The invention discloses an earth-moon space ultra-large time delay inter-satellite link measurement method based on a Beidou navigation system, and the method comprises the steps: calculating the time slot pulse advanced adjustment amount of a sending moment relative to a Beidou satellite through an earth-moon aircraft, adjusting the phase of a transmitting code, and transmitting a signal at a set transmitting time slot; the Beidou navigation satellite predicts the arrival time reproduction code phase of the signal based on a Beidou satellite receiving TOA forecasting algorithm, receives the signal and calculates a one-way ranging value; the Beidou navigation satellite transmits a signal, and the earth-moon aircraft predicts the arrival time of the signal based on a TOA prediction algorithm received by the earth-moon aircraft, reproduces a code phase and calculates a one-way distance measurement value; and calculating the distance of the inter-satellite link according to the one-way distance measurement value
