Make it real: Developing a test framework for PNT systems and devices

OPENING GRAPHIC

Tests of the robustness of commercial GNSS devices against threats show that different receivers behave differently in the presence of the same threat vectors. A risk-assessment framework for PNT systems can gauge real-world threat vectors, then the most appropriate and cost-effective mitigation can be selected. Vulnerabilities of GNSS positioning, navigation and timing are a consequence of the signals’ very low... read more
