摘　　要：利用卫星模拟遥测数据确定的卫星姿态是卫星发射中的重要参数。从几何姿态确定原理入手,研究如何利用遥测信息确定自旋卫星的姿态,列写了卫星周期、自旋角速度、两面角及太阳角的计算公式,分九种情况列写了卫星姿态的计算方法及公式,并对文中方法在海上测控任务中的应用情况进行了分析。It is very important to determine the attitude of satellite with analog telemetry data in the satellite launching project.Starting with the theory of satellite's geometry attitude determination,this paper studies how to determine the attitude of a self-spinning satellite by using its analog telemetry data and lists the calculating formulae of such parameters as satellite cycle,self-spinning angular velocity,dihedral and solar angle.The calculating methods and formulae of satellite's attitude in nine different cases are given respectively and applications of above methods in maritime tracking and controlling tasks are analyzed in detail.
