Abstract

The invention discloses an on-orbit reconstruction method and system for an aerospace electronic system based on FPGA. The method is based on an FPGA technology and can realize software and FPGA on-orbit reconstruction functions of the aerospace electronic system. The method plays a key role in astronavigation electronic system on-orbit fault restoration, and relieving of the influence of the universe space single event effect (SEE) on astronavigation electronic equipment such as satellites. The autonomous health management and on-orbit maintenance capabilities of the aerospace electronic system are fundamentally improved. And on-orbit autonomous configuration, self-test, autonomous repair and maintenance can be realized. Therefore, the system performance and reliability are greatly improved.

Description

technical field [0001] The invention belongs to the field of on-orbit upgrade maintenance and control, and in particular relates to an FPGA-based on-orbit reconfiguration method and system for an aerospace electronic system. Background technique [0002] As the functions of aerospace systems become more and more complex, more and more functions are implemented by FPGA, which puts forward higher requirements for system on-orbit reconstruction, on-orbit maintenance, mission upgrade and health management. With the continuous deepening and upgrading of the on-orbit application of aerospace systems, there is an urgent need for a technology that can systematically and comprehensively upgrade software and reconfigure FPGA on-orbit to achieve iterative upgrades of applications. [0003] Traditional satellites, spacecraft and other system functions are highly customized, and on-orbit maintenance is generally achieved through application software. The hardware function cannot be chan...
