Abstract: An acceleration-measuring sensor assembly includes an accelerometer subassembly with three measurement axes, mounted in a housing equipped with securing elements, and configured to determine an acceleration along a principal axis A, the assembly comprising: a single-axis principal accelerometer with a seismic mass moving in a straight line along a principal axis A, measuring acceleration along the principal axis A which is misaligned with respect to a reference axis Y by at most 50 mrad, a secondary accelerometer having at least two measurement axes and measuring respectively along two axes X and Z which with the reference axis Y form a direct orthonormal trihedron (O, X, Y, Z), the measurement precision of the two-axis accelerometer along each of its axes being at least ten times inferior to the measurement precision of the single-axis accelerometer, and an electronic processing unit configured to calculate a compensated acceleration S.
