METHOD OF DETERMINING BANKING ANGLE OF BANKING AIRCRAFT

摘要

FIELD: physics.SUBSTANCE: method employs information on the Earth's magnetic field (EMF) vector measured by an EMF sensor in a coordinate system associated with a banking aircraft. The signal measured by a banking angle sensor is summed with the correction signal of said angle which is calculated based on the inclination angle of the EMF intensity vector, magnetic heading angle and pitch angle of the aircraft. The sensitivity function of the correction signal of the banking angle is determined depending on the sensitivity function of the measurement error of the banking angle of the aircraft by an EMF sensor to errors in determining the pitch and yaw angles of the aircraft, calculated based on the inclination of the EMF intensity. The pitch and heading angles of the aircraft are selected such that the sensitivity function of the correction signal of the banking angle does not exceed a value of said angle which is allowable on calculation accuracy.EFFECT: higher accuracy of determination.3 cl, 2 tbl, 8 dwg
