1. A method for measuring the earth's gravitational field anomalies (GPP) and other planets for laboratory work based on the use of a spacecraft (KA), framed flywheel orientation and stabilization system, located on a circular orbit, measuring its coordinates and the angles determining the oscillation stabilization KA characterized in that the spacecraft at a certain analysis interval T, the monitoring portion comprising GPP through flywheel orientation and stabilization system is introduced in a self-oscillating mode with the following parameters: ! amplitude KA φ0 = 45 °, corresponding to self-oscillation detection maximum impact of the GEA, including its anomalies in the dynamics of the spacecraft! phase oscillations v0 = 0, defined by the condition of the initial combination of its own satellites and forced vibrations,! self-oscillation frequency ωp! ! wherein Jx, Jy, Jz - the moments of inertia about respective axes KA; ! - gravitational parameter - the value of the gravitational parameter; ! μ = 398 602 km3 / s2 - Earth's gravitational constant; ! RKA = R3 + h - the radius of the spacecraft orbit! where rg - Earth radius (spherical shape rg = 6371 km); ! H - height of the circular orbit satellites; ! K1, K2 - the coefficients of the law of formation of control moment orientation and stabilization system at a channel pitch! and, based on a comparison of the differences stabilization oscillation amplitudes: ! where θi * - the actual values ​​of the AC oscillation stabilization in pitch channel on analysis interval T i-th time instants; ! θ0 ij - modeling values ​​obtained by solving the equation of motion of the model with different values ​​of j-mi gravitational parameter ω2 0j; ! i = 1, 2, ...
