| Abstract: | The basic principle of least squares collocation in frequency domain and its application in the field of the downward continuation on satellite gravity gradiometry data are researched deeply in the paper. Comparing to general least squares collocation in space domain. the method is of high effective and stability. Furthermore, it can be considered as effective tools for processing large amounts of gravimetric data, and provides an alternative for refining the local gravity field from satellite gravity gradiometry data. |
