Abstract

The invention provides a satellite program management system comprising an application memory configured to read, write and store an application program and a first backup application program; a bootmemory configured to be read-only and store a boot program and a second backup application program; and a controller used for controlling the second backup application program to repair the application program and / or the first backup application program, wherein the boot memory and the application memory are NOR FLASH. According to the present invention, the technical means such as backup, repair,loading control and dicing are further integrated, so that the reliability of application program storage and loading is greatly improved, and the workload of application program development is reduced.

Description

technical field [0001] The invention relates to the field of satellites, in particular to a satellite program management system and a satellite program management method. Background technique [0002] After the satellite computer is turned on, the bootloader (Boot Loader) runs automatically to complete the hardware initialization of the computer. The bootloader then loads the application on the storage into memory, after which the application is responsible for managing the computer and performing assigned tasks. The application program can be an application based on a general-purpose operating system or a dedicated software system. [0003] The satellite program management system is responsible for managing boot programs, applications and storage devices. Existing program management methods are divided into a backup method and a backup plus streamline method. [0004] 1. Backup method [0005] In backup mode, the bootloader is stored on the boot memory. Applications an...
