This work aims the implementation, in the State of Minas Gerais, of a GPS network. After the construction of the benchmarks, professionals of the Department of Geodesy of IBGE, in different sections to collect data, occupy them. Then, these data were processed by the scientific program OMNI and adjusted by the program ADJUST. The organization and the selection of data to process, testing different strategies, were described: the consideration or not of the co-variances between different observed vectors, the influence of the transformation of the vectors from ITRF97 to the WGS84 and the elimination of outliers, in the calculated coordinates; besides of the evaluation of the quality of the coordinates of know stations that were used as control. The final coordinates of each station of the Geodesic Network of the State of Minas Gerais were calculated, emphasizing that is a responsibility of the IBGE the choice of the method that it consider most adequate and the publication of the official values of these coordinates. We hope to have been contributed to this.
