摘要/Abstract

摘要： 根据微型核定义开发了一套演示验证系统，它将星载计算机、姿态控制系统和通信子系统集成到一个被称为信息处理单元(IPU)的黑盒子中；IPU通过CAN总线连接微敏感器，包括星敏感器、太阳敏感器、磁强计、光纤陀螺以及GPS接收机。IPU尺寸为200 mm×28 mm×138 mm，净重为640 g，整个系统重量小于5.5 kg。利用作者开发的包括地面站系统和执行机构（反作用飞轮和磁力矩器）的航天器测试平台实现了微型核的自主姿态控制。

Abstract: Base on the description of general cell(GC), a demonstration system was developed with the volume of onboard electric system in 200 mm×28 mm×138 mm and dry mass 640 g. This demonstration system integrated onboard computer, attitude control system, and a communication subsystem in a black box called information processing unit(IPU). In the unit star sensor, sun sensor, magnetic meter, gyro and GPS receiver were connected by CAN bus and the whole system weighted less then 5.5 kg. In the same time the related spacecraft test bed includes ground station and actuators(reactive wheel and magnetictorque rod) and can realize autonomous attitude control.

Key words: spacecraft structure and design, general cell, microspacecraft, onboard computer
