<p>The invention concerns an apparatus for determining attitudes, in particular the body angle (υ) and the banking (ζ) of an aerodyne, comprising: a gyroscopic device with related components supplying the components of the vector (Φ) of the aerodyne instantaneous rotation; means for calculating, from the gyroscopic measurements, a matrix of attitudes (b1, b2, b3); accelerometers integrated with the gyroscopic device; and means for comparing data calculated from the gyroscopes to supply corrections to compensate the errors or drifts of the gyroscopic device. Said apparatus is characterised in that the comparison is performed between a vector Ug of vertical direction supplied by the gyroscopic device and a vector Ua of vertical direction supplied by the accelerometers.</p> |
