Research on Swing Scanning Infrared Earth Sensor with Orbit Altitude Concerned

  • Online:2012-06-25 Published:2013-03-17

摘要: 本文考察了摆动式红外地球敏感器测量的工作原理,在介绍敏感器两种数学模型—圆盘模型和三维模型的基础上,增加卫星轨道高度参数为变量,讨论了在不同轨道高度下,敏感器数学模型的变化.利用小角度条件下的一阶近似处理,对敏感器模型所关心的弦宽与姿态角转换关系给出了解答.通过进行带有高度参数的修正,把敏感器的圆盘模型和三维模型推广到了其他轨道高度下.

Abstract: The model of swingscanning infrared earth sensor (SSIRES) at different orbit altitudes is researched in this paper. By reviewing the swingscanning Process of infrared earth sensor(IRES),two models, as disk model and 3D model are introduced by taking orbit altitude as a variable. The transformation from the earth chord length to attitude angles is established approximately in the condition of spacecraft closing to zero position, so that the models are extended to all kinds of orbits through calibration for interested orbit altitudes .

Key words: infrared earth sensor, orbit altitude, swingscanning, model research
