Некоторые аспекты разработки и использования стационарных фильтров в навигационных системах

Abstract

The paper considers synthesis of stationary filters, i.e., the filters with constant gain matrix. These filters are shown to be unable to provide high quality of data process- ing over the total time interval up to the steady-state mode. SF optimization at t → ∞ degrades the processing quality in the initial period; when reduced, this error causes the growth of steady-state error. We propose a number of criteria for select- ing SF gain factors. The required processing quality is reached by using two-stage filters.
