Abstract This study presents a command-centric architecture (C2A), which is a satellite software architecture exhibiting a flexible reconfiguration capability. C2A was developed through the software development period of the Hodoyoshi satellites. C2A is a software architecture that describes all the actions of a spacecraft by commands to ensure that C2A can change the function of a spacecraft without rewriting the memory. By applying C2A to the software of PROCYON, the world's first 50 kg-class interplanetary spacecraft, it has become possible to reduce the development period and reuse some parts of the previous satellites' software. PROCYON's software was successfully reconfigured several times after its launch using the C2A characteristics. Because of this software architecture, it has become possible to develop reliable onboard software (OBS) for satellites in the short term.

以命令为中心的架构 (C2A)：具有灵活重新配置能力的卫星软件架构

摘要 本研究提出了一种以命令为中心的架构（C2A），这是一种具有灵活重构能力的卫星软件架构。C2A 是在 Hodoyoshi 卫星的软件开发期间开发的。C2A 是一种软件架构，通过命令来描述航天器的所有动作，以确保 C2A 可以在不重写内存的情况下改变航天器的功能。通过将 C2A 应用到世界上第一个 50 公斤级行星际飞船 PROCYON 的软件中，可以缩短开发周期并重复使用以前卫星软件的某些部分。PROCYON 的软件在使用 C2A 特性推出后多次成功重新配置。由于这种软件架构，
