In the last 30 years, Geodesy has evolved by leaps and bounds, influenced by the knowledge that satellite geodesy has mainly contributed. In a review of the last 30 years we identified a paradigm shift in “positioning”. A new expression “Georeferencing” has emerged and has been installed in society. For coordinate users, it required a phase of adaptation and accelerated training. The technology of Satellite Positioning Systems was imposed in the 90's, not having the necessary basic infrastructure, nor with trained human resources for its efficient use.
Standing at this moment in time, the year 2021, we remember and try to write that past story, that transition stage that it was necessary to experience. We have tried to leave a legacy in honor of those who preceded us and necessary for the knowledge of coordinate users to come.
This contribution presents a specific view of what was the evolution of the geodetic infrastructure, focused on the Argentine Republic and its participation in the continental and international context. Accompanying this history, they have tried to expose the human resources training processes that allowed specialists to update themselves to face the planning, survey and calculation tasks that the new satellite positioning technologies demand.
