Momentum fluctuation of the photoelectronic tracking system is one of the key problems that have effect on tracking accuracy. 摘要光電跟蹤系統的力拒波動是影響其跟蹤精度的一個關鍵問題。
The paper describes attitude of a rigid body utilizing quaternion parameter and solves the attitude control problem of a optic-electronic observatory tracking system. 本文也就光電跟蹤系統的特點，採用四元數參數描述剛體姿態，解決了光電跟蹤系統中的姿態控制問題。
