Solution to the problem of joint evaluation of the nonstationary model of GSP drift and the state vector of a navigation system

Abstract

The solution to the problem of evaluation in real time of nonstationary coefficients of the polynomial model of drift of a gyro-stabilized platform (GSP) is considered. In order to solve this problem, the estimating equations for the state vector of the navigation system (NS) are derived taking into account correlations between the equations of the object and the observer. Evaluation of the coefficients of the model of the GSP drift is realized based on minimization of nonlinear probabilistic criteria.
