Since there is known the network SIRGAS-CON is the densification of ITRF in Latin America and the Caribbean. In the last years the numbers of the stations was rapidly increasing arising the need to modify the structure. During The SIRGAS 2008 General Meeting in May 2008 were conformed a principal network SIRGAS ?CON ?C and other net of densification SIRGAS?CON?D. The first is processed by DGFI (Deutsches Geodätisches Forschungsinstitut, Germany) as the IGS RNAAC SIR. And the second one, subdivided in three parts with common stations, is processed by three Local Processing Centers: IGAC (Instituto Geográfico Augustín Codazzi, Colombia), IBGE (Instituto Brasileiro de Geografia e Estádistica, Brazil), y CIMA (Instituto de Geodesia y Geodinámica, Universidad Nacional de Cuyo, Argentina). In this work they appear:  The methodology of processing adopted as CIMA, Center of processing located in the Faculty of Engineering, Universidad Nacional de Cuyo, province of Mendoza, Argentina.  The analysis of the solutions of CIMA, arisen from the comparison with other solutions sent to SIRGAS.  Finally, the first results obtained by CIMA, of the combination of solutions generated by IGAC, IBGE, CIMA and DGFI
