METHOD OF DETERMINING ACCELERATION DUE TO GRAVITY OF MOVING OBJECT AND APPARATUS FOR ITS DETERMINATION Russian patent published in 2008 - IPC G01V7/16 

FIELD: geophysics.

SUBSTANCE: according to invention, acceleration of an object α₀, is measured by a gravimeter, stationary relative to the object. The latitude ϕ, distance angle α, and velocity V_Н are determined and the results are used to calculate acceleration due to gravity g₀. The distinctive feature of the invention is that, apart from the velocity vector components V_zi, V_xi, V_yi at moments t_i и t_(i+1), the angle β between velocity vector V_Н and the plane level and the curvature radius ρ of the trajectory are determined on trajectory points. The required value of acceleration due to gravity is calculated using the formula: where ω - angular velocity of the Earth's rotation.

EFFECT: Eotvos's effect is taken into account and this increases the accuracy of determining acceleration due to gravity of a moving object without using gravimetric base stations.
