Just as the radiosonde record has deficiencies, however, the satellite data also suffer from, among other things, limited vertical resolution, orbit drift, satellite platform changes, instrument drift, complications with calibration procedures, and the introduction of biases through modifications of processing algorithms. Other upper-air measurements have come from moving platforms such as aircraft. Observations from some high-mountain locations have also been considered part of the upper-air measurement system.  1, record 1, English, - upper%2Dair%20measurement

Tout comme les séries de données de radiosondage, les séries de données de satellite présentent des défauts découlant de différents facteurs[ :] résolution verticale limitée, dérive d'orbite, modifications de la plate-forme satellitaire, dérive des instruments, complications engendrées par les procédures d'étalonnage et erreurs systématiques découlant des modifications apportées aux algorithmes de traitement. Des mesures en altitude peuvent aussi être obtenues à partir d'autres plates-formes mobiles, tels les aéronefs. On estime que les observations réalisées en certains lieux situés en haute montagne font également partie du système de mesure en altitude.  1, record 1, French, - mesure%20en%20altitude

The attitude of a satellite is its position in space-its orientation... To stabilize a satellite, the satellite must have a system that keeps it moving evenly through its orbit. Satellites often use a spinning or gyroscopic motion to keep them stable.  4, record 2, English, - gyroscopic%20motion

A gyroscope will not only resist being moved out of its vertical position, it will also generate force as it attempts to travel in large, circular patterns. These patterns are most easily seen with a spinning top. As the top begins losing its energy, it never simply spirals straight down in the same direction that it was originally spinning. As it destabilizes, it will always begin slowly rotating or precessing in a slow, even circle that is in the opposite direction to its normal spinning motion. These circular patterns are known as "precessional" motions, and they are another aspect of a gyroscope’s movement that will occur either in air or in a vacuum and can be used to overcome gravity.  3, record 2, English, - gyroscopic%20motion

Les protons ont une charge électrique positive, que l'on peut considérer grossièrement comme mise en mouvement par le mouvement gyroscopique (ou spin) de cette particule.  2, record 2, French, - mouvement%20gyroscopique
