Spirent Communications has announced its Robust PNT Test Framework that evaluates GPS and GNSS security vulnerabilities for Positioning, Navigation and Timing (PNT) systems. Its new GSS100D Detector has been developed in collaboration with Nottingham Scientific Ltd. which enables detection, characterization and analysis of real GNSS threats.
Threats to GNSS and related PNT applications are more orchestrated and coordinated, with the motivation to disrupt or cause financial loss. The technology to disrupt GPS has also become much more accessible, resulting in GPS vulnerability gaining attention at hacker conventions.

The Robust PNT Test Framework will be used by technology, system and application developers where PNT is critical. Spirent’s framework enables threats to be detected in the field, taken into the lab and re-synthesized along with GPS and other GNSS signals. In addition, Spirent’s threat intelligence library of actual and typical threats provides a wide range of GNSS segment errors, spoofing attacks as well as space weather and other vulnerabilities for preventive troubleshooting.
The Robust PNT test framework is being demonstrated this week at the Spirent booth at ION GNSS+ 2015.
