RADIO RADIATOR POSITION FINDING METHOD Russian patent published in 1997 - IPC

FIELD: radio navigation; study of ionosphere parameters. SUBSTANCE: after measuring the angles of arrival of ionosphere radio wave in horizontal and vertical planes, as well as parameters of ionosphere by means of vertical sounding and trajectory calculation of coordinates of point of reflection, median characteristics of ionosphere are determined above radio direction finder point and in area of reflection of radio signal by forecast, increments of parameters of ionosphere along radio wave propagation route are determined, parameters of ionosphere in area of reflection of wave are determined more accurately taking into account data of vertical sounding and forecast, longitudinal and transversal inclinations of ionosphere reflecting layer are calculated and measured azimuth and angle of elevation are corrected. EFFECT: enhanced accuracy of position finding due to simulation of increments of ionosphere parameters along trajectory of radio wave propagation. 1 dwg
