Abstract
An inertial measurement device comprising a housing, a plate connected to the housing via a first stage of suspension, an inertial measurement unit comprising vibrating sensors having predetermined first resonant modes of vibration and mounted on the plate via a second stage of suspension; the first stage has a resonant frequency lower than a bandwidth of the inertial measurement unit, and the second stage has a resonant frequency higher than a resonant frequency of the first stage and lower than the first resonant modes of the vibrating sensors, the first stage having four resilient suspension elements and a center of stiffness corresponding substantially to the center of gravity of the assembly formed by the plate, the second stage, and the inertial measurement unit; the second stage having one to three resilient suspension elements.
