Abstract


A new automated piezoelectric gravimeter of aviation gravimetric system (AGS), which has higher accuracy (1 mGal) and speed (fully automated) than known to date, is considered in this article. The principle of work of the piezoelectric gravimeter which based on the physical phenomenon of direct piezoelectric effect is described and its mathematical model is derived. It is established that by choosing the design parameters of the piezoelectric sensing element of piezoelectric gravimeter can set its own frequency of 0.1 rad / s and avoid the need for a low-pass filter in automated AGS
