FIELD: navigation.
SUBSTANCE: invention relates to methods of strapdown inertial navigation of small-sized moving objects. N sensitive elements are installed on a mechanical base in the form of a cube, each of which contains n sensors of physical quantity. Sensitivity axes of sensors located on the side faces of the cube are oriented at an angle α to the surface of the lower face of the cube. Output signals of sensors are converted into projections of signals on axes of orthogonal coordinate system Xo, Yo, Zo with scaling factor K0=(Cos(90–α)=Sinα. Xo, Yo axes are oriented along the diagonals of the upper face of the cube, and the Zo axis is perpendicular to the centre of this face. Obtained signals are summed up and navigation parameters of the object movement are calculated.
EFFECT: high accuracy of determining navigation parameters of an object.
