GSG-7 Advanced GNSS Simulator

High Performance and Capability Made Easy

GSG-7 is revolutionizing the GNSS simulation industry with its easy-to-use simulation capabilities, extraordinary flexibility and rapid development cycles.

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. The GSG-7 is an advanced GNSS simulator, because it can accommodate nearly any configuration to conduct system testing and simulation.

Key Features:
  • Small size – 2U Rack-Mountable or Bench Top
  • All MF/MC Signals via Composite Port
  • Flexible software defined platform
  • Includes all GNSS constellations
  • Robust, integrated automation
  • 1000Hz simulation iteration rate
  • Integrated Low-Latency HIL
  • User-defined waveforms
  • All-in-view satellites simulation
  • Live sky time synchronization
  • On-the-fly scenario reconfiguration
  • 6 Degrees of Freedom (DoF) receiver trajectories
  • Flexible licensing
  • In-field software upgradability
  • High-end performance (precision, resolution, ultra-high dynamic motion)
  • Simulate hundreds of satellites in real-time using off-the-shelf graphics cards (GPU)
  • Comprehensive and intuitive API (Python, C# and C++ open-source client)
