The article considers the structure and principle of operation of the weapon stabilization system, which is technically a set of sensors and a computer system connected to the gun drive. The stabilization system ensures the constancy of the angles between the axes of the fixed coordinate system and the axes rigidly connected to the object of stabilization. It is established that the quality of armament stabilization systems is evaluated by the following indicators, both in stabilization mode and in guidance mode: stability, accuracy of weapon stabilization, stabilization quality, guidance speed and nature of distribution on the angle of rotation of the control panel, stabilizer time, continuous operation stabilizer, reliability of operation and the nature and timing of transients when working out the angles of inconsistency. The accuracy of stabilization is the main indicator that characterizes the operation of the fire control system in stabilization mode. External disturbances caused by continuous random oscillations of the hull by mobile light armored vehicles cause deviation of the stabilized armament from the specified direction of guidance. A new piezoelectric sensitive element of the weapon stabilization system and the expediency of using the two-channel method to increase its accuracy are considered. It is established that due to the use of additionally introduced into the design of the sensitive piezoelectric element of the second measurement channel, there is no error in its output signal from the influence of vertical acceleration, from residual non-identical designs of identical piezoelectric plates and masses, from temperature, humidity and external pressure. environment (ie instrumental errors), which can be significant.
