METHOD FOR GRAVIMETRIC SURVEY OF WATER AREA AND APPARATUS THEREFOR Russian patent published in 2016 - IPC G01V11/00 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and may be used to study the gravity field in the World ocean for the purposes of navigational and hydrographic support of the navy and the national economy. The invention includes ship navigation by planned courses, the start and the end of each course is shorted to hydrographic control point, or two hydrographic control points: the start of each course - on one point, and the end of each course - on another point, additionally measured on a moving ship at the points along the survey course, in conjunction with the measurement of gravity acceleration g_izmi water depth Z_izmi and determine the geodetic rectangular coordinates x_i and y_i and the true value of gravity acceleration g_icti. Furthermore, an apparatus for implementing the method of the water area gravimetric survey contains a sensing system, a control unit and a recorder, it is provided with depth gauge, navigation system and a calculator, wherein the input of the calculator through the control unit is connected to the outputs of the sensing system, the measured depth of the water area, navigation system, and the output is connected to the input of the recorder.

EFFECT: technical result is improved accuracy of the water area gravimetric survey.
