The Spherical Harmonic Model of Gravity Field in Mainland China by Slepian Local Spectrum Method
Acta Geodaetica et Cartographica Sinica
For the purpose of calculating the gravity field model through spherical harmonic method only based on local measurements, it calculated that the measured gravity field data in mainland China by Slepian local spectrum method, and also it evaluated that the error effected by the non-uniformity of measured points by the known spherical harmonic model of GOCE satellite datasets. Firstly it calculated that the Slepian basis functions in mainland China and took the 72 order spherical harmonic modeldoi:10.11947/j.agcs.2017.20150542 doaj:3745515bebd548cd80f8bdf4b4d95a87 fatcat:lgqhwiwdafab7ifcey3rwgu6py
