The embodiment of the invention discloses a calibration tool, which is characterized by comprising a main bracket, a protective cover, a box body and a connecting assembly; the main bracket comprises a first fixing frame, a second fixing frame and a vertical plate, the first fixing frame is fixed to the position, close to the upper end, of one face of the vertical plate, and the second fixing frame is fixed to the position, close to the lower end, of the other face of the vertical plate. The box body is fixed on the upper surface of the first fixing frame and is used for covering the strapdown inertial navigation assembly; the protection cover is arranged on the periphery of the first fixing frame in a sleeving mode. One end of the connecting assembly is fixed to the main bracket, the other end of the connecting assembly penetrates through the protective cover, and the connecting assembly is used for being connected with the to-be-tested ship body. The strapdown inertial navigation assembly, the Doppler log transducer and the acoustic correlation log transducer are accurately positioned, so that the positioning precision of underwater vehicle navigation is improved.
