| Abstract: | The self-consistency problem of the point mass model method for approximating the Earth's external gravity field is discussed.Considering the fact that the disturbing gravity cannot be obtained through direct measurement at altitudes above the Earth's surface,a solution which made for studying the approximation accuracy of the point mass model method is proposed.That a test of internal and external consistency accuracy based on the ground and airborne gravity observations of Australia was made.Numerical res... |
