摘要
针对资源一号02B卫星运行中主份陀螺失效的问题,提出了通过在轨注入偏置动量控制程序到控制计算机(AOCC),将三轴零动量控制系统转为偏置动量控制加磁控的方案.给出了整星偏置动量控制器设计,通过在轨飞行数据分析了该方案的实施效果.该卫星转为无陀螺的偏置动量控制的成功经验,为三轴零动量卫星在关键部件(如陀螺、动量轮等)故障时实现高可靠运行提供了一种设计方案.
CBERS-2B satellite＇ s scheme was switched from zero-momentum control to biased-momentum control and magnetic control by uploading the control program to AOCC, when the main gyros were inva- lid. The implementation of biased-momentum control is described and the telemetry data analysis is sup- plied to evaluate the satellite＇ s flight. It was a successful experience for this kind of satellites to settle a stable flight with high reliability under the failure of crucial devices such as gyro, momentum wheel.
