Protecting Position, Navigation and Timing Systems & Applications

Robust PNT Framework

Practical Solutions to Predict Impacts from Typical Threats

Evaluate and improve the robustness of positioning, navigation and timing systems

The frequency and severity of threats to GPS and GNSS systems is evolving from unstructured experiments to more organised attacks that are better funded and more motivated. 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 test services provided by us.

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.
