Relative calibration methods.
| Methods | Principles | Advantages and Disadvantages | Priority |
|---|---|---|---|
| MEMS gyroscope | Angular momentum | Mature technology; | ★ |
| Fiber optic gyroscope | Sagnac effect | Low-precision and narrow-band commercial gyroscopes; | |
| Laser gyroscope | Sagnac effect | Difficult to obtain and expensive for high-precision gyroscope. | |
| Time grating sensor | ”Time–space” effect | Angle resolution: 0.02”; Accuracy of calibration system: <2”; Poor high-frequency performance: ±8.2” accuracy at 400 Hz. |
