FIELD: instrument making.;SUBSTANCE: invention relates to the field of instrument making of platform-free inertial navigation systems (PFINS) and platform-free inertial orientation systems (PFIOS) on the basis of laser gyroscopes (LG) based on triaxial LG (TLG) with one common vibrator (CV). Calibration of zero shifts of TLG with the CV is carried out not directly by TLG readings - increments of integrals of absolute angular speed vector projections on the axis of TLG sensitivity, but by resulting error of spatial orientation determination by means of the platform-free inertial orientation system on the basis of triaxial laser gyroscopes with one common vibrator.;EFFECT: improved accuracy of calibration.;2 cl
