Abstract:	The vulnerability of Global Navigation Satellite Systems along with potential mitigation strategies has been the subject of discussion in many industry segments where the delivery of precise positioning or timing is of high importance. This paper provides an assessment of the difficulties and issues that currently exist in assessing the robustness of commercial GNSS devices against threats (including RF Interference, solar weather effects and Spoofing). Real world threats against GNSS are reviewed along with the expected evolution of threats as criminals seek to obtain financial gain from the use of jamming and spoofing to induce malfunctions in sophisticated tracking and/or timing equipment. This paper presents test results that show receivers behave differently in the presence of the same threat vectors. All receivers were affected, emphasizing the need to select appropriate mitigation approaches to suit the use case. The authors recommend the use of a risk assessment framework for Positioning Navigation and Timing (PNT) systems so that the robustness of the system can be assessed against realworld theat vectors – and the most appropriate (and cost effective) means of mitigation can be selected.
