Software-Defined CRPA Test System

Protecting your GNSS systems from jamming and spoofing is more critical now than ever. This type of resilience is accomplished with an advanced GNSS Simulator capable of generating dedicated RF signals to test CRPA (Controlled Reception Pattern Antenna) architecture.

  • Scalable antenna configuration, supporting 2 to 16 multi-frequency antenna elements.
  • Modular all along the lifecycle.
  • Capable of supporting up to 4 GNSS bands simultaneously.
  • All GNSS bands : L1, L2, L5, E6, S band.
  • One GNSS output and one Interference output per antenna element.
  • Interference: Jamming, spoofing, and meaconing.
  • Simulate multiple threats simultaneously.
  • Dynamic transmitters with user-defined waveforms.
  • Shared LO across all Software Defined Radios.
  • Continuous phase synchronization and alignment monitoring.
  • Real-time semi-automated calibration tool.
  • No specific calibration needed after power cycle.
  • Reduced form factor (24U rack for typical 8 elements system).
  • Internal generation and distribution of low phase noise 10 MHz clock and 1-PPS signals.
  • Powered by Skydel (with GUI & API).
  • Hardware in the loop.
  • Quiet operation during simulation.
  • No specific calibration needed after power cycle.
