Problems solved by technology

This electronic system architecture mainly includes time-division multiplexed data bus, standard onboard computer, standard development language and standard external unit RTU. In order to realize various functions of the subsystem, each subsystem needs to have its own controller, Sensors and actuators, which will easily lead to the extreme complexity of the entire system, will also lead to a large number of unnecessary repetitive equipment in the system, and the resource utilization rate will be reduced. Moreover, once the design is qualitative, the functions completed by the satellite cannot be changed on-orbit. There are defects such as single function, inability to adapt to the changing needs of users, and low user experience

Abstract

The invention provides a satellite electronic system architecture suitable for on-orbit dynamic configuration. A satellite electronic system is divided into six areas: an integrated management controlarea, which is responsible for the most basic management and control function of a satellite; an interface driving area, which is formed by a sensor access module and a driver module of an executionmechanism; a data storage area, which is formed by a bulk memory having file management capability and is responsible for data storage; a data processing area, which is formed by a plurality of same-configuration high-performance processor modules, wherein each processor module can load and remove application waveforms as needed, thereby realizing dynamic configuration of its function; and a radiofrequency comprehensive area and an optical frequency comprehensive area, which are connected with a microwave antenna array and an optical antenna array respectively. The provided satellite electronic system architecture suitable for on-orbit dynamic configuration can be suitable for change in application scenarios and on-orbit dynamic function change, thereby realizing a one-satellite multi-purpose effect, and improving satellite resource utilization rate.

Description

technical field [0001] The invention belongs to the technical field of spacecraft, and in particular relates to a satellite electronic system framework adapted to dynamic configuration on orbit. Background technique [0002] The technology of the spaceborne data management system has been widely applied to the satellites that have been launched, and a unified standard has been formed for the spaceborne data management system in my country. The spacecraft data management system is mainly composed of a central processing unit (CTU, Central Terminal Unit), a remote control unit, a telemetry unit, and several remote units (RTU, Remote Terminal Unit) and other equipment and software. These devices are connected to each other through the serial data bus, and jointly complete the functions of data transmission, processing, storage and management on the spacecraft. Large-scale spacecraft, such as the data management subsystem of a manned spacecraft, and the data management subsyste...
