Momentum fluctuation of the photoelectronic tracking system is one of the key problems that have effect on tracking accuracy. 摘要光电跟踪系统的力拒波动是影响其跟踪精度的一个关键问题。
The paper describes attitude of a rigid body utilizing quaternion parameter and solves the attitude control problem of a optic-electronic observatory tracking system. 本文也就光电跟踪系统的特点，采用四元数参数描述刚体姿态，解决了光电跟踪系统中的姿态控制问题。
