The demonstrated early warning capability of Global Navigation Satellite Systems (GNSS) to accurately, rapidly, and cost effectively measure deformation of the Earth’s surface and the response of the ionosphere to this deformation was the factual basis for the GNSS Tsunami Early Warning Systems Workshop (GTEWS) and this report. GTEWS 2017 was held in Sendai, Japan to review the principles of GNSS positioning, the geophysics of mega-thrust earthquakes, and GTEWS techniques in utilizing GNSS displacement and ionospheric imaging to advance global tsunami warning. This report explores the development history of GNSS Tsunami Early Warning Systems, their tsunami early warning technology and requirements, prototype networks, and the workshop findings and recommendations. 

This paper is a contribution to the 2019 edition of the Global Assessment Report on Disaster Risk Reduction (GAR 2019).
