SIRGAS-WGI (Reference system) was established in 1993 along with the SIRGAS project. It is responsible for coordinating all the tasks needed to implement and maintain the SIRGAS reference frame. Initially, it coordinated the GPS campaigns for the establishment of the first two SIRGAS realizations SIRGAS95 and SIRGAS2000. At present, it takes care of the adequate functioning and analysis of the SIRGAS Continuously Operating Network. Since 2005, SIRGAS-WGI promotes the installation of analysis centres for SIRGAS under the responsibility of Latin American institutions and the use of SIRGAS observations for atmospheric (ionosphere and troposphere) studies. As a result of these activities, at present, the following Analysis Centres are routinely operating:
- One Analysis Centre for the Neutral Atmosphere: CIMA (Argentina);
- Eight SIRGAS Local Processing Centres under the responsibility of Latin American Institutions: CEPGE (Ecuador), IBGE (Brazil), IGAC (Colombia), IGM-Cl (Chile), IGN-Ar (Argentina), INEGI (Mexico), IGM-Uy (Uruguay) and USC (Chile);
- Two SIRGAS Combination Centres: IBGE (Brazil) and IGS RNAAC SIRGAS (DGFI-TUM, Germany).
Beyond the coordination of the interaction between the Operational Centres, the National Data Centres, and the SIRGAS Analysis Centres (Processing and Combination Centres), the SIRGAS-WGI continues promoting the establishment of new processing centres hosted by Latin American organizations. The main objective is that, in a near future, each SIRGAS member country become capable to process the data of its own continuously operating GNSS stations following the IGS standards.
