21 Oct Global Navigation Space Systems: reliance and vulnerabilities
Royal Academy of Engineering (UK) (RAEng) 2011
In an ever more connected world, society’s reliance on high integrity positional, navigational and timing (PNT) data is growing. The Academy’s study has identified an increasing number of applications where PNT signals from GNSS are used with little, or no, non-GNSS based back-ups available. The trend is for GNSS to be used in a growing number of safety of life critical systems. Unfortunately, the integrity of GNSS is insufficient for these applications without augmentation. Non-GNSS based back-ups are often absent, inadequately exercised or inadequately maintained. The recommendations of this report include raising awareness, analysing impact, increasing resilience and a number of particular policy responses.
