Aerospace Instrument-Making Annotation << Back FUNCTIONAL MODELING OF THE SPATIAL ORIENTATION METHODSIN THE SYSTEMS OF SATELLITE NAVIGATION FOR MOBILE OBJECTS O.V. Drozd, N.S. Kolobanova, D.V. Kapulin The functional model of the navigation receiver developed in the MATLAB/Simulink realizing an interferometric algorithm of determination of orientation angles of a mobile object. The functional model allows studying and correcting the parameters of spatial orientation methods, analyzing the infl uence of the troposphere environment of the navigation signal on the accuracy of determining the coordinates of the object and so on. The proposed functional model simulates the characteristics of the digital signal processing unit of the navigation receiver and is intended for use in the preliminary design stages and testing of navigation equipment in order to shorten their duration and reduce the cost of prototyping. Key words: angle measuring of navigation equipment, spatial orientation, GNSS-receiver, functional modeling. Contacts: E-mail: olvldrozd@gmail.com Pp. 26-35.
