GNSS Interference Detector System. Spirent Communications has announced a Robust PNT Test Framework that evaluates GPS and GNSS security vulnerabilities for positioning, navigation and timing (PNT) systems. 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. Spirent’s GSS100D Detector, developed in collaboration with Nottingham Scientific Ltd, enables detection, characterization and analysis of real GNSS threats. 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 and spoofing attacks, as well as space weather and other vulnerabilities for preventive troubleshooting. “Spirent wants to move beyond talking about the increase of GNSS vulnerabilities and offer a pragmatic approach to enable informed decision making when it comes to evaluating the impact of vulnerabilities,” said John Pottle, marketing director of Spirent’s Positioning Technology Division. “Through our Robust PNT Test Framework Spirent is pulling everything together to enable users to readily audit systems and take practical steps to improve resilience.” Spirent’s New GSS100D Detector, developed in collaboration with Nottingham Scientific Ltd., enables detection, characterization and analysis of real GNSS threats. The Robust PNT test framework is being demonstrated on the Spirent booth at ION GNSS+ 2015 this week. Spirent’s Robust PNT Test Framework.
