We develop a small experimental platoform for space based on Space Wire standard. The main motivation of the development was to realize the easy-to-use or plug-and-play type environment for expriments in space. In order to develop spacecrafts in a short time without losing reliability, we stduy concepts based on network based architecture. Space Wire standard is adopted as the base of technology. We develop Space Cube 2, which is a generic multi-mission platform. It consists of three modules, the CPU, a Data Recorder and Power Supply modules. HR5000, which has been developed by JAXA, is the central processor chip of the system. The chip contains 64bit micro-controller based on MIPS 5kf architecture with maximum clock speed of 200MHz With integrated peripheral devices the chip enables high-speed communication and control. The first demonstration of Space Cube 2 in space has started from 2009 Feb. by using JAXA's technology demonstration satellite, SDS-1. In this mission, we use Space Cube 2 as a data acquisition computer for a user module that measure acceleration of free-falling test masses (SWIM experiment). Results of initial test phase shows that the system works well. The experiences gained from SWIM would play an important role for future experiments for gravitational wave measurements in space.

我们基于space Wire标准开发了一个小型的空间实验平台。开发的主要动机是实现易于使用或即插即用型的空间实验环境。为了在不损失可靠性的前提下在短时间内研制出航天器，我们研究了基于网络架构的概念。采用Space Wire标准作为技术基础。我们开发了Space Cube 2，这是一个通用的多任务平台。它由三个模块组成：CPU、Data Recorder和电源模块。该系统的中央处理器芯片是JAXA开发的HR5000。该芯片包含基于MIPS 5kf架构的64位微控制器，最高时钟速度为200MHz，集成外围器件，实现高速通信和控制。从2009年2月开始，利用JAXA的技术演示卫星SDS-1进行了“空间立方体2号”的首次太空演示。在本次任务中，我们使用Space Cube 2作为测量自由落体测试质量（SWIM实验）加速度的用户模块的数据采集计算机。初步测试结果表明，系统运行良好。从SWIM中获得的经验将对未来的空间引力波测量实验发挥重要作用。
