Key stages of preparation of the initial data for the construction of the sea topographic surface

Research of heights of surface of the Black sea with the use of information of satellite altimetri was done. The model of heights of the Black sea is built. Got results it was by comparison to the heights of European kvazigeoid.

 

Determination of the geoid – gravity field and topography of the Black sea according to the satellite altimetry data

Objectives. The method of satellite altimetry as a relatively new approach to precise satellite surveying, which provides the different Earth sciences by a most complete information about the state of the ocean and its changes over time. In particular this method uses in scientific researches of geodesy, oceanography and climatology. The models of ocean dynamic topography are based on the altimetry data also. Methodology.

Optimization of least squares method to determine the harmonic coefficients on the sphere

Knowledge of the gravity field takes significance place in today's world. Such information is very important for performing of a number of contemporary problems related to satellite technologies. Such problems include: the launch of launch vehicles, satellites orbit prediction, the study of the surface of the oceans, transformation of normal and geodetic heights and more.
