In response to IGS’s call for participation in the pilot project for the densification of the ITRF, DGFI/I is acting on behalf of the SIRGAS project as a RNAAC for South America. The analysis results of the first year of activity are presented here in terms of the internal stability of the station coordinates and the discrepancies with respect to global solutions. The r.m.s. deviations for both internal and external comparisons are in the centimeter level.
