摘要：

A geometrical and an analytical model of Reference System correction are presented and connected by means of a simple least squares method. The correction induced by the analytical method is compared with that obtained directly through the geometrical method which was previously tested in the FK5 system. The geometrical method determines the relative orientation of the FK5 with respect the dynamical reference frame given by the Planetary Theory, while the analytical method is more suitable to correct the error depending on the zone.
