Abstract:

It is considered a new dual-channel gravimeter (DG) of the automated aviation gravimetric system (AGS), accuracy and operation speed (fully automated) above is known gravimeters. It is described the principle of the new dual-channel gravimeter, its main advantages over the known gravimeters (no signals of the errors from impact of vertical acceleration and residual nonidentity of construction of two capacitive elements in the output signal of dual-channel gravimeter). It was solved of the problem of filtering the DG output signal from high-frequency noise by setting its own rate fluctuations of 0,1 rad/s, thus avoiding the need for additional low-pass filter in the structure of AGS. Thus, the accuracy of the DG with AGS exceeds all known analogs and allows measuring the acceleration of gravity and its anomalies with an accuracy of 1 mGal.
