The invention provides a multi-aircraft configuration terminal capable of being quickly accessed to a Big Dipper constellation phased-array inter-satellite link, which aims to provide a configuration terminal of small implementation technical difficulty and capable of being quickly accessed to multiple aircrafts. According to the technical scheme of the invention, an intermediate-frequency signals is sent to a dispreading unit by a signal channel unit. After the dispreading processing step, two parallel signals are respectively sent to a signal detection unit and a demodulation processing unit. The signal detection unit obtains a synchronization pulse signal consistent with a forward transmit signal of a Big Dipper II type constellation phased-array inter-satellite link in timing sequence. The demodulation processing unit outputs demodulated data and then sends the demodulated data to an information processing unit so as to distinguish a plurality of aircraft targets from each other. According to the synchronization pulse signal and the identification location information of the aircrafts, a signal generating unit generates an intermediate-frequency signal consistent with a returning reception signal of the Big Dipper II type constellation phased-array inter-satellite link in timing sequence and then sends the intermediate-frequency signal to the signal channel unit. In this way, the intermediate-frequency signal is converted into a radio frequency signal. The communication link between Big Dipper II type constellations is established.
