Abstract
The paper discusses the relationship between Allan variance and error variance of sensor bias estimate obtained by averaging over a certain period. Allan variance is shown to coincide with this variance in some cases. Bias estimation accuracy can be improved using nonlinear filtering methods in the conditions of uncertain error model.
