More information

Safran’s GSG-8 Gen2 is an evolution of the popular GSG-8. An expert-level positioning, navigation, and timing test solution offered through Safran’s family of Skydel-based simulators.

The GPU-based GSG-8 Gen2 simulator delivers the highest standard of GNSS signal testing in an easy-to-use, turnkey form factor supporting the growing need for location-aware applications and systems that require navigation or timing. With 6 front-facing high-quality RF outputs and a combined one, the GSG-8 Gen2 GNSS simulator covers the entire GNSS bandwidth and features high-end performance with a 1000 Hz simulation iteration rate, high dynamics, real-time synchronization, and simulation of all-in-view satellite signals.

The GSG-8 Gen2 is ideal for development, NavWar testing, and integration projects that require very high performance and an increased number of constellations and satellites in view, and multi vehicle / multi antenna scenarios.

With the GSG-8 Gen 2 Simulator, you can generate RF signals to simulate how your receiver device will react in the real world, under the simulation parameters that you set. Control every aspect of your simulation, including 6 Degrees of Freedom (DoF) receiver trajectories, multipath signals, advanced jamming and spoofing, as well as atmospheric interferences.

Advantages

Advanced Jamming & Spoofing

The jamming and spoofing capabilities allow you to simulate all types of interference that can occur in the real world – whether benign or malicious. You can set the power level, interference signal type, spoofing signals, location, antenna pattern and trajectory for each transmitter. You’ll be able to generate in-band and out-of-band jamming signals, with no additional hardware required.

 

Multi-Signal/Frequency

With multiple satellite constellations – both global, local, and LEO — providing signals for navigation and geospatial applications, the number of signals and frequencies being emitted, augmented, and echoed is staggering. Simulating all these aspects is a challenge for FPGA-based simulators which are not capable of generating an increased number of signals in view.
Skydel-based systems like the GSG-8 have successfully overcome this technological hurdle by leveraging the immense computational power of modern GPUs (Graphics Processing Units) to simulate well up to 2000 GNSS signals with maximum flexibility across multiple bands – simultaneously!

 

Multi-Vehicle/Antenna

When testing unmanned aerial vehicles (UAVs) such as drones, or aircraft
(with one antenna per wing), or spacecrafts, GNSS simulators can generate
a signal to represent multiple antennas and/or vehicles. But how those
antennas/vehicles interact with others and perform in GPS and GNSS-denied
environments can make all the difference in their performance. And many
applications rely on multiple antennas for positioning and heading.
From a single GSG-8 Gen2, users can run and control multiple instances
(running on the same hardware), each one representing an independent
trajectory, vehicle, or antenna – each with its own output connector.

 

LEO PNT

LEO PNT GNSS constellation are being launched into space with increased
frequency, and with it comes a great deal of promise (security, accuracy,
indoor GNSS). Like GNSS, LEO PNT relies on GNSS simulation to be developed
and used – from the signal definition to receiver integration in systems.

The GSG-8 Gen2 is a state-of-the-art LEO PNT signal simulator. No other
platform is able to generate the high number of signals needed for LEO PNT
simulations in addition to legacy GNSS signals, threats, and multipaths. This
high capacity also allows the GSG-8 Gen2 to generate S-Band signals in
addition to the above.
