摘　　要：从所需电池片数量、外围电子器件、所需视场角度、制造工艺等要求出发,设计了工程上适合皮卫星应用的太阳敏感器,并分析获得太阳入射角——光电流非理想的余弦特性、光电流的噪声起伏、处理电路非线性、A/D采样非线性、温度测量不确定性等因素对光电单元测角产生的误差,从而获得太阳矢量测量误差为8.12°。Conventional sun sensor cannot be used low power consumption were designed for the in the attitude determination of pico-satellite. The micro sun sensors attitude determination of pico-satellite according to the requirements of the number of photodiode, electronic device, the visual angle, manufacture process, etc. The test error of sun vector by 8.12~ was analyzed, which is caused by non-ideal cosine curve between incident angle and photocurrent, the photocurrent noise, nonlinear of analog circuit, nonlinear of A/D converter, inaccuracy temperature, etc.
