Coordinates of the SIRGAS-CON reference stations

The following coordinates are generated within the routine processing of the SIRGAS-CON network:

Loosely constrained weekly solutions in SINEX format (or normal equations) for later computations, i.e. combination within the IGS polyhedron, determination of multi-year solutions, etc.

Weekly station positions aligned to the same reference frame applied by the IGS (International GNSS Service) to generate the final GNSS satellite orbits. These coordinates serve as reference values for surveying in Latin America.

Multi-year solutions (coordinates + velocities) for those applications requiring time depending positioning.

The SIRGAS-CON coordinates are available at This server is maintained and managed by the IGS Regional Network Associate Analysis Centre for SIRGAS (IGS RNAAC SIRGAS).
