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.

The working principle of MEMS gyroscopes can be divided into two parts: driving and detection:​ I. Driving Principle​ II. Detection Principle​ In order to improve its measurement accuracy and stability, some compensation and calibration techniques are usually adopted. I. Temperature Compensation​ II. Vibration Noise Suppression​ III. Linear Acceleration Compensation​

1. Instrument calibration: must be strictly calibrated for the FOG before use to ensure the accuracy of measurement. 2. Environment assessment: understand the temperature, pressure, humidity and other environment conditions of the oil well to ensure FOG can work normally under these conditions.

1.Measurement accuracy: according to the accuracy requirements of the oil well survey to choose.If the measurement accuracy is required, FOG with high resolution and low error should be selected. 2.Operating temperature range: the temperature conditions in the oil well may be harsh, it’s need to choose a FOG that can work stably in the range of high temperature or large temperature changes.

1.Small size: 2.Strong resistance to shock and vibration: 3.Low power consumption: 4.Easy integration and mass production: 5.Relatively high measurement accuracy: 6.Fast response speed:
