The laser gyro has no moving parts and there is no mass imbalance problem, so it is not sensitive to the vibration and impact acceleration of the carrier, and the sensitivity to gravity acceleration is negligible. Therefore, the unbalance compensation system is not needed, and the output signal has no cross-coupling term. High precision, offset value less than 0.001 degrees per hour, random drift less than 0.001 degrees per hour, long-term precision stability, no change in output within 9 years, excellent repeatability.
There are no precision parts for the laser gyro. The variety and quantity of parts that make up the gyro are small, the machining is less, and it is easy to mass-produce and automate production. The cost is about one-third of that of the conventional gyro.
