Safran Skydel GSG-7 Advanced GNSS Simulator

The Safran Skydel GSG-7 GNSS simulator 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 Safran Skydel GSG-7 is ideal for development and integration projects that require high performance and an increased number of constellation licenses and satellites in view for a single antenna or trajectory. 

Safran Skydel GSG-7 supports multi-constellation and multi-frequency GNSS simulations. Powered by our industry-leading Skydel simulation engine, GSG-7 can be programmed to simulate operations with all current and future GNSS signals. 

Safran Skydel GSG-7 can also incorporate proprietary signals with a comprehensive SDK, which allows the generation of even the most sensitive signals. 
 

GSG-7: High Capability. Software-defined

GSG-7 is redefining GNSS simulation with its easy-touse, advanced simulation capabilities and extraordinary flexibility. Using the robust and innovative 1000Hz Skydel software engine and commercial-off-the-shelf (COTS) software-defined radios (SDRs), GSG-7 easily outperforms the competition. It can accommodate nearly any configuration to conduct system testing and simulation. 
 

GSG-7 Benefits

  • Flexible software-defined platform
  • Future proof design
  • Supports all GNSS constellations
  • Robust, integrated automation
  • Easy and powerful HIL integration
  • User-defined waveforms
  • Supports aerospace simulations:


- Ultra-high dynamics trajectories 

- High iteration rates 

- Orbit simulations 

The leveraging of COTS SDRs and GPUs permits easy customization and maintenance, while reducing costs. More affordable than other options on the market, the GSG-7 delivers precision and performance for your critical programs. In addition, the GPU provides signal generation processing power, with 150 to 225 signals (depending on signal complexity) generated simultaneously. 
 

Automate in Seconds

The unique and modern architecture of the Skydel simulation engine provides an extensive application program interface (API) to configure and control all aspects of the simulator. The open-source client API is available in a wide range of programming languages such as Python, C#, C++ and LabVIEW. Moreover, all human and machine interactions with the simulator are instantly recorded and can be exported as executable python scripts, which greatly simplifies the work of test engineers who want to automate or expand the simulator’s capabilities. 

Furthermore, all scripts, configurations and scenarios created on a Skydel-powered simulator, are portable to any other Skydel platform.
