(geodesy)

The Deflection of the Vertical (DOV)as one basic research topic in geodesy and geophysics can characterize thedirection of gravity vector and provide one tight local tie among space geodetic techniques (Shen et al.
The authors decided to compute a gravity anomaly, geoid and deflection of the vertical for GRACE, GOCO03S and EGM2008 models using [DELTA][C.
a comparison of GRACE, GOCO and EGM2008 models to the POLREF network for a better perception of the accuracy of the used models (gravity anomaly, geoid and deflection of the vertical were computed using spherical harmonic coefficients of GRACE, GOCO and EGM2008, and the statistical characteristics were provided),
Deflection of the vertical is a term having a geodetic and gravimetric context.
FIRST RESULTS OF THE DEFLECTION OF THE VERTICAL COMPONENTS DETERMINATION
The values of the vertical on that area were confirmed by direct evaluations both components of deflection of the vertical (Banasik, 1999).
Systems for deflection of the vertical determination with such accuracy are used since 2003 at ETH Zurich and University of Hannover (Hirt and Burki, 2006).
