SIRGAS-CON is a science-driven network of continuously operating GNSS reference stations, covering the Americas and the Caribbean with precisely known coordinates in the International Terrestrial Reference Frame (ITRF). With more than 50 organizations involved, all contributions to SIRGAS-CON are voluntary. The reliability and long-term stability of the network are ensured by redundancy and extensive guidelines guaranteeing the quality of the GNSS measurements, the data processing and the resulting station coordinates. Based on SIRGAS-CON and the SIRGAS operational infrastructure, SIRGAS provides the following products:

SIRGAS-CON loosely constrained weekly solutions
