Geocentric Reference System for the Americas

SIRGAS is a non-profit organization which main objectives are focused on the definition, implementation and maintenance of a three-dimensional reference frame for the Americas, including a vertical system of physical reference. The SIRGAS initiatives are devoted to the continuous improvement of its components in order to stay at the forefront in geodetic issues and satisfy more effectively the requirements of its users.

As a member of the Commission 1 (Reference Frames) of the International Association of Geodesy —IAG— and, as a Working Group of the Commission of Cartography of the Pan American Institute of Geography and History —PAIGH—, SIRGAS provides suitable support for the development and combination of practical and scientific activities related to precise coordinates determination, navigation, geoscience research and multidisciplinary applications. The successful performance of SIRGAS as a reference and technical community is possible by the maintenance of an active social network composed by individuals and organizations working together towards achieving the objectives of the initiative.

SIRGAS advances, ongoing activities, and new challenges are discussed in the annual Symposia. This time, the Instituto Geográfico Militar of Ecuador has kindly offered to host the symposium SIRGAS2016 in the City of Quito, between 16 and 18 November. Besides the Symposium sessions, a workshop will be held on November 21-25, related to the main topics SIRGAS vertical reference system. SIRGAS

3. Real-time SIRGAS infrastructure:

Advances and activities needed to support real (and quasi-real) time SIRGAS activities.

4. Progress in the SIRGAS unified vertical reference system:

Perspectives and achievements in the implementation of the SIRGAS vertical system..

5. Practical applications related to the adoption of SIRGAS at the sub-regional and national levels:
