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 critical role in stable and longterm
geodetic datum. The methodology of the Minimization of the Kinetic Energy Criterion
(MKEC) is defined and analyzed on a permanent GNSS network consisting of 151 stations. The
sites velocities values were estimated from seven years continuously data. The application
formula shows that the kinematic energy is minimized more than 60 percent in two different
approaches for the International Terrestrial Reference Frame and the European Terrestrial
Reference System 1998 (ETRS89). In addition, the realization of the ETRS89 approach in Greece
is not offering any significant advantage. However, we proposed a new strategy, which minimizes
the total kinetic energy and it is found effective in local areas with strong geodynamic activity like
the Greece case.

Dimitrios Ampatzidis

Dr. Dimitrios Ampatzidis was born in Drama at 1983. He finished from 1st Lyceum of Drama at 2001. He studied at the School of Rural and Surveying Engineer at the Aristotle University of Thessaloniki (2001-2006) and graduated with a score of 7.84/10.0 (ranked in the highest 10% graduating students of 2006). He received scholarship from National Scholarship Foundation (IKY) for 2004-05 (the highest rank among all other students of the School).

On October of 2006 he entered the Postgraduate program "Modern Geodetic Application" at the Department of Geodesy and Surveying (School of Rural and Surveying Engineer). He received his Master with "Honors" (score: 9.00/10.0). On January of 2008 he was nominated as PhD candidate of the same Department. On June of 2011 he defended his PhD thesis: "Study for the optimal Geodetic Reference System realization in the Hellenic Area" in front of the Examination Committee ('Honors").
