Construction principles, structure and results of experimental studies of the laser gyrocompas based on Zeeman ring laser are discussed. It is shown that the application of four-frequency mode and sensitivity axis reverse significantly improves the accuracy of azimuth determination. The independent constituents of gyrocompas errors are considered.
