Cascading effects of global positioning and navigation satellite service failures
Global navigation satellite systems (GNSS) provide vital timing and positioning services that are embedded across many sectors such as communication, transport and nance. Despite being an “invisible” infrastructure, GNSS is heavily interconnected with other services and is essential for maintaining “business as usual” activities. However, GNSS services can be affected both by natural and human-made threats, with practical implications for continuity plans and management strategies aimed at maintaining operational capacity. When building resilience to GNSS failures the possibility of cascading impacts must be taken into account. This report provides an essential overview of the most critical elements that could affect day-to-day operations, discussing the challenges around coping with such impacts and laying out guidance aimed at improving organisational resilience.
