摘　　要：实际应用中,由于遥测故障或脉冲重叠等多种原因,获取姿态脉冲信息时,可能缺少某些测量脉冲,为姿态确定的方法选择造成一定难度。针对海上测量弧段,某自旋卫星在红外地中脉冲丢失,仅有地出脉冲以及太1、太2脉冲时的几何定姿方法问题,通过对其原理、概念进行分析,制定自旋卫星红外地中脉冲丢失情况下定姿的方案与方法。该方法主要用于海上实时姿态监视,应急情况下也可以用于姿态的粗控。该研究为航天测量船应用测控软件的设计提供了良好基础。Because of the reasons such as telemetry failure and pulse overlapping,the acquirement of attitude pulse may lose some information,which causes difficulty for the selection of attitude determination method.Through the theoretical and concept analysis of the situation that there are only earth-out pulse,sun pulse 1 and sun pulse 2 but without the infrared central earth pulse of one spin satellite on the maritime telemetry arc segment,this paper proposes a method of attitude determination on the infrared central earth pulse absence for the spin stabilization satellite.The method is mainly applied to the real time attitude monitoring on the sea,and it can also be applied to the rough control of the attitude in the emergency situation.The research provides a favorable basis for the design of the spacecraft TT&C ship application tracking & control software.
