FACTOR AXES [4 records]

Record 1 2006-03-13

English

Subject field(s)
  • Flight Instruments and Equipment (Aeroindustry)
  • Aircraft Piloting and Navigation
  • Navigation Instruments
OBS

Angular amplitudes and rates, and linear accelerations were measured with a six-axis-gyroscope. High-frequency vibrations were characterized with a triaxial accelerometer. Additional measurements from an onboard gyroscope with better resolution were used as a correlation factor between the two gyroscope systems. Fourier analysis of angular amplitudes and linear accelerations determined relevant frequencies for the system. Sources of error for the gyroscope system such as temperature drift and axes misalignment were identified and characterized.

Domaine(s)
  • Instruments et équipement de bord (Constructions aéronautiques)
  • Pilotage et navigation aérienne
  • Instruments de navigation
CONT

Les gyroscopes sont soumis à des dérives qui conduisent à un mésalignement des axes plateforme par rapport aux axes absolus. Les accéléromètres présentent des erreurs de linéarité de seuil, de biais qui augmentent les erreurs de la centrale [inertielle].

OBS

Le terme «mésalignement» n'est pas encore répertorié dans les dictionnaires courants. Cependant nos recherches sur Internet nous démontrent que ce terme est largement utilisé notamment dans les domaines techniques et scientifiques. Son attestation au dictionnaire ne saurait tardé, d'autant plus que le terme est parfaitement conforme aux règles du français.

Subject field(s)
  • Psychometry and Psychotechnology
  • Statistical Methods
CONT

The eigenvectors give the factor axes, and by choosing two axes, we can represent the individual values and the variables.... The factor axes are determined to give the best possible rendering of the dispersion of the data present in the matrix. The first two give the most information for graphical representation, but you can choose any axes.
