[Ring laser gyro] Gyro noise has many causes, thus there are a large number of ways to specify gyro noise and model its effect. The most basic model for gyro noise is a random constant or bias. The random bias can be modeled in the same way the null-shift bias is modeled, and the two effects can be added together. Gyro noise may also be modeled as a random walk (i.e., integrated white noise).
