Is there a high-precision MEMS solution to replace fiber optic gyroscope (FOG)？

In scenarios that require high-precision inertial navigation, high-performance MEMS inertial sensors have been able to partially replace fiber optic gyroscopes (FOGs) in recent years, but whether it can be completely replaced depends on specific application requirements. For example, the MEMS IMU U6488 produced by Micro-Magic Inc., the bias instability of the gyroscope can reach 0.2°/h, and the accuracy of Zero bias stability (1 σ, 10s) can reach 1°/h; Random walk reaches 0.03 º/√hr; This product can replace low precision fiber optic gyroscopes to meet short-term high dynamic tasks (less than 30 minutes), or in GNSS assisted scenarios, the position error of combined navigation (such as RTK + high-precision MEMS) can be less than 1 meter.
