HELICOPTER GRAVIMETRIC COMPLEX Russian patent published in 1999 - IPC

FIELD: gravimetric measurements in shelf zone of world-wide ocean and in water areas of enclosed ponds at depths from 0 to 120 m, in almost inaccessible areas, in marsh-ridden and forest-covered areas. SUBSTANCE: complex includes two gravimeters in submarine armor, two instruments determining absolute altitudes put on support in the form of platform with increased weight placed on external mount of helicopter, device determining altitude of hovering of helicopter, desks controlling gravimeters, instruments determining absolute altitudes, device determining altitude of hovering of helicopter, navigation system, airborne gyro-stabilized gravimeter with control desk and airborne computer. In this case outputs of gravimeters and instruments determining absolute altitudes are connected to inputs of desks controlling these instruments and to computer. EFFECT: increased accuracy, efficiency and informativity of measurement of field of gravitational force when searching for and evaluating deposits of hydrocarbons in shelf zone, in water areas of enclosed ponds, in almost inaccessible mountain, forest- covered and marsh-ridden areas. 1 dwg
