The embodiment of the invention discloses an aircraft integrated information processing subsystem and a spaceflight measurement and control system. The subsystem comprises a radio frequency front end module, a data processing module, an encryption / decryption module and an interface power supply module which are in communication connection. The radio frequency front end module carries out down-conversion and filtering processing on received original radio frequency carrier signals. The data processing module converts received intermediate frequency carrier signals into encryption source information and converts the encrypted to-be-sent source information into radio frequency carrier signals through baseband and up-conversion processing. The encryption / decryption module decrypts the encrypted source information to obtain decrypted source information and sends the decrypted source information to the interface power supply module. According to the subsystem and the system, through adoption of software radio and open architecture, integrated design is carried out on cooperation, visual range and beyond visual range integrated measurement and control; various wireless communication functions are realized; the integration is high; the cost is low; the expandability is high; and an aircraft can be powerfully supported to realize functions such as cooperation, visual range and beyond visual range integrated measurement and control.
