Advanced anti-jam testing

Controlled reception pattern antennas (CRPAs) are being used to counter the significant threats posed by malicious jammers (beam-nulling) and improve signal reception (beam-forming). Testing these systems has several defined stages, and requires powerful, flexible and very accurate test equipment. From conducted wavefront testing to realistic over-the-air scenarios, Spirent’s industry-leading solutions are powering the next generation of robust PNT technology.

Conducted wavefront testing

Testing the electronics and software behind the antenna is a key element of effective CRPA testing. Spirent’s GSS9000 is the industry’s leading test platform – designed and built specifically for the most challenging GNSS performance and resiliency tests. Supporting all existing civilian signals, restricted GPS/Galileo signals, and the bespoke design of customers’ own non-ICD GNSS signals, the GSS9000 features:

  • Intuitive antenna reception gain and phase pattern control for different carrier frequencies
  • Remote interface suitable for HIL customer receiver integration
  • Proven ionospheric, tropospheric, multipath and terrain obscuration models
  • Real-time data logging and streaming of signal, time, control, vehicle and trajectory parameters
  • Proven multi-box capability and scalability to support any future requirements - seamlessly

Over-the-air CRPA testing

The final stages of CRPA testing and development is often over-the-air (OTA) testing for angle of arrival (AOA) verification. Spirent’s GSS9790 builds on the leading GSS9000 platform, adding the capability to individually control up to 10 independent but synchronous transmitters using just a single signal generator, creating a realistic representation of the satellite skyplot and trajectories. In addition, the GSS9790 fully supports synchronisation with additional boxes where required, maintaining the same high-level performance. The GSS9790 features:

  • Up to 10 individual RF outputs per signal generator box
  • Scalable - capability to join multiple signal generators where more than 10 outputs are required
  • Intuitive antenna reception gain and phase pattern control for different carrier frequencies
  • Remote interface suitable for HIL customer receiver integration
  • Proven ionospheric, tropospheric, multipath and terrain obscuration models
  • Real-time data logging and streaming of signal, time, control, vehicle and trajectory parameters
