SIRGAS products

SIRGAS-CON is a science-driven network of continuously operating GNSS reference stations, covering Latin America and with precisely known coordinates in the International Terrestrial Reference Frame (ITRF). With more than 50 Latin American 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:

Weekly station positions

Station positions and velocities (multi-year solutions)

Continuous velocity model VEMOS (Velocity Model for SIRGAS)

Tropospheric delays

Regional ionospheric maps
