我国在轨运行的卫星多次因红外地平仪受天体的干扰而出现姿态异常的情况.本文介绍了各种红外地平仪工作原理,分析了它们受干扰的原因,给出了精确预报的方法,并在此基础上提出了相应的抗干扰措施,有些已成功运用到在轨运行的卫星上. The satellites operating in orbit of our country appear many times because of infrared celestial bodies interfering with the celestial bodies, which lead to the abnormal attitude.In this paper, the working principles of various infrared geodesists are introduced, the reasons of their interference are analyzed, the methods of accurate forecasting are given, Based on this, the corresponding anti-jamming measures are put forward, some of which have been successfully applied to orbiting satellites.
