摘要
某遥感卫星,在发射入轨稳定运行期间,各项性能指标优于设计要求。由于陀螺停转导致卫星故障,主份贮箱燃料和蓄电池电源已耗尽,卫星处于自由旋转状态。通过实施一系列抢救控制方案,经过2个月左右的艰苦努力,将卫星恢复正常。抢救后的在轨测试表明,卫星各项性能指标与发生故障前相当。文章介绍了卫星抢救过程的控制技术及实施情况。
All the performances of a remote sensing satellite during operation are better than those required in design. Because of gyroscope＇s stopping work, the satellite gges in tumbling fault at high rate. By using a series of repair control schemes, after two months of endeavor, the satellite recovers. Through on-orbit testing, its performance is the same as before. In this paper the control technology and its implementation during repair are introduced in detail.
