Analysis of the surfaces and gravitational fields of planets using robust modeling methods

摘要

The work focuses on the development of methods and algorithms for the simulation of celestial bodies' dynamic and static states. There are 2 types of models: global and local ones. The creation of local simulation models (LSM) is complicated as the emergent properties of the system are getting lost. Nevertheless, LSM are of great importance when analyzing planetology processes. When areas are covered with reference points unevenly and the distance between them increases, the method used in the work provides the higher accuracy of model forecasting compared to the use of interpolation formulas. LSM allow investigating both the whole planetary system and its local parts and are aimed at the predictive determination of topographic, gravimetric, and magnetic parameters.
