| Abstract: | The basic equations for the solution of global point-mass model based on the complex combination and complete tensor components of global gravity gradient were studied and established in this paper,from which point-mass harmonic analysis solutions of single determined and over determined boundary value problems based on satellite gravity gradient were attained.The stability of point-mass harmonic analysis solutions was obtained via the decomposition of large linear equations using blocked cyclic matrices.Fi... |
