Problems solved by technology

[0003] However, the current traditional single modeling interpolation method has low accuracy, and often cannot take into account the physical and geometric information in the actual data, and lacks an error compensation method with strong operability and low computational complexity
And the improvement method often lies in the adjustment of parameters, which is not universally applicable, and cannot fully adapt to a wide variety of gravity field data.
