The invention provides an on-orbit autonomous diagnosis method and system for a sailboard solar angle meter of a geostationary orbit satellite. The method comprises the following steps of S1, performing outlier elimination processing on current data measured by the sailboard solar angle meter; s2, carrying out smooth filtering processing on the current field elimination data obtained in the step 1; s3, performing sun tracking angle calculation according to the current smoothing filtering data obtained in the step 2 to obtain three groups of sun tracking angles; s4, the three sets of sun tracking angles obtained in the step 3 serve as input, the difference value between every two sun tracking angles is calculated and compared with a fault threshold value of the sun angle meter, and whether the sun angle meter breaks down or not is judged; and S5, on-satellite autonomous calculation of the illumination condition of the satellite is carried out, and when the satellite is in a shadow period, on-satellite autonomous diagnosis of the solar angle meter is not carried out. The method can be used for autonomously diagnosing the faults of the sailboard solar angle meter during the in-orbit period of the stationary orbit satellite, timely discovering the faults of the sailboard solar angle meter, ensuring that a solar array points to the sun in real time, and ensuring the energy safety of the satellite.

    本发明提供了一种静止轨道卫星帆板太阳角计在轨自主诊断方法及系统,包括如下步骤:步骤S1:将帆板太阳角计测得的电流数据进行野值剔除处理;步骤S2:将步骤一得到的电流剔野数据进行平滑滤波处理;步骤S3:以步骤二得到的电流平滑滤波数据进行太阳跟踪角解算,得到三组太阳跟踪角;步骤S4:以步骤三得到的三组太阳跟踪角作为输入,计算两两之间差值并与太阳角计故障阈值相比较,判断太阳角计是否故障;步骤S5:星上自主计算卫星光照情况,当卫星处于阴影期时,不进行太阳角计星上自主诊断。本发明可用于静止轨道卫星在轨期间帆板太阳角计故障自主诊断,及时发现帆板太阳角计故障,保证太阳阵实时指向太阳,确保卫星能源安全。
