FEATURES OF GRAVIMETERS IN MODERN GRAVIMETRIC SYSTEMS

The paper reviews modern gravimeters of aviation gravimetric systems, their design and principle operation. Their advantages disadvantages, features functioning processing the received data are analyzed. It is shown that high-precision measurements gravitational acceleration (g) extremely relevant necessary for many fields science technology. main characteristics known given. has been established have insufficient accuracy (2-10 mGal). Under action g, armature moves down inside magnetic circuit causes a change in electromagnetic flux. an external flow obstacle, this will induce two EMF obstacles sections, which included series-opposite. total effect these errors on output signal gravimeter-invention be zero. mutual connection sections provides cancellation due to influence flows, can significant when installing gravimeter such moving object as airplane. In same way, device works under obstacle vertical aircraft, cancelled TG. TG, residual instrumental cancelled, since they opposite signs measuring channels secondary winding, connected oppositely. new TG significantly greater than effects fields, errors. substantiated
