This publication is the fifth of a series of articles devoted to the description of technology of determination the parameters of a gravitational field of Earth on gradiometric measurements. This article presents the computation algorithm of observation equation coefficients and the formulas for transformation these coefficients from LNOF to GRF. For the optimal gravity harmonic coefficients computation it is need to make «observation minus computation» and the observation equation coefficients filtering. Then presents technology of parameters gravity field estimation by least square method. Using the matrix of observation equation coefficients and the differences: the measured components of tenzor gravity minus the computed components of tenzor gravity, we can determine of the parameters of Earth gravity field.
