Improving Jamming and Spoofing Robustness with Multi-Antenna GNSS Simulation


Improving Jamming and Spoofing Robustness with Multi-Antenna GNSS Simulation

Anti-jamming and anti-spoofing capabilities are becoming essential features of mission-critical GNSS receivers and dependent systems. In the military domain, the need to protect mission-critical PNT systems led to the development of adaptive antennas, which are now also increasingly used in commercial applications such as surveying, mining and autonomous vehicles. Adaptive antenna systems need to be thoroughly tested, particularly if they are to be used in safety and liability-critical contexts.

In this on-demand webinar, Spirent will explore the challenges of reliably testing adaptive antennas and provide guidance on establishing test requirements. They will also focus on the use of GNSS constellation simulators for the performance evaluation of advanced anti-jamming and anti-spoofing techniques of GNSS receivers. Topics covered will include:

Characterizing an adaptive antenna:

  • How adaptive antenna systems work
  • Challenges of testing adaptive antennas
  • Choosing a test method

Development of Array Receivers with Anti-Jamming and Anti-Spoofing Capabilities with Help of Multi-Antenna GNSS Signal Simulators:

  • Motivations & development process
  • Overview of the multi-antenna GNSS constellation simulator test set up
  • Jamming and spoofing scenarios: results and conclusions
