FIELD: instrument making.
SUBSTANCE: invention relates to gyroscopic instrument making, and is intended to determine scaling factors of the three laser gyroscopes (TLG) with mutually orthogonal sensitivity axes during calibration (certification) of strap down inertial navigation systems built on the basis of TLG, or their component parts. Method of determining scaling factors of triaxial laser gyroscope consists in, that the laser gyroscope is installed on faceplate of the rotary table, sensitivity axis of laser gyroscope is oriented collinearly to the faceplate rotational axis, then successively in two opposite directions the faceplate is turned through to the preset angle, wherein from the gyroscope output a number and a sign of information pulses are recorded, then the scaling factor is measured as a relation of double value of the specified rotation angle to the difference between the number of information pulses, recorded during rotation of the faceplate contraclockwise and in clockwise order, wherein the orientation of sensitivity axes of triaxial laser gyroscope is collinearly to the axis of the faceplate rotation two other sensitivity axis put orthogonally to the axis of the faceplate rotation.
EFFECT: accuracy increase of determining TLG scaling factors.
