The measurement process of the attitude Angle based on single trailing earthhorizonsensor is investigated, and an analytical formula of attitude compensating error is obtained.
基于单轨迹地平仪研究了地平仪测量姿态角的过程，得到了解析形式的姿态角误差补偿公式。

The first part is to analyze the two error sources of the earthhorizonsensor: one is earth oblateness and the other is non-uniformly distributed atmospheric infrared radiation.
