摘　　要：针对模拟式太阳敏感器测量精度难以满足高精度姿态测量需求的问题,提出一种准直角特性影响补偿方法。在分析模拟式太阳敏感器主要测量误差源的基础上,构建了考虑入射光线准直角特性的测量误差模型,归纳准直角误差与光线入射方向之间的关系,从测量原理入手推导误差补偿算法,对准直角特性引入的误差影响进行精准补偿。仿真结果表明,所提算法对主要误差的补偿效果显著,在太阳敏感器的视场范围内平均测量精度由补偿前的0.0599°提高至补偿后的0.0094°,大幅提高了模拟式太阳敏感器的测量精度。To address the challenge of analog sun sensors measurement accuracy in meeting the requirements for high-precision attitude measurement,a method for compensating the collimated angle effects is proposed.Based on the analysis of the main sources of measurement errors in analog sun sensors,a measurement error model considering the characteristics of incident light collimated angle is constructed.The relationship between collimated angle errors and the direction of incident light is summarized.Starting from the measurement principle,an error compensation algorithm is derived to accurately compensate for the errors introduced by collimated angle characteristics.The simulation results demonstrate that the compensation algorithm exhibits good adaptability to the main errors.Within the field of the view of sun sensor,the average measurement precision accuracy is improved from 0.0599°before compensation to 0.0094°after compensation,significantly enhancing the measurement precision of the analog sun sensor.
