About the accuracy of calculation the main characteristics Earth's gravity field
Objective. The main purpose is to research the requirements for calculation accuracy characteristics of the Earth's gravitational field (quasigeoid heights and plumb line deflection components) based on an analysis of existing methods and requirements to determine these characteristics. Methodology. Gravimetric method is the primary method for determining the height quasigeoid and plumb line deflection components for land and shelf areas. Initial data in this case are results of the gravimetric survey.
