Abstract

In order to improve the capability of on-demand customization and agile reconfiguration of space network, and to improve the scalability and reliability of space network, this paper proposed a method of spacecraft software in-orbit high-reliability maintenance method that is suitable for space network. This method is based on the electrical erasable memory of the onboard computer, uses various methods to improve the reliability, writes the reconfiguration data into the memory, and realizes the non-volatile reconfiguration of onboard software based on multiple granularities such as parameters, modules, processes or complete software. In addition, this method uses the hardware EDAC function to detect and correct errors in the memory during operation, which further improves the robustness. The in-orbit application and a large number of tests show that the method is suitable for on-demand customization of space network and can realize in-orbit reconfiguration of onboard software with high reliability.
