Abstract:

The influence of the altimetry errors on the marine geopotential recovery was studied. And the formulae for the altimetry stochastic errors transmission during the marine gravity anomalies prediction were presented. In the end, the predicted geopotential errors with seveal resolutions from 8 cm altimetry random error were simulated. The paper proposes some references for the Chinese altimetry satellite design in the future.

Key words: altimetry, inverse Vening-Meinesz formula, stochastic error, marine geopotential, gravity anomalies prediction.
