MODE OF PREPARATION OF INITIAL DATA OF RANGE-DIFFERENCE NAVIGATIONAL TASK

摘要

FIELD: the invention refers to the field of radio technique and may be used in range-difference systems of definition of the position of the sources of radio emissions.;SUBSTANCE: the mode is based on measuring of two differences of distances Δr₁₂ and Δr₁₃ to two pairs of mobile supporting points {O₁,O₂}and {O₁,O_{3 , }} the coordinates ,j= 1,2,3 supporting points O_j in the moment of time of measuring of distances, then the vector of measured values is transformed into the vector of the coordinates of the three points F₁,F₂ and M belonging to a hyperbolina: the vector is stored and transmitted along the channels of transmitting information into the center of processing information for using it in quality of initial data at solution a range-difference navigational task; at that the points F₁ and F₂ defines the focuses of the hyperbolina if it is a hyperbola or an ellipse or a focus and its projection on a directrix if it is a parabola and the third point belongs to the hyperbolina in such a manner that the position of its project on the direct F₁F₂ defines the form of the curve of the second order.;EFFECT: decreases volume of stored and transmitted data.;5 dwg
