FAQ

Q1: How does bias instability affect long-term navigation accuracy?

Engineering: Bias instability (≤0.03°/h) causes cumulative errors over time. Commercial: In industrial automation, 0.03°/h drift over 100 hours leads to ≤3° positioning error, critical for conveyor alignment.

Q2: What’s the difference between ARW and bias instability?
Engineering: ARW (≤0.003°/√h) is short-term random noise; bias is long-term zero offset. Commercial: ARW ensures smooth arm movements, while bias prevents drift in factory-line tracking systems over shifts.

Q3: How does temperature impact zero offset drift?
A:Engineering: Thermal drift (≤0.02°/h/°C) is corrected via -40°C~+85°C calibration. Commercial: In outdoor weather stations, temperature swings from -40°C to +85°C maintain ≤0.02°/h drift, ensuring accurate tilt measurements.
