A deterministic approach used for solving the problem of positioning and angular orientation defining of onboard direction-finder antenna based on the results of radio direction finding of radio reference points

The paper considers the possibilities and conditions for the unambiguous determination of the coordinates and angular orientation of the onboard direction - finder antenna placed on a moving object, based on the results of the azimuth-elevation radio direction finding of radio reference points. The coordinates of a moving object are determined by taken at one or several receiving points on board of a moving object measurements of radio signal delay time emitted simultaneously by at least three radio reference points. The unambiguous angular orientation in space is determined by measuring the 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 onboard DF antenna, a general approach used for solving the problem of azimuth-elevation radio direction finding of three radio reference points, methods for determining the distance to radio reference points based on the results of their azimuth-elevation radio direction finding, and the analysis of the research results.
