Abstract: Practical problems of on-line continuous and discrete filtering (estimation of state and parameters) of the Earth pole motion by linear and linearized filters are considered. Instrumental algorithms and software tools in MATLAB are discussed. Test examples and computer experiments based on astronometric measurements are presented.

Keywords: astronometric measurements; instrumental algorithms; software tools; information model; linear and linearized filters; generalized Kalman filters; on-line filtering; Kalman-Bucy filters; Pugachev filters; fluctuations of the Earth pole.
