After combining the SIRGAS-CON-C core network with the densification SIRGAS-CON-D sub-networks, the following products are available:

Loosely constrained weekly station coordinates in SINEX format (or normal equations) for later computations, i.e. for the IGS polyhedron computation, multi-annual solutions, etc.

Weekly coordinates aligned to the IGS05 frame (a realization of the ITRF2005) for applications in Latin America.

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

The final SIRGAS-CON products are provided by the IGS Regional Network Associate Analysis Centre for SIRGAS (IGS-RNAAC-SIR), which at present operates at the Deutsches Geodätisches Forschungsinstitut (DGFI).
