High-precision piezoelectric gravimeter of automated aviation gravimetric system for measurements of anomalies of gravity acceleration
Journal Title: Геофизический журнал - Year 2015, Vol 37, Issue 4
Abstract
A new piezoelectric gravimeter of automated 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 based on the physical phenomenon of direct piezoelectric effect is described and its mathematical model is derived. It has been established that by choosing the design parameters of the piezoelectric sensing element of piezoelectric gravimeter we can set its own frequency of 0.1 rad/s and avoid the need for a low-pass filter in automated AGS. The prospects for further improving the accuracy of a new piezoelectric gravimeter are analyzed.
