Abstract Since the development of GNSS techniques, determination a precise quasi-geoid model has become even more actual. In terms this project staff Institute Geodesy and Geoinformatics (GGI) developed new based on DFHRS (Digital Finite-element Height Reference Surface) approach additionally using astrogeodetic measurements – vertical deflections (VD), which can be observed by Digital zenith c...

Abstract Since the last decade, Indonesia has continuously improved accuracy of national geoid model by conducting rapid gravity acquisition using airborne and terrestrial gravimetry. As data have been collected thoroughly in all regions, time come to carry out Indonesia’s modeling. We started our study employing Stokes Second Helmert’s condensation method Yogyakarta, Indonesia, with a target a...

Recent studies on the influence of the anomalous gravity field in GNSS/INS applications have shown that neglecting the impact of the deflection of vertical in aerial surveys induces horizontal and vertical errors in the measurement of an object that is part of the observed scene; these errors can vary from a few tens of centimetres to over one meter. The works reported in the literature refer t...

We evaluate the new regional quasigeoid model (OTG12) for New Zealand using the method which utilises the discretised integralequation approach for computing the near-zone contribution. The far-zone contribution is computed by modi ed spherical harmonics of the geopotential. Adopting the remove-compute-restore computation scheme, the nearand far-zone contributions are computed for the residual ...

A new method for dynamic measurement of deflections of the vertical (DOV) is proposed in this paper. The integration of an inertial navigation system (INS) and global navigation satellite system (GNSS) is constructed to measure the body's attitude with respect to the astronomical coordinates. Simultaneously, the attitude with respect to the geodetic coordinates is initially measured by a star s...
