DEVICE FOR DETERMINATION OF ANGULAR ORIENTATION Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: digital device of azimuthal orientation has two nonreversible blade propellers with vertical rotation axis passing through point of suspension of device which directions of rotation are mutually antithetic, signal processing unit including pulse formers, unit of referencing of pulse signals, reversible counters, code inverters, switches, clock pulse generator, pulse signal dividers, adder, indication register, decoder, two similar measurement channels which sensitive elements are installed in horizontal plane so that axes of rotation of these two pairs of nonreversible blade propellers in it were mutually perpendicular. Axes of one of these pairs are parallel to axial section of object. Device has microprocessor computing corrections of azimuth caused by roll and trim of device, accomplishment register manufactured in the form of indicator, for instance. EFFECT: improved authenticity of orientation of mobile objects. 10 dwg
