Abstract
Inertial unit for the measurement of accelerations and/or rotations comprising four sensors, spread out on two intersecting axes, each sensor comprising two inertial masses, each inertial mass comprising a moveable excitation part and a moveable detection part, the moveable excitation parts of a sensor being separate from those of the other sensors, said unit also comprising means for exciting the excitation parts of the sensors and means for detecting the movement of the detection parts, the two inertial masses of each sensor) being mechanically coupled, the four sensors being coupled by elastically deformable mechanical coupling means and able to transmit the excitation vibrations from one axis to the other.
