Registration is open for the 2026 GEO Symposium and GEO-21 Plenary, which will take place from 26 to 28 May 2026 in Geneva, Switzerland.
Held under the theme of ‘Investing in Earth Intelligence for a Resilient Future,’ the event will convene governments, space agencies, research organisations, private sector innovators, and development partners to explore how Earth intelligence (EI) can drive transformative, resilient solutions for people and the planet at a pivotal moment in the implementation of GEO’s Post-2025 Strategy.
The sessions will highlight user-driven solutions, open data and open knowledge practices, co-designed products and services, emerging partnerships, and investment opportunities that advance EI and GEO priorities.
The event will be livestreamed, for which registration is not required.

The Geoscience Australia Distinguished Lecture, “Putting the ‘Geo’ into Geospatial: Shaping the future of Positioning Australia,” will cover future direction of the program, reflecting on its past achievements and how it will meet future positioning demands.
As it moves beyond the establishment phase, the Positioning Australia program will strengthen its capability for continued future relevance. The program builds on opportunities arising from Australia’s geographic location, its technological capabilities, strong partnerships and internationally significant positioning infrastructure.
The adoption of PNT-based technologies is changing requirements for the systems delivering it. There is increasing awareness that society’s increasing reliance on modern technologies brings potential risks from vulnerabilities in PNT systems. This lecture will highlight how Positioning Australia will address these issues, including an often invisible risk: the reliance of PNT systems on a global geodesy supply chain that is increasing vulnerable.
Presented by Dr Martine Woolf, (Branch Head Positioning Australia), Ryan Ruddick (Director GNSS Informatics and infrastructure), Dr Anna Riddell (Director GNSS Analysis), Dr Lisa Hall (Director National Geodesy) and Phil Shears (Director PMO), the lecture will outline how Geoscience Australia aims to continue maximising return on Commonwealth investment in reliable positioning, modernising infrastructure, enhancing access and efficiency, and supporting national resilience and economic growth.
