Fiber Optic Gyroscope (FOG) IMU accuracy
is primarily influenced by temperature-induced drift, vibration-induced noise, and mechanical misalignment (non-orthogonality). Key custom factors include the, fiber length/coil configuration, calibration quality (bias/scale factor), and environmental sealing, which directly affect long-term stability and navigation performance.
Key factors impacting FOG IMU accuracy include:
- Environmental Temperature Sensitivity: FOGs are sensitive to thermal gradients, which can cause significant bias drift, requiring precise compensation or stable, low-thermal-gradient, thermal-controlled packaging.
