Embodiment Construction

[0049] The technical scheme of a data processor system for high-speed aircraft space-based measurement and control of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0050] The data processor is used to complete the baseband signal processing and data processing process of "aircraft-satellite-ground system" and "ground system-satellite-aircraft" two-way data transmission; the data processor collects its own status information in real time and transmits it to the external telemetry system. During the flight test, data analysis and troubleshooting can be carried out according to the state information; at the same time, the data processor transmits the forward link status such as signal-to-noise ratio and frequency deviation Doppler value to the ground system through the return link, and can monitor the forward link status. The working status and signal quality of the link.

[0051] The internal structure of the data proces...

Abstract

A data processor system for space-based measurement and control of high-speed aircraft, including: a power supply module, an interface module, a control module, an encryption module, a forward processing module, and a reverse processing module; the power supply module provides secondary power for other modules; the control The module receives control commands and sends them to other modules; the encryption module encrypts and decrypts the return data flow and the forward data flow respectively; the forward processing module receives the intermediate frequency signal, completes the receiving and processing link, and recovers the forward information, which is output by the interface module To external equipment; the return processing module receives image data, flight status information and telemetry information, and after completing the transmission processing link, generates an intermediate frequency signal and outputs it to the external radio frequency front end, and finally transmits it to the ground system; the present invention supports highly dynamic aircraft measurement and control of the carrier. It has a large coverage area; it supports multi-users and can conduct real-time two-way communication with the aircraft; it has certain interference capabilities.

Description

technical field [0001] The invention relates to a data processor system for space-based measurement and control of high-speed aircraft, which is mainly used for data processing of carriers such as satellite relay communication and high-altitude or low-altitude flying high-speed aircraft. Background technique [0002] Aircraft measurement and control refers to the measurement and control process of tracking, speed measurement, distance measurement, telemetry and remote control of the aircraft, generally including the measurement and control system on the aircraft and the ground measurement and control system. At present, traditional measurement and control methods such as direct measurement and control or aircraft relay measurement and control are mostly used in my country for aircraft measurement and control. Straight-through measurement and control means that the ground system and aircraft directly communicate wirelessly within the range of sight; aircraft relay measurement...
