<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 at least one mass capable of movement based on the accelerations applied to said mobile mass, characterised in that it is bi-axial and includes at least two mobile masses sensitive to accelerations occurring along any axis in a plane and each associated with a device for converting the force applied to an acceleration-sensitive mass into electric signals, the sensitive axes of the masses being mutually arranged so that it is possible to determine their components in said plane.</p> |
