Integrated solution to the problem of estimation and identification of a state vector of the gimballess navigation system of a reentry spacecraft

Abstract

An approach to the synthesis of autonomous navigation support is considered for a spacecraft executing an arbitrary spatial maneuver under conditions of internal and external disturbances. The proposed approach ensures the solution to the problem of a joint estimation of the state vector of a navigation system and the identification of the parameters of sensitive elements. A complex observer ensuring the autonomous estimation of the parameters of angular and linear motions is used to improve the accuracy of the estimation of the parameters of angular and linear motions.
