MODE OF MEASURING EARTH'S GRAVITATIONAL FIELD Russian patent published in 2005 - IPC

FIELD: gravimetry, may be used for measuring of gravitational field of the Earth and of other planets' which have on its orbits cosmic apparatus with gravitational-magnetic system of orientation and stabilization.

SUBSTANCE: the essence of the invention is in measuring of stabilizing fluctuations of the cosmic apparatus along channels of rolling, pitching and yawing and then using these measurements to pick out: angles of static deviations (γ_ct, θ_ct, ψ_ct) by decomposition of measured fluctuations into Fourier's series; disturbing moments,(M_x, M_y, M_z), corresponding to static angles of deviations (γ_ct, θ_ct, ψ_ct) and gravitational parameter is defined on cited formula. At repeated flight of the cosmic apparatus over this region of the Earth magnetic stabilization system is switched off, frequency fluctuations of the cosmic apparatus in each stabilization channel are measured, and gravitational parameter( on the basis of measuring of quick-changeable parameters) is defined on cited formula. Received meanings of gravitational parameter are defined on the basis of static parameters and on the basis of fluctuated characteristics are compared and regions of anomalies of the gravitational field of the planet are picked out, constructive parameters of the cosmic apparatus are changed and measures are repeated.

EFFECT: simplifying and reducing of prices of the mode and expanding spheres of its application.
