AUTOMATED GEAR TO MODEL ANOMALIES OF GRAVITATIONAL FORCE Russian patent published in 1999 - IPC

FIELD: sea navigation. SUBSTANCE: invention is intended for practical sea gravimetric measurements directly related to change of gravitational force and caused by sluggishness of sea gravimeters and to dynamic errors related to oscillating motions of ship. Proposed automated gear includes immobile base with two rising columns between which rotary frame is mounted for azimuthal movement and is connected to driving mechanism with the help of micrometric screw that is connected via testing potentiometer to recorder. EFFECT: enhanced precision of modeling of anomalies of gravitational force, expanded amplitudes and forms of modeled anomalies, improved detailing of research, increased accuracy and reliability of gravimetric operations. 2 dwg
