The paper considers the study of the possibilities and conditions for the unambiguous determination of the coordinates and angular orientation of the on-board direction finding antenna placed on a moving object, based on the results of the azimuth-elevation radio direction finding of radio-antennas. The coordinates of a moving object are determined from measurements at one or several points of reception on board of a moving object of radio signal delay times emitted by at least three radio reference points, and the unique angular orientation in space is measured by viewing angles of at least three radio reference points of at least two direction-finding pairs of receiving points with intersecting (non-collinear) bases. The article presents the mathematical features of determining the spatial position of the unit, a general approach to solving the problem with azimuth-elevation radio direction finding of three radio orientations, methods for determining the distance to radio orientations based on the results of their azi-mutual elevation radio direction finding and analysis of the research results.
