Abstract
The technological development of the last years has produced revolutionary changes in the way of positioning, in the Reference Geodetic Systems and in its materialization in geodesic networks. Prior to the emergence of global satellite navigation systems, the positions of points on the surface of the earth were considered as fixed over time, but today it is possible to determine their evolution given the hight achievable accuracy. This has brougnt us to the birth of a new type of geodetic networks, the networks of permanent stations. Over the years there have been several Geodetic Reference Systems that have existed in Spain officially and the features of the associated geodesic networks that have materialized them.
