FIELD: instrument engineering.
SUBSTANCE: invention relates to instrument making and measurement equipment. Essence of the invention is that the method of compensating for the effect of the slow meander on the readings of the laser gyroscope comprises the steps at which the laser gyroscope is subjected to climatic tests and the coefficients of the n-th power of the dependence of the coefficient A(T)Mode01 are determined from temperature at certain mode, current value of slow meander amplitude SM=A(T)Mode01⋅Scur is determined, where Scur – current value of amplitude of frequency support, which is measured at each cycle of operation of three-axis laser gyroscope, determining current drift indicators Tdsqx,y,z and magnetic drift Mdsqx,y,z and determining the rotation angle value per cycle of operation of the laser gyroscope in radians Ωx,y,z=Kqx,y,z·(Rasn+SM)-(Tdsqx,y,z+Mdsqx,y,z), where Kqx,y,z is scaling coefficient of laser gyroscope, Rasn is output characteristic of laser gyroscope.
EFFECT: high accuracy of compensating errors in measurement results.
