METHOD OF DETERMINING OBJECT'S OWN LOCATION IN SPACE Russian patent published in 2024 - IPC G01C21/04 G01S1/08 G01S5/14 G01R29/08 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, namely to passive radio monitoring systems, and can be used in navigation object own location control systems as an alternative method for determining coordinates, in particular, in conditions of malfunction or failure of a receiver of signals of global navigation satellite systems (GLONASS, GPS, etc.). Disclosed method is based on determining the proper location of a navigation object in space by receiving radio signals from N ≥ 2 independent radio-emitting objects with known coordinates using a triorthogonal dipole antenna system (TODAS) installed on a navigation object, measuring triplets of orthogonal components E_x,n(t1), E_y,n(t1), E_z,n(t1) and E_x,n(t2), E_y,n(t2), E_z,n(t2) using it at time t1 and t2, vectors of electric field strength E_n(t1) and E_n(t2) of received signals from independent radio-emitting objects with known coordinates, where n = 1...N is number of radio-emitting object, measurement of orientation angles TODAS in space, determination of orientation of electric field intensity vectors E_{n t}(t1) and E_{n t}(t2) in topocentric Cartesian coordinate system (CCS) OXYZ taking into account measured orientation angles TODAS ξ_α, ξ_β, ξ_γ, as well as orthogonal components E_x,n(t1), E_y,n(t1), E_z,n(t1) and E_x,n(t2), E_y,n(t2), E_z,n(t2), formation of auxiliary Ω_n(t1) and Ω_n(t2), so that they are perpendicular to vectors E_n t(t1) and E_n t(t2) and pass through corresponding radio-emitting objects with known coordinates, determining line of location of object l_n, at intersections of these planes and calculation of coordinates of own location of navigation object as point of intersection of lines of location of object l_n.

EFFECT: wider field of application of the navigation system with high accuracy of determining the proper location of the navigation object by providing polarization matching between the receiving antenna system and the field of the incoming electromagnetic wave from radio-emitting objects with known coordinates.
