SIRGAS Analysis Center – IBGE
Since 2005, through the Coordination of Geodesy, IBGE has conducted the weekly processing of the data from all the stations of the Brazilian Network for Continuous Monitoring of GNSS-RBMC Systems. The purpose of this activity is to assess the quality of the GPS observations and maintain the new Geocentric Reference System SIRGAS2000, officially in use in the country since February of the same year.
