geoid

The study was aimed at developing a geoid model using Unmanned Aerial Vehicle (UAV) technology. To accomplish this, a UAV was deployed to capture imagery of the study area from a height of 150m, with a ground resolution of 4.19cm. A total of 3737 images were obtained, covering an area of 725.804 hectares. The existing ellipsoidal and orthometric heights were used to georeferenced the acquired images. For the analysis, 35 points were utilized, with 20 points designated as ground control points (GCPs) and the remaining 15 points as check points (CPs).

Function system have been constructed on the basis of multiortogonal decomposition, that give possibility to research the internal construction, figure and gravity field of the Earth.

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.
