Precise Approach of Earth Gravity Field and Geoid - PAGravf4.5

🌏 Develops the unified analytical algorithm system for various modes of terrain effects on various gravity field elements outside the geoid, effectively to synthesize various heterogeneous observations for the gravity prospecting modelling and gravity field data processing.

🌏 Sets up the gravity field approach algorithm system with the spatial domain integration algorithms based on boundary value theory and spectral domain radial basis function approach algorithms to realize the all-element analytical modelling in whole Earth space from various heterogeneous observations in the different altitudes, cross-distribution and land-sea coexisting cases.

🌏 Presents the quantitative selection criteria for terrain effects according to physical geodesy, realizes the gravity prospecting modelling from heterogeneous observations, and develops some ingenious physical geodetic algorithms to improve and unify the regional height datum.

🌏 Realizes the detection of observation gross errors, measurement of external accuracy indexes, control of the computational quality and modelling performance to strengthen application capacity of Earth gravity field.
