Katerīna Morozova, Riga Technical University, Latvia
The main objective of the Doctoral Thesis is to develop a new solution for the Earth gravity field determination based on spherical-cap-harmonic modelling, using both vertical deflection and gravimetric hybrid data. The values of vertical deflections caused by gravity field anomaly are computed using digital zenith camera. It is a new kind of astrogeodetic instrument employing recent advancements in several areas of technology. The intention is to use vertical deflections along with GNSS/levelling and gravity data to improve the local quasi-geoid model including both physical and geometrical data.
