According to the SIRGAS Bylaws, each four years the SIRGAS Directing Council elects new SIRGAS president and vicepresident, who also appoint chairs for the SIRGAS working groups to conform the SIRGAS Executive Committee. The members of the SIRGAS Executive Committee for the period 2015 - 2019 are:
President: William Alberto Martínez Díaz, Departamento Administrativo Nacional de Estadística, Bogotá - Colombia
Vicepresident: María Virginia Mackern Oberti, Universidad Nacional de Cuyo, Universidad Juan Agustín Maza, Mendoza, Argentina
Chair of the WGI (Reference System): Víctor Cioce, La Universidad del Zulia, Maracaibo, Venezuela
Chair of the WGII (SIRGAS at National Level): Roberto Pérez Rodino, Universidad de la República, Uruguay
Chair of the WGIII (Datum vertical): Sílvio Rogério Correia de Freitas, Universidade Federal do Parana, Curitiba, Brazil.
On July 23 the Argentinean - German Geodetic Observatory (AGGO) was formally opened, thus completing the first stage of a project jointly addressed by the National Council of Scientific and Technical Research of Argentina (CONICET by its Spanish acronym) and the Federal Agency for Cartography and Geodesy of Germany (BKG by its German acronym). In this way, the Transportable Integrated Geodetic Observatory (TIGO), which operated successfully for over ten years in the Chilean city of Concepcion, reopened with the name of AGGO, near the Argentinean city of La Plata. AGGO is a fundamental geodetic observatory where the GNSS, VLBI and SLR techniques, atomic time system, very high precision gravimetry system and a variety of environmental sensors are operated in collocation. Internationally, AGGO data will be used by the scientific services of the International Association of Geodesy (IAG) and the International Astronomical Union. Regionally, it will contribute to the improvement of the SIRGAS realisation and leverage the Joint Action Plan to Expedite the Development of the Americas' Spatial Data Infrastructure, signed in 2012 by the Pan American Institute of Geography and History (PAIGH), SIRGAS, the GeoSur Programme and UN-GGIM Americas. AGGO is also a tangible response to the Resolution on the Global Geodetic Reference Framework for Sustainable Development, issue by the United Nations General Assembly on February 26, 2015.

The 26th of February, 2015, the General Assembly of the United Nations adopted its first Resolution on the Global Geodetic Reference Frame for Sustainable Development. With this Resolution, it is recognized the importance of a globally–coordinated approach to Geodesy: the science focused on accurately measuring the shape, rotation and gravity field of planet Earth. SIRGAS, as the responsible for the reference frame in Latin America and the Caribbean, contributes to this initiative together with the International Association of Geodesy (IAG), the Pan-American Institute for Geography and History (PAIGH), the Regional Committee of the United Nations Global Geospatial Information Management for the Americas (UN-GGIM: Americas) y GeoSur.
