Our dual-axis MEMS gyroscope integrates core algorithms such as full-temperature compensation, installation misalignment angle compensation, nonlinearity compensation, and zero-offset compensation. Through multi-sensor data fusion, it achieves zero-bias stability < 0.1°/hr and angle random walk < 0.01°/√h across a wide temperature range of -40°C to 85°C. Even in high-speed rail vibration environments (peak acceleration> 5g), it maintains dynamic response errors below 0.01°/s, reducing costs by over 60% compared to traditional fiber optic gyroscopes while preserving navigation-grade accuracy.
