ORIENTATION METHOD OF INSTRUMENT MOVED IN PILOTED AIRCRAFT, AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC F41G3/00 B64G1/66 

FIELD: aviation.

SUBSTANCE: method involves determination of a position and orientation of a freely moved instrument inside an aircraft. For that purpose, commands are supplied to emit pulse ultrasonic signals (UT) with emitters distributed along the instrument. Signals are received with UT receivers at distributed points on the instrument inside the aircraft. Moments of emission and reception of signals are synchronised via a radio channel. Temperatures are measured at arrangement points of UT emitters and UT receivers. As per this data and delay times of reception of signals, the above position and orientation of the instrument is determined. As per the current position of markers, turning angles of the instrument for its guidance to the same markers are calculated, and commands are generated for the instrument rotation. A guidance system includes required means for carrying out the above operations.

EFFECT: providing guaranteed guidance of an instrument freely moved relative to the instrument inside the aircraft to markers of any type.
