摘　　要：针对气球吊篮对姿态控制的要求,本文给出以TMS320F28335为平台,开发设计出具有姿态数据采集、姿态数据处理、以及姿态实时监测功能的装置。姿态监测装置中用MEMS电子陀螺仪和地磁计获得姿态的采样数据,采样数据通过TMS320F28335解算为航偏角、俯仰、横滚三姿态数据,PC作为显示终端监控姿态实时变化,装置能够满足气球吊篮对姿态监控和测量的要求。In light of the Balloon-borne Gondola＇s requirements for attitude control, the paper takes the TMS320F28335 as the platform, designs and develops a device having the functions of attitude data acquisition, attitude data processing and real- time monitoring of attitude. In the attitude monitoring device, MEMS gyroscope and magnetometer are used to acquire the attitude sampling data, and the sampling data is decoded as three attitude data of drift angle, elevation and rolling via the TMS320F28335. PC is used as a display terminal of real-time changes of the terminal monitoring attitude, and the device can meet the Balloon-borne Gondola＇s requirements for attitude monitoring and measurement.
