Global gravity field model inversion method

The invention discloses a global gravity field model inversion method. The method comprises the following steps: step 1: acquiring low-orbit gravity satellite data, and preprocessing the low-orbit gravity satellite data; step 2: calculating a pure Earth gravitation acceleration observation value by virtue of numerical differentiation; step 3: establishing a novel observation equation according toan observation value constant weight strategy; and step 4: estimating parameters, and obtaining an Earth gravity field model position coefficient. According to the acceleration domain residual error analysis of a reference model, a symmetric Toeplitz covariance matrix is established by directly adopting an autocorrelation sequence as a basic element, a complicated operation process of a high-dimensional huge matrix can be effectively avoided when the acceleration covariance matrix is calculated by an orbit prior dense array by virtue of an error propagation law, and the time for fixing the weight can be reduced, so that the calculation efficiency of the gravity field model can be improved. Compared with a classical method, an algorithm provided by the invention is simple and efficient in operation; and moreover, the stability and reliability of the inversion calculation efficiency of the gravity field model can be ensured.
