A conventional value for the geoid reference potential

Popis výsledku v původním jazyce

The main objective of this study is to perform a new estimation relying on the newest gravity field and sea surface models and applying standardised data and procedures. This also includes a detailed description of the processing procedure to ensure the reproducibility of the results. The following aspects are analysed in this paper: (1) sensitivity of the estimation to the Earth's gravity field model (especially omission and commission errors and time-dependent Earth's gravity field changes); (2) sensitivity of the estimation to the mean sea surface model (e.g., geographical coverage, time-dependent sea surface variations, accuracy of the mean sea surface heights); (3) dependence of the empirical estimation on the tide system; and (4) weighted computation of the value based on the input data quality. Main conclusions indicate that the satellite-only component of a static (quasi-stationary) global gravity model is sufficient for the computation of . This model should, however, be based on a combination of, at least, satellite laser ranging (SLR), GRACE and GOCE data.
