Aerospace Instrument-Making Annotation << Back THE ACCURACY IMPROVEMENT METHOD OF ORIENTATION ANGLE AUTONOMOUS ESTIMATION USING BAROMETERS AND MAGNETOMETERS SIGNALS Т.А. Luchkina The methodical error mathematical model of orientation angle autonomous estimation by accelerometer triad and gyroscope triad signals is introduced. The method of current error compensation using barometers and magnetometers signals is discussed. The estimate of introduced method efficiency and mathematical simulation results is reduced. Keywords: gyroscopes, accelerometers, barometers, magnetometers, autonomous estimation of orientation, methodical error.
