ABSTRACT

Geoid determination as physical figure of the Earth and reference equipotential surface, represents one of the major tasks of geodesy, integrated in the present efforts of understanding the Earth as a system. Regionally or globally geoid determination is a problem of equal scientific and practical interest. The determination or modelling of a precise and high-resolution geoid is a subject of many research projects, the combination of different geodetic networks and observations types being of great importance on a national and on a regional level. The present paper presents a solution regarding geoid modelling, based on the astro-geodetic method and focused on the compatibility of spatial reference frames and the data integration for the proposed goal.

Keywords: geoid, astro-geodesy, astrometry, spatial reference frame.
