The invention discloses a geosynchronous orbit space environment and effect integration detection apparatus. The apparatus comprises a tubular detector housing, two collimating layers arranged on thehousing in a covering manner, and detection elements and function layers arranged in the tubular housing, the two collimating layers comprise central openings used for receiving incident space environment particles, metal layers and insulating layers are alternately arranged in the tubular detector housing, wherein the internal space of each insulating layer is used for containing a dosage sensingelement, a single-particle overturning detection element and an internal charging potential monitoring sheet, and the surfaces of the two collimating barrier layers are respectively provided with other detection elements. The apparatus is advantaged by simple structure, various functions, light weight, and low power consumption.
