Countering jamming, spoofing and interference

The threats to GNSS-based positioning, navigation and timing are increasing in number and in prevalence. The technology to disrupt GPS has become much more accessible. Examples include increases in websites selling low-cost “personal protection” jammers and GPS starting to gain attention at hacker conventions.

Spirent offers a practical Robust PNT framework to audit receiver, system or application resilience. We can provide test systems for you to use as well as advice and professional test services. Use the resources below to learn how to measure and improve the robustness of your PNT system in the face of jamming, spoofing and other types of interference, and discover the solutions Spirent has to offer.

Quantify the impacts of GNSS vulnerabilities

Spirent maintains the only global navigation and timing threat intelligence database – including real detected interference threat waveforms, GNSS system events and errors, natural effects such as multipath and atmosphere and examples of spoofing attack vectors.

Robust PNT framework

Spirent’s Robust PNT framework enables informed decision making to improve resilience.

  • GSS200D Interference Detector to detect disruptive RF interference
  • Threat Intelligence Library of actual and typical threats
  • PT TestBench to regenerate RF vulnerabilities in the lab
  • Audit and test services
