Model XB120/F50 High Accury Single-axis Fiber Optic Gyroscope With 0.5 °/hr Bias Drift
F50 type fiber optic gyroscope is a uniaxial low precision military
grade fiber optic gyroscope produced by Institute of
Photoelectric Technology, Beijing University of Aeronautics and
Astronautics.
Main performance indicators
| Bias Drift at full temperature range from －40℃ till 60℃ | ＜0.5°/hr(1σ ) | 2H continuous test,10s smooth result |
| Bias Drift Repeatability at full temperature range from －40℃ till 60℃ | ＜0.5°/hr(1σ ) | Calculation results of six test data |
| Random Walk | ＜0.05°/√hr | |
| Scale Factor Non-linearity at full temperature range from －40℃ till 60℃ | ＜200ppm(1σ ) | |
| Scale Factor Repeatability at full temperature range from －40℃ till 60℃ | ＜200ppm( 1σ) | Calculation results of three test data |
| Range of measured angular rate | ±500°/s | It can be adjusted according to need |
| Bandwidth | ≥200Hz | The internal closed-loop bandwidth is larger than 2K,and the updata
rate of output data determines the bandwidth of gyroscope |
| Operating temperature | －40℃ ~60℃ | |
| Storage temperature | －50℃ ~70℃ | |
| Vibration | 4.2g,20Hz~1000Hz | Sweep-frequency Vibration without Resonance |
