<p>The invention relates to an accelerometer for an inertial measuring unit that reduces the cost and/or improves the safety of said inertial measuring unit. The accelerometer of the invention is an accelerometer for an inertial measuring unit of the type including a resonator having a resonance frequency that is modified by a device containing a mass capable of movement based on the accelerations applied to said mobile mass, characterised in that it is bi-axial and includes a single planar mobile masse sensitive to accelerations occurring along any axis in a plane parallel to that of the mass, the mass being associated with at least two devices for converting the force applied to an acceleration-sensitive mass into electric signals, the sensitive axes of force conversion devices being mutually arranged so that it is possible to determine their components in said plane.</p> |
