Abstract

The invention discloses a satellite integrated electronic system architecture based on a universal on-board application subsystem. The satellite integrated electronic system architecture comprises a platform subsystem, a data transmission subsystem, a load subsystem and the on-board application subsystem. The on-board application subsystem comprises a storage unit, a computing unit, a network unit, a universal operating system, a system management application and other applications; the platform subsystem, the data transmission subsystem, the load subsystem and the on-board application subsystem are connected with one another through a management bus and a data bus; tasks in the platform subsystem, the data transmission subsystem and the load subsystem are divided into real-time tasks andnon-real-time tasks, the real-time tasks are completed in the corresponding subsystems, and the non-real-time tasks are sent to the on-board application subsystem through a data bus to be completed. According to the satellite integrated electronic system architecture based on the universal on-board application subsystem, the cost of an on-board data processing system and the development difficultyof an application program can be effectively reduced, and the response speed and the resource utilization rate are improved.

Description

technical field [0001] The invention relates to the technical field of satellite data processing, in particular to a satellite integrated electronic system architecture based on a general-purpose on-board application subsystem. Background technique [0002] On-orbit data processing on the satellite can greatly reduce the amount of data transmitted between the satellite and the ground, which is conducive to improving the utilization rate of bandwidth resources between the satellite and the ground. In addition, since the data is directly processed on the satellite, the real-time performance of satellite services can be effectively improved. With the continuous improvement of on-board data processing capabilities, it is of great significance to design satellite system architecture around on-board data processing methods to improve the operational efficiency and data processing capabilities of the entire satellite. [0003] According to the data processing method on the satelli...
