Zusammenfassung:According to the astronavigation circuit board and the assembling method of the plurality of detectors of the astronavigation circuit board, the detectors are fixed on the metal structure, so that the heat transfer problem of the detectors is solved, the temperature change rate of the detectors is reduced, and the photoelectric conversion linearity, the service life and the electromagnetic compatibility of the detectors in the use temperature range are improved; by designing the optical fiber wiring groove, the wiring path is standardized, the problems of cross interference and operation damage of optical fibers and electronic components are avoided, and the optical fiber wiring reliability is improved; through the mode that the detector is independently fixed and the detector lead is flexibly connected with the circuit board, the design and assembly difficulty of the circuit board when the detector is directly welded on the circuit board is reduced, and the design efficiency is improved; and the assembling r
