Two-Channel MEMS Gravimeter of the Automated Aircraft Gravimetric System

Introducing the principle of constructing an aviation gravimetric system with any type of gravimeter

“…In [1] and in publications [18][19][20][21][22]: digital simulation and analysis of the AGS gravimeter motion under the action of external disturbances is described in detail. That is why we shall include only the main findings based on analysis of the obtained charts and tables.…”

“…As a result of performed simulation, we obtained charts [18][19][20][21][22] -it was established that damping coefficient ξ is advisable to increase only in the case of main resonance: ω=ω 0 (ξ=0.705) and in the case: ω=2ω 0 , ω=3ω 0 , when the beating sets in (ξ=0,45). That is, it was substantiated that it is expedient to choose damping coefficient of gravimeter of 0.705.…”

“…Sensing elements are arranged so that the vertical accelerations in them act oppositely. A more detailed description of the way the two similar sensing elements are located, is available (depending on the type of gravimeter): in string [20], capacitive, dual channel MEMS capacitive [21].…”

“…The following articles examined separate types of gravimeters: gyroscopic single-channel and dual-channel gravimeters [16], piezoelectric single-channel and dual-channel gravimeters [17,18], string gravimeters [19,20], capacitive single-channel and dual-channel gravimeters [21,22].…”

“…It is implemented in the new dual-channel gravimeters: string [19], capacitive, dual-channel capacitive [21].…”
