Abstract

The invention belongs to the field of aerospace and provides a micro satellite on-orbit reconstruction frame system and method. The system comprises an application layer, a system interface layer and a terminal drive system. The system interface layer comprises a core calling layer, a data exchange layer, a first interface form and a second interface form; the core calling layer calls and operates corresponded application layer modules of the application layer through the first interface form; the data exchange layer transmits external data input and output requires of the application layer to a corresponded terminal drive layer interface module through the second interface form. According to the embodiment, corresponded application layer module or interface drive layer module addresses can be called, modified or regulated through the first and second interface forms, on-orbit reconstruction software can be operated, the software adaptability is improved significantly, and the requirement change of the micro satellite research later period or on-orbit period can be met effectively.

Description

technical field [0001] The invention belongs to the aerospace field, and in particular relates to an on-orbit reconfiguration framework system and method for a tiny satellite. Background technique [0002] In the current micro-satellite research and development model, on-board software is developed in accordance with software engineering requirements, and together with the entire satellite, it is tested, launched, and in-orbit as a whole. Currently, satellite on-orbit mission updates are implemented through code annotations, and the main implementation methods include: [0003] 1. Note on the software code as a whole [0004] During the operation of the satellite in orbit, the ground will inject the modified and recompiled entire software code onto the satellite through the high-speed uplink channel, and jump the current software operation to the above-mentioned software operation through instructions, and the original software will be discarded. [0005] 2. Use the hook...
