulation, and real-time synchronization, GSG-7 enables precise, repeatable testing of navigation and timing systems in the most demanding environments.

Powered by the industry-leading Skydel simulation engine, GSG-7 supports multi-constellation, multi-frequency GNSS simulations, including all current and future GNSS signals.

A comprehensive SDK enables the integration of custom and proprietary waveforms, ensuring flexibility for sensitive and advanced use cases.
