FIELD: observation of mass traveling along circular path and creating gravitational interaction. SUBSTANCE: technique involves determination of intensity gradient of gravitational field created by traveling mass with the aid of gravitational device located in center of circular path on observing line that crosses path of travel of mass. Simultaneously time reading is conducted, time interval between two moments at which intensity gradient assumes one and same value is isolated. Time interval during which optical device also located on observing line registers information on passage of traveling mass through observing line is fixed by eclipse of source of light radiation. Then propagation speed of gravitational interaction of bodies is computed with due account of propagation speed of light in medium. EFFECT: improved reliability of technique. 1 cl, 6 dwg
