We are pleased to inform the geodetic community that the International GNSS Service (IGS) Annual Technical Report is now available and includes the SIRGAS annual report, which presents the main activities, progress, and contributions made by our organization over the past year.

The IGS Technical Report is a key reference publication for the international geodetic community. Each edition documents the activities of analysis centers, working groups, projects, and partner organizations that contribute to the development, maintenance, and improvement of the global GNSS infrastructure and geodetic reference frames, providing a comprehensive overview of the achievements of the scientific and technical community.

In this edition, the SIRGAS report highlights the progress made in strengthening the Geodetic Reference Framework for the Americas, the activities carried out by its working groups, the evolution of the regional infrastructure, the processing and analysis of GNSS data, as well as the international cooperation and capacity-building initiatives that drive the growth of geodesy in the region.

The inclusion of the SIRGAS annual report in this publication reflects the commitment and joint effort of the institutions, analysis centers, national agencies, and professionals that make up our community, whose collaborative work allows us to maintain and strengthen a modern, accurate, and sustainable geodetic infrastructure at the service of science, engineering, and society.

We thank all the institutions and specialists who make these results possible and continue to contribute to the development of SIRGAS and the International GNSS Service (IGS).

As part of the opening ceremony of the IGS Workshop 2026, held in Santiago, Chile, Colonel Gustavo Caubarrère, President of SIRGAS and Chair of the Scientific Organising Committee (SOC), delivered a welcome message to the international geodetic community.

In his address, he emphasized the importance of cooperation among organizations, institutions, and specialists worldwide to continue strengthening the global geodetic infrastructure, a fundamental element for the development of precise reference frames, Earth monitoring, and support for numerous scientific, technological, and land management applications.

He also highlighted the role of the International GNSS Service (IGS) and SIRGAS in promoting international collaboration, knowledge exchange, and the development of technical capabilities that contribute to the advancement of geodesy for the benefit of the global community.

The IGS Workshop 2026 brought together researchers, professionals, and representatives from international organizations to share the latest advances in geodesy, GNSS, and reference frames, solidifying its position as one of the leading scientific gatherings in the field.

At the IGS Workshop 2026, the international geodetic community gathered in Santiago, Chile, to share scientific advancements, strengthen international cooperation, and discuss the challenges facing global geodetic infrastructure.

One of the keynote addresses was delivered by Dr. Catalina Cáceres, who presented a comprehensive overview of the evolution of SIRGAS and its close collaboration with the International GNSS Service (IGS). During her presentation, she highlighted the main advances achieved in geodetic processing, the strengthening of the regional reference framework, and the initiatives that promote a more accurate, reliable, and sustainable geodetic infrastructure for Latin America and the Caribbean.

The presentation also addressed the region’s future challenges, emphasizing the importance of international cooperation, capacity building, and technological innovation to ensure the continuity and modernization of the geodetic infrastructure that supports scientific and engineering applications, global change monitoring, and disaster risk management.

As part of this publication, we are sharing a carousel summarizing the main topics covered during the conference.
