Abstract
An accelerometer device for determining the acceleration of an object, along three axes X, Y and Z of a main orthonormal reference system and subject to a surrounding pressure, comprises a number N of accelerometer sensors of MEMS type, N at least equal to two, each sensor defined by construction in an auxiliary reference system comprising three orthonormal axes, the set of accelerometer sensors comprising at least one pair of sensors mounted to face in opposite directions and parallel to one another, and: for each of the pairs of accelerometer sensors, the sensors have components of opposite sign along two axes of the main reference system; and the axes of the reference system along which the components of the accelerometer sensors oppose the set of pairs of sensors in twos comprise at least two of the three axes X, Y and Z of the reference system, to compensate for the effect of the pressure on at least two axes of the reference system.
