Нелінійний оцінювач кватерніонів та кутових швидкостей космічного апарату за даними вимірювань на ковзному інтервалі

Abstract

Nonlinear estimator of spacecraft attitude parameters estimation was developed in the paper. Quaternions and angular velocities, which define the position of coordinate system related to the spacecraft with respect to the orbital coordinate system, are taken as state variables. Method, based on variational principle using the measurement data on the moving horizon, is proposed.
