Abstract:

The expected error in the computation of geoid undulations using Stokes equation due to neglected distant zones is analyzed considering the removal of lower-degree harmonics from limited gravity anomaly data and from Stokes kernel. Evaluation of the derived error equations assuming Kaulas rule for anomaly degree variances indicates that if the lower-degree components of geoid undulation are assumed known, removal of an equivalent number of such harmonics from the anomaly data alone produces the least-expected error for cap radii of less than 60 deg.
