The invention relates to a multi-parameter autonomous diagnosis and identification method suitable for satellite illumination conditions, and belongs to the field of on-orbit satellite illumination condition diagnosis and identification. The method comprises the following steps: 1, acquiring a measurement signal of a logic sun sensor, sun included angle data, a measurement signal of an analog sunsensor and an output current of a solar cell array; 2, judging whether the output of the measurement signal of the logic sun sensor is TRUE or FALSE; 3, judging whether the output of the solar included angle data is TRUE or FALSE; 4, judging whether the output of the measurement signal of the analog sun sensor is TRUE or FALSE; 5, judging whether the output of the output current of the solar cellarray is TRUE or FALSE; 6, establishing a logic tree; and 7, judging whether the satellite is in an illumination area or not. According to the method, high-reliability illumination area-earth shadow area state detection can be realized according to the condition of on-orbit satellite telemetry parameter setting, and meanwhile, the method is simple to operate and high in applicability.
