[0020] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown, a management method for redundant inertial measurement data includes: obtaining multi-channel IMU data collected by multiple IMU units; generating detection data by performing multi-dimensional fault assessment on the multi-channel IMU data; extracting the detection data The optimal IMU data contained in the data; the IMU unit corresponding to the optimal IMU data is used as the first IMU unit to be applied at the next moment, and the second IMU unit corresponding to the IMU data applied at the current moment is the same as the When the first IMU unit is different, the IMU data applied at the current moment is gradually corrected to coincide with the IMU data collected by the first IMU un...
