AUTONOMOUS SYSTEM TO FLY AIRCRAFT OVER SPECIFIED TRAJECTORIES Russian patent published in 1998 - IPC

FIELD: radio navigation. SUBSTANCE: invention is intended for control over aircraft of agricultural aviation conducting aviation-chemical operations. Proposed system includes meter of Doppler frequencies with three-beam antenna system, meter of angle of pitch, course meter, multiplexer, analog-to-digital converter, subtracter, digital-to-analog converter, control desk and indicator. Computation of projection of center of masses on certain direction and subsequent calculation of deviation of value of center of masses of aircraft from specified trajectory are carried out in compliance with measured values of Doppler frequencies, angles of pitch and course angles. This provides for high-accuracy approach of aircraft to preset point with performance of standard turn and for rectilinearity and equidistance of flight trajectory of aircraft thanks to continuous indication of deviation of aircraft from specified trajectory. EFFECT: increased functional reliability of system. 3 dwg
