SYMPOSIUM 2026

The SIRGAS 2026 Symposium

The SIRGAS Executive Committee is pleased to invite the entire Scientific and Technological Community related to Geodesy and Earth Sciences to participate in the SIRGAS 2026 Symposium

Montevideo – Uruguay

03 al 06 de noviembre de 2026

Goals

Promote the implementation of the SIRGAS geodetic reference frame in all countries of the Americas.

Strengthen regional cooperation to expand geodetic capabilities, in order to ensure the development, sustainability, and promotion of a global geodetic reference frame, in accordance with the United Nations Resolution “A Global Geodetic Reference Frame for Sustainable Development.”

Promote the adoption and use of the SIRGAS geodetic reference frame in all countries of the Americas.

Strengthen regional collaboration aimed at building geodetic capabilities, with the purpose of ensuring the development, sustainability, and dissemination of a global geodetic reference frame, in accordance with the United Nations Resolution “A Global Geodetic Framework for Sustainable Development.”

Themes

Topic 1

Studies of the atmosphere and analysis of the Earth System

Geodynamic monitoring, atmospheric studies, determination of changes in mean sea level, geophysical studies based on the SIRGAS infrastructure

Topic 2

Development and maintenance of the SIRGAS reference framework

Reports from the SIRGAS Analysis Centers, review and update of processing and combination strategies, analysis and modeling of frame of reference deformations, processing of GNSS observations.

Topic 3

Applications of the SIRGAS reference framework

Practical applications aimed at the adoption of SIRGAS at the sub-regional and national levels. Reports from SIRGAS member countries, progress in SIRGAS adoption, use and availability of SIRGAS products

Topic 4

Modeling of the Earth’s gravity field

Geoid, gravimetry and international height reference system. Advances and activities necessary to support the development of the unified vertical reference system, modeling of the Earth’s gravity field and absolute gravity in the SIRGAS countries.

This edition of the SIRGAS 2024 Symposium has been organized jointly with the

and has had the support of

While the SIRGAS Symposia are primarily attended by National Representatives, Working Group members, and project members, these events are open to the entire regional and international geodetic community, and we cordially invite you to:

Regional organizations linked to the publication of geospatial information and Earth observations

Public and private agencies that use geodetic and geophysical information

National institutions responsible for defining geodetic reference frames

Universities and research centers in fields related to geodesy and geophysics

Scientists, professionals, technicians, and students whose activities and research are related to the objectives of SIRGAS
