Analysis of systematic effects in the national vertical reference system of the Czech Republic

Popis výsledku v původním jazyce

The paper focuses on systematic effects present in a national implementation of the vertical reference system. The vertical reference Kronstadt-57 (Bpv) used in the Czech Republic is based on Molodensky´s normal heights. For the reconstruction of geopotential numbers normal field of Helmert´s spheroid and the respective telluroid construction should be taken into account. Moreover, the geopotential numbers have to be transformed to the zero-tide system in order to comply with IAG standards. Still, sucha geopotential number is influenced by the gravity values incorporated in the so-called normal corrections. Besides the main source of distortion - Potsdam gravity reference - we identified other sources of errors incorporated in gravity information, including neglected technological corrections, like the height of a line of sight. The focus is on the identification of various systematic effects contained in geopotential numbers. All these effects are analysed and modelled. Finally, by t
