What is gyro random walk?

The parameter "random walk" is used throughout the fiber optic gyro community as a measure of the instruments "wideband" noise. Some- times we use this parameter to compare the performance of different types of inertial rate instruments, e.g. Dry-Tuned-Gyro (DTG), Ring-Laser- Gyro (RLG) and Fiber Optic Gyros.

What is rate random walk?

Rate random walk – Characterized by power spectral density that falls off as 1/frequency² and represents bias fluctuations caused in the long term primarily due to temperature effects. A low rate random walk is important for long-term dead reckoning performance.

What do rate gyros detect?

A system of three rate gyros, each oriented to one of three mutually perpendicular axes—roll, pitch, and yaw—can control a missile or aircraft by detecting angular rates and then generating proportional corrective signals.

What is gyro angular rate?

Gyro sensors, also known as angular rate sensors or angular velocity sensors, are devices that sense angular velocity. Angular velocity. In simple terms, angular velocity is the change in rotational angle per unit of time. Angular velocity is generally expressed in deg/s (degrees per second).
