Development of high-speed attitude control system for the university satellite in measuring γ-ray polarization of transient sources

我们开发了一个工程系统的小型卫星TSUBMAME，4^<th>大学卫星的50公斤的质量，由东京工业开发。这一使命将是利用小卫星进行未来空间科学的重要开拓者。构建了硬X射线康普顿偏振仪、宽带脉冲监测仪以及基于控制动量陀螺的高速姿态控制系统的工程测试模块。我们表明，所有的系统工作得很好，以实现我们的科学目标，检测硬X射线/伽马射线偏振在各种瞬态源。

We developed an engineering system for a small satellite TSUBMAME, the 4^<th> university satellite of 50kg in mass, developed by the Tokyo Tech. The mission will be an important pathfinder for future space science using the small satellites. We constructed engineering test modules for the hard X-ray Compton polarimeter, wideband burst monitor as well as high-speed attitude control system based on the control momentum gyro. We showed that all the system works pretty well to achieve our science goals for detecting hard X-ray/gamma-ray polarization in various transient sources.
