MODE OF DEFINITION OF CORRECTIONS TO THE DEPTHS MEASURED WITH AN ECHO-SOUNDING DEVICE Russian patent published in 2007 - IPC G01S15/00 G01V1/38 

FIELD: the invention refers to hydrography particularly to the modes and the means of definition of corrections to the depths measured with an echo-sounding device at surveying the relief of the bottom of water areas.

SUBSTANCE: the technical result is increasing accuracy of definition of corrections to the depths measured with an echo-sounding device at surveying the relief of the bottom, increasing the depth of calibration with fixed metrological characteristics. The mode of definition of corrections to the depths measured with an echo-sounding device at survey of the relief of the bottom of water areas and arrangement for its execution provide possibility of accurate measurement of a vertical gradient of the depth by hydrostatic pressure at each horizon of calibration due to synchronously measured parameter on the base with known length and definition of accurate increasing of the parameters for each horizon of calibration owing to calculation of difference of the parameters' readings following through a small interval of time as a result constant systematic errors of measurements of increasing distance to the surface of water areas or increasing hydrostatic pressure are excluded.

EFFECT: increases accuracy of definition of corrections to depths.
