При этом входное воздействие в виде линейного ускорени  должно быть иевзм пго в процессе измерени .those. To determine the value of the device zero displacement, it is necessary to have information on the output signals of the accelerometer with two distinct values from each other: and $ Ex angular velocity of the vessel rotation, as well as information on the values of these angular velocities | At the same time, the input action in the form of linear acceleration must be inevitable in the process of measurement.

Данный способ позвол ет повысить точность определени  смещени  нул  акселерометра с гидродинамическим чувствительных элементом, так как отпадабт необходимость в развороте прибора, а измерение скорости вращени  чувствительного элемента может быть выполнено с высокой точностью.This method allows to increase the accuracy of determining the zero displacement of the accelerometer with a hydrodynamic sensitive element, since there is no need to rotate the device, and the measurement of the speed of rotation of the sensitive element can be performed with high accuracy.
