CRPA Test GPS/GNSS Simulators

Based on the proven SDX simulator, we offer two flexible solutions for testing CRPA: SDX Wavefront and SDX Anechoic. SDX-based GNSS simulators tailored for custom projects and R&D needs are also available.

Example of a SDX Wavefront Hardware Configuration
Simulate the behaviour of a CRPA antenna with SDX Wavefront, upward of 8 antenna elements.

SDX Wavefront
Wavefront GNSS Simulator

SDX Wavefront combines high performance with SDX Advanced Jammers to enable unlimited test scenarios. It leverages the multi-instance synchronization features of SDX to enable simulation scenarios including high-dynamics trajectories (GNSS and non-GNSS). SDX Wavefront generates phase-synchronized signals in real time, enabling to realistically simulate the behaviour of a CRPA antenna.

SDX Wavefront features:

  • High Performance (Accurate phase synchronization under 1º RMS)
  • 8+ antenna elements
  • Large number of dynamic transmitters + user-defined waveforms (via Advanced Jamming)

Use SDX Wavefront for:

  • Tests scenarios integrating both dynamic receiver’ and interferences’ positions
  • Lab installations where anechoic chamber is not practical
  • Testing CRPA processing unit (without antenna)

SDX Anechoic
Anechoic Chamber GNSS Simulator

SDX Anechoic is a complete system featuring the SDX GNSS simulator, advanced calibration tools and full hardware. SDX Anechoic is designed to speed up chamber calibration setup and reduce the multiplication of hardware systems.

Based on COTS hardware, it supports 32+ RF outputs to provide a cost-effective CRPA testing solution for RF labs equipped with an anechoic chamber.

SDX Anechoic configurations feature:

  • Up to 32 RF Outputs
  • Automatic Antenna Mapping
  • Automatic Time Delay Calibration
  • Automatic Power Loss Calibration
  • Support for GPS encrypted codes, via BroadSim Anechoic
  • Very high jamming power (>110 dB of J/S)

Use SDX Anechoic for:

  • Comprehensive testing including the antenna
  • Testing unlimited number of antenna elements
  • Testing static positions only

About Adaptive Antennas

Adaptive antennas, also called CRPA, or sometimes anti-jam antennas, will play a greater role in the future GPS/GNSS landscape. Their unique capabilities help increase resilience to GNSS signals impairments, such as ever-increasing multipath, accidental interferences, or even RF attacks. Once reserved solely for the military domain, adaptive antennas are entering the civilian market and are poised to bring their benefits to the fields of aerospace, ground transportation, and autonomous driving, as well as various others.

Engineers working with GNSS systems that employ CRPAs and multi-element antennas need special test systems since they need to replicate very specific test conditions that are impossible with live signals. We created SDX Wavefront and SDX Anechoic to address those needs. Like all other SDX configurations, CRPA simulator based on SDX provide COTS hardware benefits: configuration flexibility and cost-effectiveness.

CRPA Antenna
Anti-Jam antennas use techniques, such as nulling or beam-forming, to mitigate the effects of interfering signals.
