The LOS locating system is composed of two main components  which are an inertial reference frame to provide coarse LOS locating and a 2-axis Fast Steering Mirror to remove the frame's residual error. The azimuth and elevation of LOS are both affected by the FSM two-degree-of-freedom rotation  which should be dealt with to raise the accuracy of LOS location. This paper extrapolates LOS locating algorithm of FSM by coordinate transformation  and gives corresponding deviation analysis for different LOS poiting angles. It is found that the angle deviation grows rapidly with range of FSM's travel enlarging  so the deviation must be eliminated. Through the data analysis for deviation  a non-linear compensation algorithm is proved effective to reduce the error of LOS significantly. Taking LOS changing in [-3 deg  3 deg] as an example  two analytic expressions are given  and the LOS locating accuracy rises by 34 times compared with non-linear compensation unused  and the cross coupling of LOS loating is 0.08%. 2011 IEEE.   On applying the extended intrinsic mean spin tensor to modelling the turbulence in non-inertial frames of reference 期刊论文  iSwitch采集 Science in china series g-physics mechanics & astronomy, 2008, 卷号: 51, 期号: 11, 页码: 1691-1706 作者:  Huang YuNing;  Ma HuiYang;  Xu JingLei 收藏  |  浏览/下载：35/0  |  提交时间：2019/05/10 Turbulence modelling  Non-inertial frame of reference  Extended intrinsic mean spin tensor   Extended intrinsic mean spin tensor for turbulence modelling in non-inertial frame of reference 期刊论文  iSwitch采集 Applied mathematics and mechanics-english edition, 2008, 卷号: 29, 期号: 11, 页码: 1463-1475 作者:  Huang Yu-ning;  Ma Hui-yang 收藏  |  浏览/下载：29/0  |  提交时间：2019/05/10 Turbulence modelling  Non-inertial frame of reference  Extended intrinsic mean spin tensor  Frame-dependent  Algebraic reynolds stress models  O357  5  76f60
