New reports provide guidelines for space weather events resilience and GNSS loss

Published: Tuesday, 11 February 2020 10:24

The UCL’s Mullard Space Laboratory and Institute for Risk and Disaster Reduction have released two operational reports that lay out guidelines for assessing and identifying organizational mitigation strategies to help prepare for space weather events,  global navigation satellite service failures, and their associated technological disruptions. 

The guidelines are the result of a collaboration between academics and practitioners, and they aim to provide an overview of the topic as well as practical actions for maintaining operational continuity. The reports have been structured to facilitate ease of reading in conditions of limited time availability, supporting the work of resilience officers, emergency planners and business continuity managers in public utility services, local authorities and the private sector. They refer directly to the latest ISO standards on business continuity management.

The reports are:

Cascading effects of global positioning and navigation satellite service failures

This report discusses the challenges around coping with the impacts of global navigation satellite service failures (GNSS) and lays out guidance to help improve organizational resilience to such events. The guidelines include the description of which dependencies and which cascading effects could be triggered with consequences to business as usual. Practical actions and compliance with ISO standards are also discussed.  Download at:

Organisational Resilience for Severe Space Weather

This report introduces severe space weather events and their possible impacts, including a process for assessing risk and a discussion of vulnerabilities that are common with other threats. Illustrative examples and an operational checklist for continuity planning and management are included. Download at:
