... Gyroscopes are designed to respond only to rotation. However, all gyroscopes respond to linear motion as well, to varying degrees. While bias stability is often used as the primary figure of merit for evaluating high performance gyroscopes, many additional error sources are present in real-world applications. Especially in applications that require motion sensors, vibration and acceleration are present, and the resulting errors often overwhelm bias drift ...
