Inertial line-of-sight stabilization technique of semi-strapdown control using mirrors

According to the characteristics of the line-of-sight kinematics in mirror stabilization platform, a general method based on the artificial mass stabilization platform was used to reconstruct LOS angle rate by utilizing the basic mirror kinematics equations. Then the relation between mirror rotation and the field-of-view was figured out. Due to the law of reflection, an auxiliary shaft must be made for mechanical mass stabilization or semi-strapdown stabilization. Analyzing this two methods deeply show that the methods are both feasible for mirror LOS stabilization control, but semi-strapdown stabilization would accord with the future needs.
