A spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. These devices are used for measuring or maintaining orientation and angular velocity.

How to measure bias instability of gyroscope with Allen deviation that has strange end behav...

I have some simulated data from a model of an IMU's gyroscopes. I am trying to use Allan deviation to verify that we have correctly modelled various sources of error in the sensor data. …

Why is the bias instability read from my Allan Deviation plot different than my simulation i... [closed]

I have simulated a gyroscope at rest with angular random walk and bias instability, following the mathworks IMU simulation model found here. In conjunction with that simulation model, I am plotting th …

How do I compute the bounds of random walk for a given ellapsed time?

I am trying to model random walk of a gyro, given some manufacturer specifications of maximum random walk in units of degrees per root-hour. My first step was to generate white noise with a standard d …
