The system for digital control of laser gyroscope mechanical dither making use for its operation of ring laser primary signals has been developed and tested. The digital control system of the mechanical dither of the laser gyroscope includes: a two-stage amplifier, a bipolar adjustable power source and a DAC. Tests of the developed system showed that it provides the regulation of the oscillation amplitude of a ring laser in the range from 1 to 3 arc minutes and its noise according to the normal law in the range from 10 to 30 %. The aim of the work is to construct a digital system to control laser gyro mechanical dither using only primary signals of ring laser as the source of information
Key words: laser gyroscope, mechanical dither, ring helium-neon laser, Sagnac phase, FPGA, inertial sensor.
