In 2011, Italy established a new geodetic reference system, the European Terrestrial Reference System 1989 (ETRS89), which was based upon the ETRF2000 reference frame at epoch 2008.0. In order to maintain this reference, the IGMI defined a permanent

On this study the theoretical and practical approach of an optimal geodetic reference frame realization is described in detail. The Hellenic area due to its strong geodynamic behavior creates a rather inhomogeneous velocity field. This issue plays a

The accuracy and stability requirements for the International Terrestrial Reference Frame (ITRF) postulated by the Global Geodetic Observing System (GGOS) are not met so far. The GGOS–SIM project builds a software tool that by simulating the space

In July 2003 the International Association of Geodesy (IAG) established the Global Geodetic Observing System (GGOS). The GGOS is integrating the three basic components: geometry, the earth rotation and gravity. The backbone of this integration is the

The assessment of the accuracy and the stability of the global Terrestrial Reference Frames (TRFs) is a matter of great importance for the geodetic community. The classical Helmert transformation plays a crucial role in terms of evaluating the datum

Geospatial data gained from different sources have to be referenced to the same geodetic datum and coordinate system. Forming of joint reference system enables easier update and geometric harmonization, access, exchange and use of geospatial data. Ho

The classical geodetic reference systems suffer in many cases from severe inconsistencies, mainly due to the fact that they were realised by old type observations. By the use of GNSS, these distortions could be identified implementing a 3D similarity

Local geodetic datums have been developed in the past, in order to satisfy the surveying and mapping requirements of countries all over the world. The broad use of GPS observations, as part of the surveying routine, has shifted the interest from the
