Bias Stability vs. Bias Instability: Bias Stability vs. Bias Instability
Bias Stability is often the first specification engineers look at when selecting a gyro or IMU, but it does not tell the full story. Bias Instability plays a critical role in short-term precision, stabilization performance, and small motion detection. This article explains the difference between the two parameters, how each affects system behavior, and why modern high-performance MEMS solutions – including those developed by Gladiator Technologies – are engineered to optimize both short-term stability and long-term accuracy.
