METHOD OF DETERMINING COORDINATES OF AN AIRCRAFT IN A SATELLITE-PSEUDO-SATELLITES MULTI-POSITION SURVEILLANCE SYSTEM

摘要

FIELD: radio equipment.;SUBSTANCE: invention relates to radio engineering and can be used in airspace monitoring systems to determine aircraft coordinates (AC) using AC navigation signals of global navigation satellite system (GNSS) and pseudo-satellite signals (PS) for illumination. In the method of determining coordinates of an aircraft in a satellite-pseudo-satellite multi-position surveillance system comprising N satellites with coordinates x_j, y_j, z_j, j = 1, 2 …, N, M pseudo-satellite with coordinates x_j, y_j, z_j, j = N+1, N+2 …, N+M, and receiver with coordinates x_P, y_P, z_P, in radio visibility zone of which there is an aircraft with the desired coordinates x, y, z, aircraft coordinates are determined based on measurements on scattered signals of distances R_j along propagation path "j-th navigation satellite, pseudosatellite – aircraft –receiver" using direct solution of system of corresponding non-linear equations for calculation of coordinates.;EFFECT: high accuracy of determining coordinates of an aircraft in a satellite-pseudo-satellites multi-position surveillance system.;1 cl, 1 dwg
