(.):  Theoretical analysis and experimental study of the ring laser gyroscope functioning under vibration influences was carried out in this work. The purpose ofthe study is to improve the technical, economic and operational characteristics, which consist in reducing the dithered ring laser gyroscope to external mechanical influences. The work provides a review of the key characteristics, design and technological solutions for constructing the most common models of ring laser gyroscopes and inertial navigation systems. Dynamic calculations of the device design have been carried out. The mechanical system functioning of the ring laser gyroscope under vibration influences was studied using finite element analysis methods. The external mechanical influence of the dithered ring laser gyroscope on output signal was studied experimentally. It is shown that errors in measuring angular velocity arise in the frequency range of the structures own resonances. Agreement between the results of calculating the intrinsic resonances of an often dithered ring laser gyroscope and experimental data has been obtained. This research will allow us to develop a methodology for designing the dithered ring laser gyroscope structure and life support systems based on the study of errors arising from external mechanical influences.
