Abstract:

This article introduces a method to determine of the zero-height geopotential value W0lc and difference between local Geoid and global Geoid EGM 2008 at the zero - height level. The global geopotential Wo of the EGM2008 with GPS/leveling data of the local vertical networks of Vietnam is used to estimate W0lc and difference between their surfaces. The computation used some different error models for more accuracy of the obtained results. The optimal results were achieved as W0lc = 62636847, 465 m2/s2; δζ = 0, 865m.
