|Obliquity sensor, just as its name implies is Angle size and transmission Angle perception. If it is only measuring Angle? The answer is more than that. When an object has a tilt, we can use Newton's laws of basic mechanics, through the analysis of the concrete stress distribution of the object, get the acceleration of the object, the integral in time be able to get speed, acceleration and speed in time for integral can get displacement. Through the obliquity sensor, therefore, we can get is acceleration, velocity and position information.
