Aircraft integrated information processing subsystem and spaceflight measurement and control system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of aerospace measurement and control, in particular to an aircraft comprehensive information processing subsystem and an aerospace measurement and control system. Background technique [0002] The development of aerospace measurement and control system has roughly gone through three stages: the first stage is the era of ground-based measurement and control, mainly before the 1970s, which marked the completion of the development of the measurement system of measurement and control stations. Successfully developed a unified carrier measurement equipment (such as a unified S-band measurement and control system) for long-range missile systems and multi-service service capabilities, realizing the integration of multi-service transmission and orbit measurement and control. The second stage is the era of space-based measurement and control. Mainly from the 1980s to the 1990s, the high-precision satellite navigation...

Problems solved by technology

[0003] At present, with the continuous development of combat modes, the flying missiles in the aircraft need to distinguish between high and low trajectories. The high trajectory is the leader missile, and the others are combat missiles; , the network will be difficult to restore; at the same time, due to the single communication method of the existing aircraft, the measurement and control of the aircraft has the defects of easy interruption and incomplete data acquisition
