Satellite dynamics environment is a test that must be undergone by a wave-front corrector used for space optical system and random vibration environment is an important factor among them.

波前校正器应用于空间光学系统必然要经历卫星动力学环境，随机振动环境是其中一个很重要的影响因素。

Furthermore, an algorithm that can create the random Angle error directly is devised without considering the satellite observation platform error.

此外在不考虑卫星观测平台误差的情况下，还设计了直接产生随机测角误差的算法。
