METHOD OF AIRCRAFT NAVIGATION Russian patent published in 2012 - IPC G01C23/00 G01S5/02 

FIELD: instrument making.

SUBSTANCE: invention may be used to build various radiolocating or similar systems designed for navigation of aircrafts (AC) by detection of location and control of AC movement. A reference area map is used, which has been made prior to start of AC movement, a measured section of the reference map area is selected, the current map is made - parameters are measured on the measured section of the reference map with the help of radio waves emitted in the form of beams. At the same time produced values of current and reference maps of the measured section are compared, indices of data proximity are calculated, errors of measurements are identified on the basis of assessment of an error of AC angular oscillations measurement by pitch, confirmed values of a correction signal by planned coordinates and altitude are detected, AC movement control is carried out on the basis of correction of their location as the appropriate measured section is travelled through.

EFFECT: improved accuracy.
