The invention provides a spacecraft ground environment test system based on optical fiber sensing. The spacecraft ground environment test system comprises a control unit, a demodulation unit and a sensing unit. The sensing unit is fixed on a spacecraft; the sensing unit comprises a plurality of FBG sensors; the sensing unit is in signal connection with the demodulation unit through a first data transmission line; the demodulation unit is in signal connection with the control unit through a second data transmission line; the control unit is configured to send a test instruction signal to the demodulation unit; the demodulation unit is configured to receive the test instruction signal, sample the information collected by the sensing unit to obtain a spectral signal, convert the spectral signal into an electric signal and send the electric signal to the control unit through a second data transmission line; and the control unit is further configured to perform data processing on the received electric signals and perform classified storage and display on the original data and the processed data according to preset conditions. According to the invention, multi-parameter integrated testing can be realized, and the testing system is simple in process.
