Physical meaning of some electrical properties data.
There are 19 different types of signals, and sample labels from 13 modes in the spacecraft flying data are presented in this study. A total of 22800 samples were acquired, where each sample contained 1000 features. More specifically, the physical meaning of the data is shown in Fig 8, combining twelve elements of the physical process: (a)Pitching attitude angle, (b)Axial load factor, (c)Roll angle, (d)Posture Quaternion(q1), (e)Posture Quaternion(q2), (f)Posture Quaternion(q0), (g)Posture Quaternion(q3), (h)Gyro angular velocity of X axis, (i)Gyro angular velocity of Y axis, (j)Gyro angular velocity of Z axis, (k) Gyro angular velocity of S axis, (k) Vector of Quaternion.
