The GSG-8 from Orolia is a Software-Defined GNSS Simulator that delivers the highest standard of Global Navigation Satellite System (GNSS) signal testing and sensor simulation performance in an easy-to-use, upgradable and scalable platform. This software-powered turnkey simulator supports multi-constellation, multi-frequency, and hundreds of signals with a 1000 Hz iteration rate. It provides high precision, resolution, and ultra-high dynamic motion. The simulator offers advanced GNSS jamming and spoofing options that allow the creation of threat scenarios required to meet the needs of mission-critical applications. It can be used for any development or integration project that requires sophisticated simulation capabilities.
The simulator allows testing of complex GNSS systems, such as Differential GNSS - Real-time Kinematics (RTK), receiver spoofing mitigation evaluation, multi-antenna vehicles, attitude measurements, and simple or complex arrays of GNSS receivers. It can also incorporate encrypted or proprietary signals with a comprehensive SDK, which allows signal generation of even the most sensitive signals.
The GSG-8 is powered by a Skydel simulation engine that can be programmed to simulate operations with all current and future GNSS signals. It also can simulate multiple synchronized trajectories (6 Degrees of Freedom (DoF) receiver) through multiple instances of the Skydel simulation engine. The Skydel simulator engine provides a flexible and scalable architecture to cover larger and more complex applications to test controlled reception pattern antennas (CRPA).
The GSG-8 can simulate hundreds of satellites in real-time, using off-the-shelf graphics cards (GPU) feature and can be configured using Python, C#, C++, and LabVIEW programming tools. It requires an AC supply of 100-240 V and consumes under 400 W of power. The simulator is available in a rackmount unit that measures 48.0 x 40.6 x 18.0 cm and is ideal for space trajectories, aerospace, custom PNT signals, and hardware-in-the-loop applications.
