METHOD OF NAVIGATION OF AIRCRAFTS Russian patent published in 2014 - IPC G01C21/20 G01S5/02 

FIELD: radio, communication.

SUBSTANCE: method of increasing accuracy of aircraft navigation consists in multipath measurements of the integral parameters of reflected signals using radio waves emitted in the form of rays, and determining the resulting vector of angular oscillations of aircrafts, which characterizes the angular oscillations of aircrafts in roll and in pitch based on the analysis of integral parameters of the reflected signals. Analysis of the integral parameters of the reflected pulses of multipath measurements is based on comparison of the integral parameters of the reflected pulses on the lateral rays of the multipath measurements over the flat area of the area surface. The rays of the multipath measurements are located in two orthogonal planes, one of which coincides with the direction of movement of the aircraft, the other plane of the rays is perpendicular to the aircraft direction of movement. The resulting vector of angular oscillations of the aircraft in the bound coordinate system of the aircraft is determined sequentially at regular intervals to detect changes in angular oscillations in pitch and in roll of the aircraft during its movement.

EFFECT: improving accuracy of aircraft navigation by analyzing the parameters of the reflected pulses obtained by multipath measurements over the flat surface, and to determine the resulting vector of angular oscillations of aircrafts, which characterizes the total angle of deflection in pitch and in roll of aircrafts to control their movements.
