METHOD FOR DETECTION OF ANGULAR ORIENTATION IN AIRCRAFTS Russian patent published in 2009 - IPC G01S5/10 

FIELD: radio engineering.

SUBSTANCE: array of aircraft condition vectors are expanded, estimate values of air speeds are defined for corresponding values of aircraft condition vector, varying estimate values of wind speed and wind direction, quality of decision made on wind parametres is assessed, results of calculations are compared with the threshold value, which defines a priori specified accuracy of wind parametres evaluation, when threshold conditions are met during the next iteration, the wind parametres are values corresponding to these conditions, and based on navigation triangle of speeds they calculate values of air speed and course angle, found parametres of wind are used in the next cycle of measurements as average values of limited sample of estimated wind parametres.

EFFECT: expansion of its application field due to more complete accounting of aircraft flight parametres under conditions of destabilising factors effect, for instance wind.
